The BEST Warranty In the Industry
Polar Air, by Eaton Compressor, backs all our rotary screw air compressors with the best warranty in the industry. With our extended warranty, we don’t ask you to buy a service plan, we just ask that you purchase and use our oil and filters. This ensures the correct oil and filters are being used, to keep your rotary screw air compressor running for years to come. We have 3 different extended warranty options to choose from so you can pick what best suits your company’s needs. Make sure to research and ask questions, when comparing warranty information. Be certain, when you buy, that you are getting a full warranty. Our trained service and support team is ready to assist you, if you ever need them and we carry a full line of air compressor replacement parts.Rotary Screw VSD/VFD Advantage Option over a Rotary Vane Compressor
A rotary screw air compressor is the most efficient in variable speed applications. Rotary screw units do not depend on centrifugal force to operate the compressor, like a vane type compressor. A vane-type compressor depends on the high RPM to slide the cylinder vanes to create compression. When pump speeds are reduced, a sliding vane pump loses RPM and its centrifugal force to operate, yielding more leak paths and lower performance, at lower pump speeds. Vane-style compressors also lose efficiency in higher PSI ranges. A rotary screw pump has a fixed rotor and yields more CFM efficiency, at higher pressure ranges, up to 218 PSI, if needed.
Our Programmable Logic Controller Puts You In Control
This 7.5 HP Rotary Screw Air Compressor is controlled by a user-friendly Logika PLC (Programmable Logic Controller). These PLCs have many features that are extremely user-friendly and intuitive. Here are some of its key features:
- Adjust Pressure to the range you need. In addition, this unit has an automatic shutdown, in the event it goes over pressure. Because the unit has a maximum pressure setting, the PLC will sense that it is going over pressure and will shut down.
- Low Oil Shutdown – if the controller senses that the unit is going into high temperature, it will shut it down. It will also shut down if the compressor runs low on oil.
- Reverse Fault – the controller will determine, when the unit is wired up, if it is in reverse rotation fault and shut the unit down.
- High Voltage Fault – if the voltage is 15% over the power supply voltage, rated on the Polar compressor data plate, the unit will shut down. As well, if the voltage is 15% under what it should be, the unit will shut down.
- Over AMP Shut down – if the motor is pulling too many amps, it will shut down. You can check the amp draw of the electric motor, as it is running, and also on the exhaust fan motor
- Clock and Date – built in Clock and Date to help keep track of preventative maintenance services.
- Light – has a built in light for dark locations.
- Parameters – has a maintenance parameter system to create and maintain the parameter and control information.
- Hour Meter – built in hour meter to keep track of the running hour on the machine.
- Fault History – the PLC stores history, if the unit shuts down, and can provide information on why the unit shut down.
- Maintenance Service – keeps track of when to change the air filter, oil filter and the coalescing filter, along with a schedule of when the unit needs greased. When any of these issues need addressed, the PLC will sound an alarm. After addressing the maintenance issue, you simply reset that element back to zero and start the maintenance tracker again.
- Air Differential Control – with differential control, you have a wide range of pressure settings. You can take the kick-in pressure all the way down to 100 PSI and all the way up to 145 PSI. You can also adjust this range anywhere in between. The Polar Compressor is factory-set at 120 kick in and 145 kick out. The lower the pressure, the higher CFM and the more hours you will get on your rotary screw air compressor, so keep the pressure as low as possible.
- Built in Timer – this component will sense when the unit is not being used for a period of 20 minutes, under no load. This will shut down the machine, automatically, and it will restart, as air pressure goes down, to the kick-in set point.
- Online Demand – this setting is made for high volume and will bypass the automatic kick-off mode. It allows the unit to keep running on continuous run mode for high air demand.
- Warranty – these PLCs carry a 5 year warranty.
- Daily / Weekly Schedule – this unit can be programmed to start in the morning, can shuts itself off at lunch, if needed, and can turn itself on based upon a pre-programmed schedule.
- Self Start – if power is lost, this unit will automatically restart itself, this eliminates a maintenance crew to have to restart it, after the shut down.
- Master Slave – this controller can switch from one unit to the other and maintain the same use of hours. It can also adjust the pressure to be the lead or the lag unit.
The Heart of your Rotary Screw – Energy Facts About Rotary Screw Pumps
