The filter uses a pneumatic airbag to keep an upper and lower platten together with a liquid tight seal while solid bearing liquid is pumped through the filter media. Once the pressure inside the filter has reached 30-40 psi,pressurized air is fed into the upper platten, forcing the remaining liquid through the filter media leaving a dry cake.
