Used for separating air and grain at vertical and horizontal pneumatic carriage between floors. It runs coupled with cyclone or with filter. The cast body and the rotor were processed sensitively and they were adopted to the part assembling point conditions. They were designed as they are going to protect the air leakage in minimum level. The air lock located under the cyclone prevents the air leakage into the plansifter and provides the prodcut completely discharging from the system.
