Spirofil supplies synthetic woven (filtration) belts, particularly for dewatering (belt presses) and various drying processes. In addition, the program includes a range of synthetic woven filter cloth suitable for chamber or plate filter presses. Spirofil has a 24-hour service facility available that can provide immediate assistance, supply and/or mounting of synthetic woven belts and synthetic filter cloth.
Spirofil supplies various types of synthetic / plastic woven belts.

– Our product range covers all sludge belt press liquid filtration applications, such as:
– Dewatering of inert sludge from quarries or mines
– Dewatering of biological or chemical sludge from municipality sewage plants
– Pressing of grapes, fruit and others
In addition, woven belts have for many drying and transportation applications.
Synthetic woven belts are made with special first quality yarns in 100% polyester. Every woven belt is heat-set, granting a high degree of stability and long running life.
Spirofil is able to deliver the appropriate woven belt belt for each situation. Most applications can be supplied with the standard program. Below you can some examples. Please contact us for a personal advice in your trasnportation / filtration issue.

A special type of woven wire mesh belts is the so called double weave woven wire belt. This belt consist of two layers: a flat top layer and a support layer. Double weave woven wire belts are mainly used for solid/liquid filtration applications in for example (petro)chemical industries and water treatment, as a belt, drum or disc filter.
Advantages of a double weave wove wire belt are: good mechanical properties & long lif span, high flow rate, good cake release & cleanability, stable property against heat and thermal shrinking. Spirofil is able to advise the correct woven mesh belt for every suitable application. Please contact us for a personal advice in your transportation / filtration issue.
Our woven belt can also be equipped with guiding strips or gear drives. Below are some examples.

Synthetic woven filter cloth
Spirofil delivers a range of synthetic woven fabrics for filter cloths in order to supply as per the requirements of most plate filter presses.
Some examples are: traditional filter cloth, cloth for membrane plates, cloth with sealed edges and/or reinforcements, under cloth for drainage etc. Applications can be found in for example wastewater treatment and the food industry. The woven cloth is based on mono filament and/or multi filament yarn. A mono filament wire has a smooth surface. It allows an excellent cake release and a low retention capacity of particles.

A multi filament wire has a good retention capacity and an reasonable cake release. The combination of more small (twisted) wires together result in a high tensile strength. Combinations of wires are mono-mono filament, mono-multi filament and multi-multi filament. Available weavings are plain weave, twill weave and the so called satin weave.
The combination mono-multi filament in a smooth satin weaving is common applied because of the combination high strength, excellent cake release and easy cleaning.
Main applied materials are polypropylene, polyester and polyamide. A thermofixation treatment of the woven cloth give a high dimensional stability of the fabric. Finally, CAD/CAM and laser cutting equipment result in a high product standard.
