Panel Filters are designed as a pre filter in air conditioning and air intake applications.


The G4/EU4 Pleated Panel filter is often used as a pre-filter for our Bag Filter, and is suitable for use in HVAC for offices, retail, education, food and hospital applications.  Disposable and economical for higher volume systems.

The G3/EU3 Glass Panel filter has a high dust and paint holding capacity, suitable for general air conditioning use, such as carpenters workshops, automotive, metal working, & paint shops.

In the G4 Carbon Pleated Panel filter, the activated carbon agent is highly porous with a vast amount of surface area, and acts on a huge range of odour substances, from combustion exhaust to cooking odour and paint and refinishing odours.

Our C-Cell Panel filter is a high efficiency filter, available in M6, F7 and F8 grades, designed for use in HVAC installations where the highest degree of air cleanliness is required. The compact design, larger surface area and low initial resistance make it an ideal alternative to ordinary bag filters and panel filters of similar efficiencies.

The G4 Carbon Pleated Panel filter is made from a polyester filter media laminated to rust resistant steel stiffening expanded mesh, impregnated with activated carbon, and pleated to increase the surface area.

The C-Cell Panel filter is made up of water resistant micro-fine glass fibre filter media, closely pleated and separated by continuous thermo-plastic bead separators. This design accommodates a very large quantity of filter media which offers a longer service life and low pressure drop.
