RF-PLF Series — Pressure Leaf Filter Fabrics
Custom-fabricated filter cloths and leaf bags for vertical and horizontal pressure leaf filters. Precision retention for edible oil dewaxing, chemical clarification, and catalyst recovery.
Series Overview
Pressure leaf filters use stacked filter elements (“leaves”) immersed in a pressure vessel. The filter cloth or bag covers each leaf, capturing solids as liquid passes through under pressure. This design is widely used for polishing, clarification, and pre-coat filtration where clear filtrate and consistent retention are essential.
The RF-PLF Series provides precision-tailored cloths and bags that fit your specific leaf dimensions, OEM model, and application requirements. We match material, weave, and retention rating to your process chemistry and target particle size.
Precision Retention
1–120 µm range
Chemical Resistant
Full pH range
Custom Tailored
Leaf-specific fit
Clear Filtrate
Polishing-grade
Key Features
Defined Pore Size
Controlled weave structures deliver consistent particle retention from leaf to leaf and batch to batch. No bypass, no turbidity spikes.
Exact Leaf Fit
Every bag or cloth is cut and sewn to your specific leaf dimensions and frame type. Tight fit eliminates wrinkles and bypass channels.
Pre-Coat Compatible
Smooth fabric surfaces support pre-coat (DE, perlite, cellulose) build-up for polishing filtration. Uniform cake formation across the leaf.
Clean Discharge
Easy-release surfaces and monofilament constructions ensure spent pre-coat or cake releases cleanly during blow-down or vibration.
Reinforced Edges
High-stress areas around the manifold connection and leaf frame are reinforced to prevent premature failure and extend cloth life.
OEM Compatibility
We supply leaf bags and cloths for all major PLF manufacturers including Filtration Group, Sparkler, Eaton, and others.
