General Features: The 3GVFD Series uses variable frequency drive technology to automatically adjust motor speed to match actual air demand, delivering energy savings of up to 50% on indirect and up to 70% on direct energy costs versus fixed-speed dryers. Available in 6 sizes from 750 to 3000 CFM at working pressures up to 16 bar, it holds a pressure dew point as low as +3degC with constant ISO 8573-1:2010 Class 4 purity. It runs on CFC-free R410a refrigerant with zero Ozone Depletion Potential, meeting F-Gas regulations, and is controlled via an advanced HMI touchscreen with alarm history and remote monitoring. The compact, all-in-one design needs only a single electrical connection for plug-and-play, quiet installation.

Our air demand varies through the day and we are paying for capacity we do not use -- is there an adaptive dryer?
Yes -- the VFD Compressor Series uses a variable frequency drive to modulate with demand, cutting energy use by up to roughly 50% indirect or 70% direct versus fixed-speed operation.
We need to phase out older refrigerants for compliance -- what does this use?
It runs on CFC-free R410a refrigerant with zero ODP and F-Gas compliance.
What is the largest capacity available in this series?
Six sizes are available, from 750 up to 3000 CFM.
