Side Entry Airlocks
Side Entry Rotary Airlock is used in applications where product shearing is a concern. The valve name derives from the offset inlet and outlet Flanges, where the product enters the side of the rotor instead of the top. On a normal valve, shearing takes place as the rotor rotates into the housing. When these two straight edges meet on a typical drop thru rotary airlock, this provides a pinch area where the product can shear and/or jam. With the side entry rotary airlock, the product is caught on the upswing of the rotor blades so that the product is constantly falling away from the shear point. The rotor pockets also do not fill up as completely, additionally reducing the likelihood of shearing. Lastly, the throat has a V shape which helps push product out of the way.
