KDOF Series

Two-stage oil free dry screw air compressors are impressive not only because of their meticulous design, but also these innovative details based on the product quality of Kotech group.

ISO 8753 Class 0 certificated:

100% Oil-free dry screw compressor produces no pollution, ensuring the purity of compressed air and safeguard your product.

Long-term high efficiency:

Kotech two-stage oil free dry screw air compressor is durable and ensures a long-term and stable compressed air production because of its optimized two stage compression design.

The Kotech two stage rotary screw air compressor have maximum efficiency and performance that can be driven up to 500kw. So it can even meet the volatile compressed air demand requirements.

Chromium Steel Rotors:

The rotors of the two-stage compression are made from stainless steel, which eliminates the risk of rotor seizing or jamming caused by corrosion.

Durable Coating:

The blasted rotors are treated using the special “Ultra-Coat” process to produce an innovative and durable coating which is resistant to temperatures of up to 300°C, because this cost-reducing coating is highly abrasion-resistant, its sealing and protection performance remains consistent even after years of operation.

High efficient air end cooling:

In areas that require cooling, the coolant directly passes through the inter layer of the air-end’s casing, taking away high temperature heat to ensure good heat dissipation and maintain good compression efficiency.

Complete unit:

Oil-free dry rotary screw compressor with two-stage compression; condensate separator, condensate drain and fibre-free pulse dampers for both compression stages; oil tank ventilation with micro-filter, ready for operation, fully automatic and silenced.

Friendly Service:

The oil-free air compressor is designed with a wide maintenance door and a swing-out cooler, which make maintenance so easy.

Siemens control system:

Full-text display, 30 languages available;soft touch icon keys; “traffic light” style, LED to indicate operating status; fully automatic monitoring and control.

Ventilation system:

Powerful ventilation and cold box design gives it excellent heat dissipation effect, ensures the low temperature inside the compressor unit.

The main advantages of 100% Oil Free Dry Screw Air Compressor are:

1. Adopt oil free GHH air end made in Germany.
2. It offers efficient compression with low operational noise, long service life and no air pollution since there is no oil involved.
3. Low maintenance costs, as minimal care and maintenance is needed, resulting in lower running costs.
4. Oil free screw compressor has various applications in industrial purposes, such as food and beverage, medical, electronics and many more.
5. It is compact in design and can fit into any tight spaces.
6. It provides a clean and dry compressed air, ideal for sensitive and critical applications.
