Applications
For oil-free compression of gases and vapors in combination with a backing pump Short cycle
Pumping processes also in the presence of large quantities of gas and vapor
Advantages to the User
Two air-cooled series, each with four models.
Reliable and trouble-free
Sealing rings with their housing can be readily replaced.
Shaft seals and elastomer seals made of FPM/Viton.
Standard motors in accordance with IEC dimensions
Be easy to exchange with custom motors.
Integrated pressure equalization line for protection against overloading at high pressures on WAU models
Pumping direction may be changed as required Ex T3 and T4 motor possible
