Because conventional piston type compressor contains much oil in condensate and has much foreign substances including rust, it's not easy to use auto drain valve for this type of air compressors.  Now, thanks to the special condensate discharging device, GAON Auto Drain Valve becomes an excellent discharging solutions even for condensate which has much oil or foreign substances.

Features
1. Condensate Discharging Structure
Generally in case of floating ball type drain valve, its nozzle opens as much as amount of condensate, it can be blocked regardless of the size of nozzle hole. However, the nozzle of GAON Auto Drain Valve is not opened as much as amount of condensate, but makes complete open temporarily at a certain point by gathering some amounts of condensate. Therefore, every foreign substance is rapidly discharged to complete opening nozzle space by pressure without blocking.

2. The Structure with Excellent Durability
Mostly, rubber O-ring or packing is used for the nozzle of drain valve. Condensate contains much foreign substances such as chips and oil, which stimulate O-ring or packing with high pressure, and therefore, the life of valve tend to be shorten because of abrasion and destruction.  But, the nozzle of GAON Auto Drain Valve is made up of only high strrong stainless and ceramic so it shows very excellent durability with little abrasion.

3. Self-Decompression Function
After condensate in tank is discharged, air pressure is filled into drain valve, and in this situation, newly generated condensate cannot flow into drain valve because of air pressure which is filled into drain valve.  In order to solve this problem, the pressures of valve and tank becomes equivalent by laying pipes from valve to tank. Then, because the pressures of drain valve and tank become equivalent and condensate in tank flows into drain valve only by gravity, it can be blocked easily even by small foreign substance. And drain valve should be located on the lower level than that of tank bottom floor, and therefore, condensate will be discharged.  However, GAON Auto Drain Valve decompresses by itself, because condensate which is generated in tank moves into drain valve by the difference of pressure, there is no blocking possibility and it can discharge condensate effectively though it is installed at any level

4. The Structure Overcoming Oil Barrier
Condensate contains some amount of oil, if this oil is collected inside drain valve, small floating ball cannot float in low specific gravity of oil, and therefore, there can be a possibility which nozzle will not be opened. GAON Auto Drain Valve uses large enough floating ball and acts enough strength to open and close nozzle, and therefore, there is no barrier because of oil.

5. Easy Installation and No Operation Power supply required
Float method doesn't need to supply operating power such as electricity separately and can be installed simply.  After installing one-touch way of nipple to drain ball valve which is attached to compressor tank or air tank, connecting it with this drain valve using hose and fixing it with discharging hose, and then installation is completed.

6. Heating for Antifreezing
Where it might need antifreezing according to the installing environment, you should make a heating for antifreezing. This heater operates only below 5°C, and therefore, it needs low electricity consumtion and is safe.
