Small Noise Rotary Air Blower, air blower, HC-301S, for wastewater aeration
About HC
Originated in Japan (Tohin Shoji Co., Ltd., more than 10 million sets of HC blower have been used in the whole world. B-Tohin has been producing this blower since its establishment in 1994 by advanced technology and equipment from Japan. HC blowers are widely applied in new rural construction projects in China and used for motorway service station sewage treatment.

Applications
- Wastewater aeration
- Mixing and aerating of hospital and laboratory waste products
- Conveying papers in offset printing operations
- 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
- Civil sewage treatment plant
Features
- Compact, low noise and economical 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, litter energy consumption that can't be surpassed by other competitors.)
- Stable operation, convenient installation. (In the case of small types, the blower can be conveniently installed and mere vibration produced if placed correctly, not requiring any other vibration-proof 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.)
- Superior material, ingenious structure, remarkable
- performance (All parts of the blowers are made of fine 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.)
- Simple maintenance, rare malfunctions, long using life, low speed of blower ensures small abrasion and long life.
Working Principle
The blower is so designed and constructed that air is sucked, 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 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 heat and noise from generating. In the same time, circumfluence of air in cylinder will not occur.
Standard supply of scope
HC Rotary blower's structure is exquisite. It mainly consists of blower main body, motor, air filter, air chamber, public base (and oil tank), oil dropping nozzle (made in Japan), driving device and other connection parts.
