SP Series

The SP is designed to optimize size, efficiency, and operation. This industrial electric air compressor is offered in a range of 60-125 hp. This versatile product is also remarkably quiet, operating at 66-72 dBa, with the acoustical enclosure. The small footprint and versatility of this unit make it a useful product for both metal and plastic fabrication facilities, and the food and beverage industry.

Features & Benefits

  • Three phase open drip motor options include 200/208/230/460/575 volts
  • Full voltage magnetic starter with 115-volt control power
  • Equipped with an enhanced display Q1 microprocessor, the controller is capable of web access monitoring and sequencing up to 12 compressors
  • SP16-Series air end manufactured by Sullivan-Palatek
  • One-piece inlet/check valve housing designed for dependable performance
  • The compressor is flange mounted to motor C-face for positive alignment


Expertly engineered to save energy and cut consumption costs, the Variable Frequency Drive (VFD) Series compressors supply the exact amount of air each shift requires. No more, no less. The VFD’s are some of the many industrial electric compressed air solutions offered by Sullivan-Palatek.

Features & Benefits

  • Wide power range for 208V, 230V, 460V, and 575V
  • Pressure transducer motor speed control
  • Factory Settings:
    • Programmable digital outputs
    • Digital inputs
    • Programmable outputs: four relays, four transistors
    • Eight programmable parameter sets with S-curves, power off function, PID process controller, electronic motor protection, internal timer. Output frequencies up to 160 Hz with output voltage stabilization; switching frequencies up to 16kHz; output phase monitoring.
    • DC bus circuit connection, moto thermal sensor connection, hardware current line
  • The VFD helps reduce energy. Operating at 70% capacity, the VFD consumes 10% less power than a standard compressor operating with on-off control and 20% less than a compressor with modulating control.
  • The VFD has a soft start feature that maintains a low starting current. It reduces stress on the site power supply and also reduces motor wear.
  • The VFD system complies with the Electro-Magnetic Compatibility standard and is UL/CSA listed.
  • The VFD system is not limited to a fixed number of starts per hour.
