Our range of filter media is widely used in Laboratory and Process filtration applications. We are able to supply circles from 21mm diameter to large discs of 1000mm diameter. The technical capability of the various grades of paper caters for applications requiring a very fast (25 micron) filter to a slower, finer filter paper rated at 2 microns. The following abridged data will give a rough idea of the grades available:

For process filtration we are able to supply sheets for Plate & Frame Presses (Johnson-type) and large discs for Sparkler-type presses. Again, these are available as fast, coarse filters or for fine filtration.

Filter Pads are also available in a range of grades, from coarse (60 micron) to fine (12 micron) and sterile (under 5 micron). These are supplied as sheets 400mm x 400mm, 600mm x 600mm or larger. All sheets are asbestos free.
 

A range of filter media is available for the following applications:

• Heavy-Duty Air
• Automotive (Passenger vehicle) Air
• Heavy Duty Lube
• Automotive (Passenger vehicle) Lube
• Hydraulic Oil
• Fuel (Including Diesel)
• Water & Coolant 

Automotive papers contain resins that improve strength and provide resistance to moisture and temperature. The paper usually requires some form of curing process.

HRH grades are available in the following resin categories:

Standard-Cure: Phenolic or Water based resins. Curing is by oven (usually 10 minutes at 150ºC) and sometimes pre-heating.

Low-Energy: A development that reduces the amount of volatile emissions present in some standard cure processes. Process requires less energy, (usually 2 - 3 minutes at 130ºC) during the curing process. With escalating electricity charges the end user benefits from a cost saving. Some grades are water resistant, or even washable.

No-Cure: These resins (e.g. Polyvinyl acetate) are used in applications where temperature and moisture resistance are not critical factors, e.g. Automotive Air. No curing is required, and extra heating has no effect on strength. These grades can be warmed by infra-red lamps to enhance pleat sharpness. The advantages of no-cure paper include: Lower installation & production costs and less floorspace required as no oven is required.

Environmental advantages of Water-based resins: Less energy required for curing, less (or no) phenol emissions, reduced odours and an improved workplace.
 

Our product range includes many types of spun-bond and air-laid non-woven media. For pocket filters we are able to supply 40%, 60%, 80% and 90% media.

Various grades of spun-bond media is available for fast (100micron) and medium (50 micron) filter rolls for removing impurities from coolants in grinding machinery and lathes.
