Every unit undergoes a comprehensive 33-point factory process inspection and 100% operational run-testing before shipping. Built with precision-matched rotors and fewer total mechanical components, this AC screw compressor drastically reduces operational failure rates and unplanned downtime in demanding commercial systems.

Featuring an internal discharge check valve, this high-performance AC screw compressor prevents reverse rotor rotation during system shutdown, protecting internal profile surfaces from abnormal friction. An integrated internal safety valve guards the unit against severe over-pressure spikes during transient operating conditions.

Designed with an accessible semi-hermetic body, this AC screw compressor allows field service technicians to easily inspect and maintain core internal assemblies. An external oil filter element and pre-configured oil management fittings ensure swift, routine maintenance without full system tear-downs.
