Variable Speed (VSD) Rotary Screw Air Compressors, 10-75 HP

What a variable speed (VSD) rotary screw compressor is A variable speed drive (VSD) rotary screw air compressor changes its motor speed to match the air your shop is drawing at that moment, instead of running flat out and cycling on and off. Every compressor here is a PM VSD screw compressor: a permanent-magnet motor on the same shaft as the airend, run by an inverter, rated for 100% duty cycle at up to 145 PSI. The saving comes from the hours your shop uses less than full air. AERO rates these units at up to 35% lower energy use than fixed speed, depending on your demand profile, running hours and energy prices. A shop at full load all shift gains less. Standalone compressor or All-in-One package? A standalone unit is the compressor only: airend, motor, inverter, controller and enclosure, with a G3/4" to G2" outlet. You add the receiver, dryer and filters. Buy standalone when you already own a tank and dryer, want a larger tank or a remote dryer, are piping a central system, or need 40 to 75 HP. Buy an All-in-One package for the compressor, refrigerated dryer and ASME tank on one frame, 10 to 30 HP. No 3-phase service? See the 5.5 and 7.5 HP single-phase models. The seven models, 10 to 75 HP CFM is at 100 PSI; every model reaches 145 PSI and needs 3-phase power.

Read how to size an air compressor or ask for a sizing quote. What every unit includes Direct-drive rotary screw airend and oil-cooled permanent-magnet motor on one shaft: no belts, no couplings, no gears INOVANCE inverter, the variable speed drive, standard on every unit MAM6080 touchscreen controller with WiFi and real-time monitoring IP54 enclosure; every panel lifts off on quarter-turn latches SKF bearings, Saint-Gobain oil seals, Schneider Electric contactors The PM motor is about 10% more efficient than an asynchronous motor. CTA multi-stage filtration is an option on each model. What you add An ASME air receiver, 80 to 260 gallons, stores air for peak draws. A refrigerated air dryer, sized by compressor horsepower from 42 to 370 CFM, takes the water out before it reaches your tools or paint. Line filters after the dryer catch oil and particles. Ask us to match all three. Lead time, freight and financing In-stock machines ship in 2 business days; each product page shows current stock. The VSD75 is quoted per shop.
