Description:The water protection is one of the key units to ensure the laser tube safely running. The water protection is also called the Water Cutting-Off Protector which consists of a sensing signal, spring and switch. When there is water passing, the switch valve receives water flow pressure and pushes the spring to touch the sensor, and the sensor transfers signal to the control system or the laser power source for which it indicates feasible to work. When there is no water passing, it will transfer the signal to laser power source or the control system, and then it stops normal work. Through water protection installation, it can avoid the laser tube explosion caused by users from failure in switching-on water pump or laser water chiller.


• The water cutting-off protection of laser tube is a simple structure with small size but stable performance and long life-span.

•  All the parts are designed smooth and the water passing the protection area won’t occur residue.

•  This product is made of plastic and produced with a special "secret" process for which it appears high hardness and strong(not fragile).
