Advantages of OGFD Air Screw Compressor:
Features a pre-filter and uses a pleated filter, offering low pressure drop, durability, and removing 99.99% of airborne contaminants

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.

The plates are made of special 304L stainless steel, offering corrosion resistance and high heat transfer efficiency. This design minimizes pressure drop and temperature difference, ensuring the system operates under near-isothermal compression. The system features a compact design, requires less cooling water, reduces pressure loss, enhances durability, and is easy to clean and maintain.

AIRERA 11kW Screw Air Compressor: Frequently Asked Questions (FAQ)
Why is choosing an oil-free compressor for the 15HP (11kW) range a future trend?
As global industrial requirements for environmental protection and low-carbon operation increase, oil-free technology has become standard for precision electronics, and labs. Since 15HP is the "golden power range" for small-to-medium production lines, opting for an oil-free model helps meet environmental audits and eliminates fire and safety hazards caused by oil leaks.
What is the practical significance of "low vibration" in a direct-driven oil-free compressor?
The 1:1 direct-drive structure reduces unbalanced forces caused by belt tension, ensuring smoother operation. Low vibration translates to less mechanical wear, significantly extending bearing life and allowing the unit to be installed directly on the workshop floor without a reinforced foundation.
How does AIRERA control the discharge temperature of the compressed air?
We utilize integrated "After-cooler" technology. The hot compressed air passes through high-efficiency cooling fins for secondary cooling, maintaining the discharge dew point and temperature within an ideal range, which also reduces the workload on downstream dryers.
