Applications

Agitation and aeration for plating tanks and waste water Air supplier for plastic welding and blowing For mist spray of burner and in glass industry and others Wastewater aeration Mixing and aerating of hospital and laboratory waste products Conveying papers in offset printing operations High-speed way underground water treatment

Features

Compact, energy consumption. (It adopts the principle of air compressed by revolving movement. Therefore, although compact, the rotary  blowers display their powerful discharged capacity, low noise, little energy consumption that can\'t be surpassed by other competitors.) Stable operation, simple installation. (In the case of small types, the blower can be conveniently installed and mere vibration produced if placed correctly, not requiring any other anti-vibration device.) Resisting load changes, securing fixed air flow rate (For instance, if a rotary blower is used for sanitary treatment in the aeration tank, almost no air flow rate is decreased even if load becomes large due to the change in the pressure inside tank.) Air chamber equipped for dispersing air smoothly. (All models are provided with an air chamber, resulting in being free from air pulsation and air dispersed smoothly. performance (All parts of the blowers are made of superior material and are fine designed and manufactured. It is durable in use and free of trouble and deterioration of performance after a long time use.) Noise is very low suitable for sewage treatment of residence residential area and public places.

Working Principle

The blower is so designed and constructed that air is intaken, compressed and discharged  repeatedly while vanes protruding from the grooves of rotor are coming in and out by revolution of a rotor (rotating body)   set eccentrically inside the cylinder diameter. A minimum required quantity of oil is dropped to an oil dropping nozzle, then dropped into the cylinder always while operating in order to make lubrication for the purpose of preventing overheat and loud noise.

Standard supply of scope

HC Rotary blower\'s structure is exquisite. It mainly includes air filter, electric motor, blower body, air chamber, pulley, belt, public base (and oil tank) and oil dropping nozzle.
