When the vacuum receiver is empty, the discharge flapper valve closes and establishes electrical contact which, in turn, starts-up automatic filter cleaning and the vacuum motor
The vacuum in the receiver brings the discharge flapper valve back to a fully closed position and causes the suction of material into the receiver where it settles on the bottom
The exhaust air passes through the filter, which retains dust and fine particles, and proceeds towards the pump to be discharged into the environment
When the material reaches the volume-fill sensor, the system switches off the vacuum pump.
The weight of material in the receiver causes the discharge flapper valve to open and the material drops into the machine hopper.
If the receiver is not completely emptied, the material prevents the flapper valve from closing and the system goes into stand-by. A new cycle cannot be started-up until it is completely empty
Vacuum receiver installed directly onto the hopper to be fed