We utilize Rotorcomp EVO2 Air Ends. Their oil-injected screw air ends are the heart of our air compressor system. Utilizing best-in-class components, we’ve built the perfect air compressor system with ultimate efficiency, low noise, engineered to provide years of reliable service. These pumps offer:
- Ultimate efficiency with reduced noise
- Long life cycle due to increased bearing dimensions
- Quality assurance test on every compressor before leaving our factory
Our rotary screw air compressors offer 100% duty cycle which means that you can operate your compressor 24×7 without the need to shut it down to avoid overheating.
These high-efficiency pumps are more expensive to utilize in our manufacturing process but the years of dependable service they provide is worth the additional investment. We have thousands of satisfied customers across the country who agree.
100,000 Hour Bearing Performance
Most rotary screw air compressors, on the market, are only good for 20,000 to 40,000-hour pump bearing life spans. Rotorcomp pumps are good for up to 100,000 hours on the pump bearing life.
Premium Industrial Motors
We use US Motors brand electric motors that meet or exceed National Electrical Manufacturers Association (NEMA®). This helps save money, due to increased energy efficiency over other air compressors on the market.
- Motor is not only built with a larger conduit box for easier connection, it has superior sealing for better environmental protection.
- Full cast iron construction is more robust than the standard rolled steel, ensuring reliability in extreme duty applications.
- With longer fins for better cooling, the motor runs at a lower temperature, increasing the life of the winding insulation. A cooler running motor delivers higher efficiency.
All of our motors are low RPM 1,750, not 3,450 RPM, unlike other lesser quality air compressors on the market. Our energy-efficient motor increases starting torque by 2X. Low RPM also minimizes harmonic distortion for a quieter, more reliable compressor.
Switch Gear & Variable Speed Drives by Schneider Electric
Manufactured by Schneider Electric, our switchgear and variable speed drives are UL/CSA compliant. Schneider contactors are used for Y/Delta soft start, saving our customers up to 33% in energy costs during startup. Schneider variable speed drive option gives our customers up to 7X starting amp savings and up to 40% savings while the unit is in operation.
With a global presence in over 100 countries, Schneider Electric is an industry leader in Power Management – Medium Voltage, Low Voltage and Secure Power and in Automation Systems, providing integrated e efficiency solutions, that combine energy, automation and software to deliver comprehensive energy-saving solutions.
VMC Inlet Valve
The Air-end is an integral part of a rotary screw air compressor, but is does not work alone. The outside air is brought in and filtered, before it hits the inlet valve, to ensure it is receiving clean air. The inlet valve regulates the amount of air that is drawn in by the rotary screw. When the valve is in a loaded state, it is compressing air and pumping it into the air-end. When it is in an unloaded state, it shuts off the air supply, so the motor and screw are turning, but not taking in air, and not pumping any air to the system.
Our VMC inlet valves have a counter-weight, which ensures a fast, tight close, when the air flow is reversed. This load and unload system means greater energy savings as well. When running the compressor in the unloaded state, it allows the compressor to store more air than is being use (a storage tank must be used in this case). The larger the storage tank, the longer the no-load cycle time, which increases savings.
This unit will save you a significant amount of money on your electric bill because, under start up, the modulator valve is completely closed. This closes the air off to the screw intake, making low load under start up. After the unit gets started, it has a 12-secound time delay. This allows the unit to begin running for 12 seconds, before it starts pumping air. This no-load startup will extend the life of the magnetic starter contractor and motor, because of low amp draw.
Premium Mann Filters
Filters help protect the compressor from wear and damage. It is the most inexpensive way to prevent potentially costly repairs. It is vital that these filters are replaced and inspected on a routine basis, as it reduces the chances of component and air-end contamination. Not changing the filters, on a regular basis, decrease the energy efficiency of the compressor. We use only genuine Mann Filters. These Filters are not exclusive to us, therefore, after your warranty is up, you will still be able to find these parts. Mann Filters are made with exceptional quality and provide optimum protection against harmful elements. Our rotary screw air compressors also have Pre-Filtration, on the outside of the cabinets. Although this is an upgraded feature, it is one that is well worth the cost to extend the life of your compressor. Even in environments that are not particularly dirty, the build up, over time, can be damaging to the system and negatively impact the performance of the compressor. Ask about adding a Pre-filter Kit to your system, to save even more money.

