The Schulz SRP 4015 Flex is a variable-speed (VSD) industrial rotary screw compressor delivering 13–51 CFM at 125 PSI from a 15 HP IP 55 motor controlled by an integrated frequency inverter. The Flex line modulates output to match real-time demand, eliminating the unloaded-run losses of fixed-speed machines and cutting energy consumption by up to 38%. Designed for 24/7 operation in ambients up to 113°F, fully enclosed and sound-attenuated.

Why Variable-Speed

  • Up to 38% energy savings — variable-speed drive eliminates load/unload cycling losses; output matches demand exactly.
  • Constant pipe pressure — VSD holds discharge pressure within ~1.5 PSI of setpoint vs. ~14 PSI swing on fixed-speed machines, reducing wasted air at the tool.
  • Soft-start — no inrush current, no large service-entrance penalty; gentler on motor and electrical infrastructure.
  • ControlNet microprocessor — built-in monitoring, scheduled-maintenance alerts, remote operation capable.
  • Two-stage intake filtration — improves downstream air quality and protects the airend.
