Chloroethylene Screw Air Compressor

Simple integral design, less motion parts required and easy maintenance are the key to the success for UNITED OSD Chloroethylene Screw Air Compressor. Its special designed structure makes sure no leaking, professional in chloroethylene gas delivery.
UNITED OSD screw air compressor incorporates mechanics, electronics, neonatology and cooling (including after-cooling) together. Special foundation is unnecessary when products are installed at user’s sites. It is easy to move and install. As a rotating machine, there is no air flow impulse. So the noise is low.
Discharge end of air-end adopted pairs of tapered roller bearing and it evenly support load, then extend the lifetime of air-end. Highest grade of SKF bearing in air-end has a design of coolant tank. It avoids the damage from dry friction at start. Air-end introduced three-course mechanical seal which has a design of shaft seal with return oil hole and could 100% prevent coolant oil leakage. Ratio 1 to 1 gear has no speed adding help to slower rotate speed of the air end.  This can reduce the damage of air-end and noise of unit. Moreover, extend the lifetime of the air end.
High quality of resilient shaft coupling will cut down vibrate, noise and minimize damage as well.
The air inlet filter is equipped with a high efficiency filter element; one that specifically made for mechanical industry use. Advance technology of nanometer coating is adopted; Its high quality assures the well being of all foundations and extends the lifetime of filter.
High efficiency air/oil separating system
The high efficiency air/oil separating system is made by a canister with specially designed internal structure, a focusing-type separating core and oil-return equipment together it ensures the compressed air only  2ppm at the outlet.
Level One by mechanical separator, approximately 99% of oil will be separated.
Level Two Filter consists of specially designed multi-layer fiberglass assures a higher quality compressed air.
Level Three The oil return system ensures the oil contained in compressed air is nearly inexistent.
Chloroethylene air end adopts special dry gas sealing, it is called the newest gas lubrication with no contact, double ends sealing. No leaking of medium and no input of air. Compared with normal sealing, it is more effective.
We order high quality motors from professional motor manufacturers. They all adopt SKF bearing, installed with eject/discharge oil fitting. Anti-explosive Grade: EXD ⅡBT4, IP 54. Insulation Grade: F under B level warming up.
