Hydraulic exhaust fan HF800

Instead of using a conventional motor to drive the exhaust, the hydraulic exhaust fan uses the pressure generated by the flow of the liquid instead of the power to achieve the effect of exhausting the air. The exhaust fan draws indoor air into the pipe, and the hot air of the smoke is easier to concentrate in the upper part of the room than the air.

A special spiral groove is engraved in the bearing, so that the lubricating oil is uniformly squeezed when the bearing rotates to form a buoyancy between the shaft and the sleeve to support the shaft center, thereby reducing friction and reducing noise and prolonging the life. This type of fan is generally very long.
