Atlas Copco DZS 300P Dry Claw Pressure Vacuum Pump Oil Free Industrial Compressor

Atlas Copco genuine DZS 300P dry claw pumps deliver certified oil-free vacuum and low-pressure air for demanding industrial manufacturing processes. Engineered with dry claw technology, this unit operates completely without lubricating oil inside the pumping chamber, eliminating process contamination risks in electronics fabrication, plastics extrusion degassing, and automated CNC vacuum hold-down.

In standard industrial configurations, the 300-class claw platform delivers a nominal pumping capacity of approximately 300 m³/h, achieving continuous deep vacuum levels down to 140 mbar(a) while maintaining high volumetric efficiency.

The compression mechanism utilizes two precision-synchronized claw-shaped rotors rotating in opposite directions within a dry stator housing. Because the non-contact claws never touch each other or the internal casing walls, friction wear is eliminated and internal friction-induced power loss is significantly reduced compared to traditional oil-sealed rotary vane pumps.

The pumping chamber remains completely dry and isolated from the gearbox by pressurized atmospheric air purge barriers and durable shaft seals, ensuring that no oil vapor backstreams into process lines. Precision internal clearances maintain high continuous pumping speed across a wide operating pressure profile, preventing the sudden capacity drop typical of worn mechanical vanes.

To withstand harsh industrial vapors and humid process gases, the claw rotors are protected by proprietary corrosion-resistant and anti-stick coatings that prevent surface particulate adhesion. The DZS design features a modular dry pumping chamber that allows fast access for routine cleaning and particulate removal without disassembling the drive gearbox or disturbing timing gear synchronization.

Operating capacity and ultimate vacuum levels depend on motor frequency (50 Hz or 60 Hz) and positive-pressure versus vacuum piping configurations. Please provide your electrical voltage and process pressure specifications from the machine nameplate to verify exact technical curves.
