Air Lock basically works on the principle of locking of air.
It locks the air in between the inlet and the outlet port and thus removes the heavy material such as dust, husk, etc from the cyclone.
1 HP Geared motor is connected to rotate the paddle wheels at a specified speed and eventually the particles are evacuated from the bottom of the system without breaking the air seal.
Airlocks serve a number of purposes that include acting as a sealing device against loss of air while maintaining a flow of bulk materials between components in a pneumatic conveying system.
Apart from this, it is also used as a gravity discharger for cyclone dust collectors or filters.
The features that it offers are robust construction, compact design which leads to less space requirement and lower maintenance.