5 reviews for 7.5 HP Rotary Screw Air Compressor with Dryer Package, Single Phase, Dual Volt, Fixed Speed – PRS007P120V
Add a review
I purchased a compressor from Eaton almost a year ago, upon receiving the equipment; I was impressed with the quality and on how it was crated to be shipped so not to be damaged in transit. About after eight months I had a small problem, Thought o-boy, here I go, warranty, yea right!
I have never been one for purchasing because of the so called warranty- Matt made a believer out of me! Never have I been treated so well and dealt with such pleasant, honest, knowledgeable and faithful to their word people, as the people at Eaton Compressor.
Now with how they took care of my problem with the unit, just put my faith back into believing in people.
Not only will I recommend Eaton equipment but I think even more important, Matt Cain has proved he stands for honesty and integrity, and there is not more a person can ask for.
Matt, and to all at Eaton Compressors, hats off to all of you-
YOU MAKE “AMERICAN MADE” LOOK GREAT!!

We bought one compressor from you back in July. We have not had any issues with it, its running 24hrs a day here and all seven days/week. I didn’t know a lot about compressors when I started the search for one. I got a lot of quotes on a 30HP Rotary Screw from all the local dealers, was shocked at the prices. It was nice to find you on EBay and get a reasonable quote that we could afford. Thanks for the help.

I love my compressor and look forward to receiving my new dryer from Eaton. Your service and products are outstanding. Thank you for being a company and a people of integrity. I pray the Lord bless you all.
The outstanding and quality products from Eaton Compressor can only be surpassed by the quality and integrity of those whom own and operate Eaton Compressor.
My story is long, so I will highlight my experience as briefly as I can. I researched compressors and dryers for 2 months. I finally bought a 10 horse Polar Air Rotary Screw Compressor from Eaton Compressor. All American made and a great warranty at what I believe is a very good price!
I got my compressor in, it looked as though it had a rough trip from the delivery company. It did. It had been dropped!
I called Eaton and was put in touch with one of their lead techs Bert. He was ready to assist me on finding out if we could fix what was damaged during transit. I could not talk with Bert until after 6pm at night, this gentleman gave me his cell phone number to call him when I could. I called him and it was clear that he was at a game for one of his kids, yet he still took my call! In short, I needed another compressor. The next day on their day off Matt and Tina, the owners called me to let me know a new compressor was on it way. Wow! The next day I ordered my dryer!
I have been in the Auto-body trade for 35 years and of that been a licensed and ordained minister for 22 years. In my years I have never met a company full of more integrity and honesty in my life! From Megan on online sales to Susan in the office from Bert in the trouble shooting field to Matt and Tina the owners, all full of integrity and honesty! Eaton Compressor is the very example of American Exceptionalism. I am in California between San Francisco and Sacramento in the valley. I welcome anyone that would like to check out the exceptional products that Eaton Compressor sells to come by my shop! Email me at timlandis1963@yahoo.com. You will not be disappointed!

Megan kept me informed of the shipping date after the order and shipped the compressor on a Thursday, we received it Friday, the next day! Great service!
We got it installed the next morning and it greatly exceeds our expectations. Quiet, pumps a LOT of air, and I’m super glad we went with the variable speed motor. It seems very efficient and slows the whole unit down when there isn’t as much demand for air in the plant. As for performance, it filled our 120 gallon tank up in 1 minute and 5 seconds.
If you’re thinking about purchasing this compressor, just do it. It will exceed your highest expectations.

This machine is such a beast! After shopping various brands, numerous factors lead me to 20 HP Variable Speed Rotary Screw 120 Gal with Cooler and Dryer Polar Air by Eaton. This compressor has become the back bone to my custom cabinet shop that contains a paint booth, numerous air driven pocket screw machines, air driven hinge machine, air over edge band machine, air over wide belt sander, air over CNC and upwards to 5 DA sanders operating at a time. I was literally melting pistons in pairs of 5 HP 80 Gal stand up piston driven IR compressors. I needed more air to grow my business. Polar Air Customer service was 2nd to none, I was able to speak directly to a very knowledgeable sales woman, and then directly to Mr. Cain who answered all of my questions and outfitted me with the proper machine for my needs. After shopping various brands which require “Factory Certified” start up and maintenance, Polar Air’s maintenance/warranty schedule was a no brainier for me. They are so confident in their product, you buy a service kit from them once a year, your 10 year warranty is honored…too easy. I just completed my 600 hour break in service and it was so straight forward and easy. QUIET!!! Goodness this unit is so quiet for what it does. I would say it was no louder than a household blender. The control panel on this unit tracks all of your use and maintenance schedules. Since we are in a dusty cabinet shop, we added the prefilters to the compressor cabinet with excellent results. The cooler and dryer unit is a must in the humid South East and that has also improved my overall finished product, and is pushing much higher quality air into my expensive machines. I cannot say enough good things about not only the quality of this machine, but the quality of the air it produces. The company was an absolute pleasure to deal with and I would gladly recommend this product to any one that needs 80+ CFM of cool dry air to make a living with.
