Removal of condensate from compressed air system is a critical maintenance requirement. Failure to carry out regular draining results in serious disruption to production schedules, deterioration in product quality, and damage to sensitive pneumatic equipment. Eliminates the risk of human error and possible costly aftermath by providing regular system drainage.
A drain valve is simply a device that allows excess moisture to be drained from the compressed air system. It is used at low points in the system where water collects. The valve mechanism can be opened to allow water to drain out via gravity and closed to prevent air from escaping once the water has drained. Drain valves may be found on compressors, air dryers, air receiver tanks, inline filters, and at low points in the compressed air piping. They should be used anywhere moisture may collect in the compressed air system. Sunwin’s most popular drains includes float drains, electronic drains and zero air loss drains.
Zero Air Loss Drainer
Removal of condensate from compressed air system is a critical maintenance requirement. Failure to carry out regular draining results in serious disruption to production schedules, deterioration in product quality, and damage to sensitive pneumatic equipment. Eliminates the risk of human error and possible costly aftermath by providing regular system drainage. Compared with traditional drains, zero air loss drains save compressed air energy and is a more cost-effective choice for you, Sunwin’s most popular zero air loss drains is WK-58, which is float type ball zero air loss drain, no electricity required, usually installed under the air tank with large capacity of 680L/H.
◆ Automatic cleaning function.
◆ Remove condensate without wasting compressed air.
◆ Large-diameter valve nozzle, easy to discharge oil, rust and pipe scale.
◆ Long-life all-stainless steel valve nozzle design, pressure-resistant design.
◆ Large-volume: double-layer strainer.

Float Type Ball Drainer
It is often used to automatically remove accumulated water at the bottom of pipelines, refrigerated air dryers, oil-water separators, air storage tanks and the bottom of various air filters. It can be installed in places where it is inconvenient to discharge sewage manually, such as high places, low places, and narrow places; especially in places with large gas consumption and frequent water discharge, it can prevent the compressed air from being forgotten due to artificial drainage. Water is re-polluted.

◆Die Casting Aluminum Shell, Powder Coated
◆Stainless Steel Float Ball & Hardware
◆1/2″ NPT Female Inlet and Outlet Connection
◆Equipped With “Anti Air Lock” Vent Tube Discharges Condensate “Not Air”
Condensate from the filter will flow beside the vent tube and accumulate in the drain reservoir. As the condensate accumulates the liquid will cause the float to rise and force air out through the tube and discharge valve expelling the liquid. After the liquid is expelled the float will return to the low position and the discharge valve will closes until the cycle is repeated. Each float type ball drainer is equipped with an “Anti Air Lock” vent tube which prevents loss of compressed air.

Electronic Drainer
The SUNWIN electronic auto drainer controlled condensate drainer combines an adjustable electronic timer controlled drain, a ball valve and a mesh strainer into one compact easy to install package. Suitable for any flow range and pressure up to 16bar (230 PSI), the drainer is perfect for virtually any compressed air application, especially those with solid particulate contaminants.
◆Available in High Pressure (up to 40Bar)
◆Easily adjustable electronic timer
◆Direct acting solenoid valve
◆Large discharge orifice
◆Cost effective
◆Test switch, LED on/off indication
◆ON Time: 0.5 – 10 Seconds
◆OFF Time: 0.5 – 45 Minutes
◆Brass body with stainless steel internals
With a test button, LED on/off indication and a full serviceable direct acting valve, the drainer offers affordable, reliable condensate management without the need to install additional valves and strainers. Use it on any compressor, receiver, filter or refrigerated dryer. The saves installation time and protects against large particles found in condensate, thanks to the integrated ball valve and strainer. The unit can be shut off from the compressed air system, enabling easy and safe work to be carried out.
