Sullivan-Palatek VFD
Rotary screw compressors
Expertly engineered to save energy and cut consumption costs, the Variable Frequency Drive (VFD) Series compressors supply the exact amount of air each shift requires. No more, no less. The VFD’s are some of the many industrial electric compressed air solutions offered by Sullivan-Palatek. The VFD helps reduce energy. Operating at 70% capacity, the VFD consumes 10% less power than a standard compressor operating with on-off control and 20% less than a compressor with modulating control. The VFD has a soft start feature that maintains a low starting current. It reduces stress on the site power supply and also reduces motor wear. The VFD system is not limited to a fixed number of starts per hour.
