The AIDA blower does not require a liquid cooling nor a lubrication system.
The AIDA is an “oil free” environmental friendly pump: no pollutants such as oil or resins are spread out in the air.
The vacuum capacity of the AIDA pump is reached by an accurate control of the clearances between the rotors and between each rotor and the blower housing. Since the tolerances are very tight it is an absolute requirement to prevent the intrusion of an external solid element into the pumping chamber. Therefore the AIDA blower inlet manifold is designed to host an integrated filter to stop solid elements to enter and damage the pump.
