Frequently asked questions
Is there an ATEX version?
Yes, ATEX-certified versions are available.
What protects the pump against cavitation?
The integrated cell ventilation. It considerably extends the service life of the pump.
How is the compressor driven?
Depending on the vehicle, via power take-off and cardan shaft, V-belt or hydraulic motor. We work out with you and the body builder which drive is right.
Who supplies, installs and maintains it?
We do. As CVS representative, we supply compressors and vacuum pumps, advise on installation in the vehicle and take care of maintenance and repairs.
