Industrial filtration

High performance textiles for all types of liquid filtration

For the filtration of your coarse and fine particles, Subrenat designs efficient, high-flow filtration media that can be adapted to your machines.

Our non-woven filter fabrics are made from materials carefully selected for their specific properties:

Viscose: a natural fiber with excellent absorption capacity, ideal for filtering frying liquids in the food industry.

Polypropylene (PP): a lightweight material that is resistant to chemicals and temperature, perfect for industrial liquid filtration in the mechanical and automotive sectors.

Polyester (PET): high mechanical and thermal resistance, excellent for industrial water filtration and fluid cooling.

We demand the best for your filter media

Coarse filtration

Coarse filtration is designed to retain coarse and thick particles.

Our PP and polyester filter media are designed to withstand heavy loads and maintain a constant flow rate. Viscose, which is highly absorbent, is ideal for filtering frying liquids.

These filter cloths are compatible with gravity belt filters, a continuous industrial liquid filtration system in which the filter media moves under the effect of gravity to trap particles in a collection tray. A simple, economical and robust solution.

Direct filtration

Direct filtration, or cake filtration, forms a deposit of particles (the ‘cake’) on the filter media, which then acts as a co-filter.

Subrenat offers two-dimensional filter media in medium to high grammages, suitable for all types of filter:

Gravity filters: passive filtration by the weight of the liquid,

Pressure filters: filtration accelerated by external pressure,

Vacuum filters: filtration by suction of the fluid.

Depth filtration

Depth filtration retains fine particles throughout the thickness of the fabric.

Our needle-punched polyester felts offer a 3D effect that combines surface and internal filtration. They promote the rapid formation of a filter cake, reduce clogging and extend the life of the filter media.

This technology is ideal for industrial liquid filtration in machining, cutting fluids and high-precision environments.

Industrial filtration for the automotive and mechanical industries

For the mechanical, metallurgical or manufacturing industries, especially those using robotic machining, our textiles provide filtration solutions for machine maintenance and production efficiency:

High-strength PP: effective filtration of cutting oil, even at high temperatures, for complete cooling and longer machine life.
Process water filters: reuse industrial liquids by removing particles and impurities.
Plate filters: modular systems for constant flow and easy maintenance.

Industrial liquid filtration for the food industry

For the food industry, our filters are particularly suitable for filtering and cooling cooking oils (chips, crisps, etc.).

Viscose: perfect for filtering frying liquids (chips, crisps) thanks to its high absorption capacity.
High-strength PP: allows the oil to cool completely, even under intensive conditions.
High-strength PET: stable at high temperatures, suitable for all types of food cooling.

Industrial water filtration and fluid treatment

For water treatment plants and systems, we offer chemically compatible filters designed for optimal flow and filtration efficiency of your process water.

High-strength PET: durable, stable and high-performance for industrial water cooling.
Viscose: effectively absorbs used cooling liquids.
Hydrophilic PP (PP HY): specially developed to optimise cooling in water-based processes.
