Used portable screw air compressor 500l for regenerated cotton yarn:

Combination valve patented technology
*Combined air valve is the special kind of high efficient energy-saving and long life new combination air valve.

*Structure by into trachea-shaped valve and exhaust valve combinations, the main features below :air through the intake manifold valve cavity, along the tangent of the valve flow, impact of approximate straight lines, air valves and flow resistance greatly reduces, so it could provide low noise, long service life.
*Because of the inlet valve inside the vertical spatial distribution, inlet of the valve flow area increased, the valve flow rate and lower drag coefficient, inspiratory volume increase volume efficiency, reduced energy consumption.
*Intake and exhaust valves is the reed valve and strip-type valves fixed unlimited free elastic beam opening and closing movements, without friction and clearance volume small so kotech combined air valve has excellent dynamic performance and reliability.

Especially suitable for: water and electricity, PET bottle blowing, leak detection, military and other fields

1. Valve materials are made of Sweden stainless steel band.
2.In order to ensure that air compressor highly reliable, using a redundant design principles, setting multiple protection measures: unloading, down drain, exhaust, ensure that the zero-pressure start.
3. Timed drain valve: Drainage and drainage at a time interval can be adjusted. Ensure that the captain of an air compressor runs continuously between regular drainage, effectively preventing water too much liquid strike accidents.
4. Low exhaust temperature(10.0Mpa exhaust pressure, exhaust air temperature ≤170 degrees, the temperature of exhaust air is above ambient temperature of 15-20 ℃ from after- cooler )
5. Fuel consumption per hour less than 0.143/kw.
6.High reliability and long maintenance period, very low fuel, low energy consumption and so on, greatly reducing the overall general operating costs.
