High-Pressure P400HPR Compressor


With the P400HPR compressor, users can achieve pressures of up to 250 psig with 3 compression stages, all within the P400 power range. Its aero design ensures peak performance and delivers substantial energy savings compared to conventional dry screw or oil-injected screw compressors. 


With its high discharge temperature capabilities, the P400HPR is an ideal fit for Heat of Compression (HOC) drying applications, further enhancing energy savings within your compressed air system. Meeting ISO 8573-1, the 100% oil-free compressed air guarantees no oil transfer in the air stream. 


The P400HPR can be optimized with the R1000 Control System or the PLC-based R2000 Control System featuring either a Siemens or Allen Bradley platform. Equipped with advanced features like a user-friendly interface, real-time data visualization, Energy Advisor, FS-Connect remote monitoring, and seamless integration with existing systems, the Regulus Control System empowers operators to optimize compressor performance, reduce energy consumption, and ensure reliable operation.
