The Heart of EMAX Rotary Screw:
The Airend is the most important part of your compressor, it is the heart of the machine that actually compresses the air. That is why here at, Emax Compressor we use only the best German and Finland name brand airends. Most airends are only good for up to 40,000 hours and then they need a complete overhaul, with our airends they are good for 70,000 running hours as long as the unit is maintenance routinely and the correct oil is used. EMAX Compressor Gives you a 10 year warranty on all their airends!
All Emax Air Rotary Screw air compressors are equipped with these state of the art screw airend compressors manufactured in Germany and Finland. These airends have precision-aligned back to back tapped roller bearings with close tolerances guarantee long life cycles and outstanding reliability. Each air end is tested to meet consistent high quality standards.
Premium Industrial Motors
We use only premium industrial name brand motors to run our compressors. Emax uses only low 1750 RPM motors. We have chosen motors that come with the best certificates and quality assurances so we know that you are getting the best as well! We use High Efficiency motors constructed with superior materials, higher service factors, longer bearing lives, lower waste- heat output and less vibration. We also pass the motor warranty on to you for a full 5 year on single phase and a full 10 year on 3 phase!
Programmable Logic Controller
These rotarys are controlled by a user friendly Logika PLC (Programmable Logic Controller). This controller makes this unit bullet proof. These controllers have may many features that are extremely user friendly and easy to use. Here are some of its key features.

  • Adjust Pressure – to what pressure range you need. This can be set by the customer, this unit has a shutdown in case the unit goes over pressure. the unit has a maximum pressure setting – the computer 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 control when the unit is wired up if it is running backwards, it will sense a reverse rotation fault and shut the unit down
  • High Voltage Fault – if the voltage is 15% over the power supply voltage rated on the Emax compressor data plate, the unit will shut down. Also if the voltage is 15% under it will shut is down as well.
  • Over AMP Shut down – if the motor is pulling to 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, information on why it shut down is stored
  • Maintenance Service – Keeps track of when to change the air filter, oil filter and the coalescing filter along with the unit needs greased. When they need changed the PLC will sound an alarm.After changing you simply reset that filter 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 adjust this range anywhere in between. You can also set the high end down to a lower pressure where ever the customer unit pressure is desired. The Emax 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 screw compressor, so keep the pressure as low as possible.
  • Built in Timer -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 so it will restart as air pressure goes down to the kick- in set point.
  • On- line 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 PLC’s carry a 5 year warranty
  • Daily / weekly Schedule – This unit can be programmed to start in the morning, can shuts its self at lunch if needed and can turn itself in the even as well, or when ever needed.
  • Self Start – if the power is lost this unit will automatically restart itself, this eliminates a maintenance crew to have to restart 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 adjust the pressure to be the lead or the lag unit.

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.
