The Schulz SRP 4020E Dynamic packages a 20 HP industrial rotary screw airend (74 CFM @ 125 PSI) inside a fully-enclosed, sound-attenuated cabinet engineered for 24/7 continuous duty in ambient temperatures up to 113°F. The Dynamic line is the workhorse of the Schulz fixed-speed lineup — IP 55 totally enclosed three-phase motor, integrated 24V control panel with service disconnect, and a high-efficiency air/oil separator that delivers oil carry-over below 3 ppm.
