Gantry Filter Press

Product Overview
After pressurization by the hydraulic system, the filter pump delivers contaminated coolant into the sewage tank for pressure boosting. The pressurized dirty liquid is forced to pass through filter cloth, solid impurities are intercepted by the filter cloth, and purified coolant flows out through pipelines after entering the clean liquid tank. When the pressure inside the sewage tank reaches the preset value, filtration stops. Residual liquid in the sewage tank is discharged by compressed air, and fully dried filter residues are discharged as the filter cloth rotates.
Key Features
- Main structure consists of frame, hydraulic system, sewage tank, clean liquid tank, filter cloth transmission unit, liquid storage tank, filter pump and liquid supply pump
- Exterior surface adopts brushed stainless steel, beautiful appearance and easy cleaning (excluding liquid storage tank)
- Adopts positive pressure filtration, featuring large filtration capacity and compact overall size
- Integrated design, only needs connection with liquid supply and return pipelines for on-site operation, quick installation
- Filtration accuracy can be adjusted by replacing filter cloth of different densities to meet diverse processing demands
- Fully automatic operation, no full-time operator required
- After air drying, filter residues contain extremely low moisture, greatly reducing waste disposal costs
