Description
STS 40 High Pressure Piston Booster – Reliable Pressure Boosting up to 580 PSI
The STS 40 series by South-Tek Systems is designed for applications where standard compressed air must be elevated to significantly higher pressure levels, reaching 580 PSI with stable and continuous performance.
Its fixed-speed piston design ensures mechanical robustness and resistance during prolonged operation. The IE3 motor optimizes energy consumption, while low-speed operation reduces internal wear, extending system service life.
Available in either cabinet-mounted or open-frame configuration, the equipment offers installation flexibility according to space availability and environmental noise requirements. The microprocessor-based control panel allows monitoring of key system parameters to ensure reliable performance in critical applications.
Applications
PET blow molding systems.
Hydrostatic and pressure testing.
Automotive industry.
Industrial processes requiring ≥580 PSI.
High-pressure instrumentation applications.
Specialized manufacturing plants.
Continuous industrial operations.
The STS 40 High Pressure Piston Booster is ideal for any application requiring reliable pressure above standard compressor output.
Advantages

Mechanical Engineering for Extreme High Pressure
The STS 40 series by South-Tek Systems incorporates robustly manufactured compressor blocks with concentric suction and discharge valves designed to maximize volumetric efficiency and extend service life under high-pressure conditions.
The motors supplied by WEG S.A. are non-proprietary, facilitating maintenance and spare parts availability. The equipment features Class F insulation for thermal protection during prolonged operation.
The microprocessor-based control system includes:
- Optional touchscreen display
- Integrated phase protection
- Current protection for main motor and fan motor
- ABS enclosure with IP65 protection rating
