The PGZ Inverting Filter-Press Washer is a vertical, sealed system designed for high solid-content slurry filtration, washing, and pressure drying. Its inverting vessel design enables complete cake discharge without manual assistance, ensuring faster cleaning and minimized downtime. With filter plates up to 3 meters in diameter and fully automated operation, PGZ is widely applied in activated carbon filtration, crystalline solutions, and ultrafine powders, where efficient washing, drying, and contamination-free discharge are critical.
Allows complete discharge and thorough cleaning, reducing manual intervention and ensuring no material residue.
Up to 3 m, providing high filtration capacity per batch.
Closed system prevents contamination, with automated pressure drying, cake discharge, and multi-unit synchronization.
Wetted parts available in plastic lining, stainless steel, or titanium for corrosion resistance.
Positive-pressure drying and washing cycles deliver high cake dryness and reduced downstream energy costs.
