AIR FILTRATION

Flogard System supply a extensive range of air filtration filters to meet your requirements. These include primary filters and HEPA filters, take a look  below to find the perfect filter. Do not hesitate to contact our experienced team with any questions.

Primary Filters and Pre Filter Panels

Primary filters usually have a pleated panel design. A wire mesh holds the pleated fibre media in place. The pleats allow these filters to catch more dust (down to 4 or 5 microns). Consequently, these filters have a longer lifespan. This design also helps prevent dust sticking to the cooling coil, fan and motor in the AHU and also to the inside of the ductwork. Dust build-up on these elements can present a fire hazard and can reduce energy efficiency. Having a good primary filter will help protect the other more expensive filters in your AHU, such as the secondary filters.


We offer a full range of such filters in various formats – standard size panels, non standard sizes and high volume panels. Frame materials include standard card, beverage board and metal.

Secondary Filters and Bag Filters

Secondary filters are typically bag filters made of synthetic material.  The bag extends backwards as it inflates, giving it a large surface area to catch pollen, bacteria and smaller particles of dust. Look for synthetic media in these bag filters rather than glass fibre media. Glass fibre media can shed from this type of filter and potentially get into food. Synthetic filter media, on the other hand, is shatter-proof, environmentally harmless and performs equally as well as glass fibre media.

Also we can offer the complete range of bag filters ranging in size pocket numbers and depth and header sizes.

HEPA Filters and Final Filters

HEPA filters at the final stage of filtration are for those applications that need a higher level of contamination control. They comprise a galvanized steel frame with side handles for ease of handling.

The media is water-repellent matted micro-fibre. The fibre media is capable of trapping very small particulate contaminants from an air stream.
