Variable Speed Screw Air Compressor
(VSD) — Chicago Pneumatic
CPVS | Vapi Gujarat
Chicago Pneumatic CPVS variable speed (VSD / VFD) screw air compressors vary motor speed to match your air demand in real time — cutting energy cost by up to 35% versus a fixed speed machine. Models CPVS 40 to CPVS 100 · 5 to 13 bar · FAD up to 508 cfm. Supplied, installed & serviced by RR Enterprise — authorised Chicago Pneumatic dealer for Vapi & South Gujarat.
Chicago Pneumatic Variable Speed (VSD) Screw Air Compressor
A variable speed screw air compressor — also called a VSD or VFD compressor — varies its motor speed to produce exactly the amount of compressed air your plant needs at any moment. Instead of running flat-out and dumping energy during low demand like a fixed speed machine, it ramps up and down to follow the load, cutting compressed-air energy cost by up to 35%. Since energy is roughly 70% of a compressor’s lifetime cost, that is where the real savings are.
Chicago Pneumatic’s CPVS range delivers this efficiency from 40 HP to 100 HP, at working pressures from 5 to 13 bar, with free air delivery up to 508 cfm. RR Enterprise supplies, installs and services the full CPVS line-up. If your air demand is steady instead of variable, compare the fixed speed range; for 100% clean air see oil-free compressors. Complete the system with air treatment and AIRnet piping.
Every CPVS unit holds system pressure within a tight band, soft-starts to avoid current peaks, and is rated to ISO 1217 Ed.4 2009. RR Enterprise will log your air demand to confirm the exact energy saving before you buy.

Should You Choose Variable Speed or Fixed Speed?
A variable speed compressor wins where air demand changes through the day or shift — it follows the load and saves energy. A fixed speed compressor has a lower purchase price and is the better value where demand is steady and continuous at near-full load.
| Factor | Variable Speed (CPVS) | Fixed Speed (CPM / CPI / CPC) |
|---|---|---|
| Best for | Fluctuating / variable demand | Steady, continuous demand |
| Energy cost | Up to 35% lower on variable loads | Efficient only near full load |
| Pressure | Constant, narrow band | Swings between load / unload |
| Starting | Soft start, no inrush | Direct-on-line current peak |
| Purchase cost | Higher (pays back via energy) | Lower |
Not sure which suits your plant? RR Enterprise will log your air demand and recommend the most economical answer — often a fixed speed base machine plus a CPVS trim unit gives the lowest total cost.
