Pan Filter Covers
Sefar pan filter covers for rotary and tilting pan filters deliver high filtration efficiency, reduced soda content, and long lifetime for alumina hydrate and phosphoric acid production.
Increase Yield with Consistently Clear Filtrate
Clear Filtrate
Minimize soda and suspended solids with covers designed for high filtration clarity and throughput.
Longer Uptime
Fast, trouble-free installation and extended service life reduce your operating costs and filter downtime.
The Right Solution for Your Filtration Challenge
Our pan filter covers are precision-engineered for rotary and tilting pan filters in demanding chemical applications. They deliver excellent filtration rates, easy installation, and long service life, maximizing output while reducing downtime.
Rotary Pan Filter Cover
Custom-fit covers ensure continuous operation, high flow rates, and minimal solids in clarified acid while boosting yield and reducing maintenance needs.
Filter Media Technology
Sefar provides a dedicated selection of filter media tailored to the specific demands of each filter type. Our broad fabric portfolio ensures the optimal match for filtration performance, chemical resistance, and mechanical stability, while our fully integrated value chain makes dedicated scale-retardant filter media available.
SEFAR TETEX® MONO
SEFAR TETEX® MONO is a robust monofilament fabric ideal for pan filter covers. It offers excellent particle retention, fast drainage, and low filtrate turbidity, helping reduce soda content, improve clarity, and extend filter service life.
Made to Fit.
Exact Fit for Every Filter Type
Each cloth is cut to exact dimensions for the filter type. This ensures an exact fit, prevents leakage, and supports consistent filtration results with minimal installation effort.
- Chemical & Thermal Resistance
Withstands high temperatures of up to 100°C and harsh chemicals from pH1 to pH13, ideal for both hemihydrate and dihydrate processes as well as soda content reduction in alumina hydrate. - Filter Capacity
Optimized fabric liquid permeability and drainage behavior enable efficient cake dewatering, supporting faster cycle times. - Filter Efficiency
A broad selection of dedicated weaving designs, offering optimized pore size distribution ideally matched to the process particle size requirements.
Sefar pan filter covers are compatible with equipment from leading manufacturers, including:
Andritz, Bokela, FLS, Hongda, Prayon, RPA/Hasler, UCEGO, and Westech.
