Advantages of OGFD Air Screw Compressor:
- Air Filter
- Patented High-Efficiency Compressor Block
The compressor block is constructed from 304L stainless steel,featuring a world-class sealing system that integrates mechanical seals,an air curtain chamber, labyrinth seals, and a bypass channel into a single unit.
- Unloading Valve
The independently designed unloading valve (Patent No.: ZL200520058468.2) is specifically engineered for vortex characteristics, enabling the screw compressor to achieve a fully sealed operation with 0–100% capacity, ensuring stepless air delivery.
