DURAFLOW LONG LIFE BAG FILTER
Application
Ideal for use in most applications and particularly where glass fibre media is not acceptable.Tests prove Duraflow filters can last more than twice as long as conventional bag filters.This is achieved through the development of a new fibre and manufacturing technology. The filter media used in Duraflow is 3-4 times thicker than that of conventional materials, its density gradually increases towards the downstream side giving the filter outstanding dust holding capacity, coupled with low air resistance, resulting in longer life and reduced plant room down time. Duraflow ensures a constant quality clean air supply whatever the need.
Construction
Duraflow self supporting pockets are manufactured from a patented filter media with a built in pre filter.The media is enhanced by the unique blending of two fibre types, that on contact create a long lasting and consistent electrostatic charge.This allows the clean filter to achieve its full efficiency performance from day one and throughout life expectancy, whereas the efficiency of a conventional bag filter is well below its average when clean. The pockets are retained in a rigid galvanised header frame ensuring maximum stability in all applications.

GREASE FILTER
Application
Designed for general-purpose kitchen extract use, the Standard Grease filter is suitable for removing airborne fats and grease from the atmosphere. Regular maintenance by degreasing the panel ensures optimum performance at all times.The Baffle grease filter reduces the fire hazard above the heat source through its unique design concept of interlocking baffles.
Construction
Standard – The cell is produced using the fully enclosed frame method of construction, with a galvanised crimped knitted mesh core and galvanised weld-mesh grilles and frame. A heavy duty version is also available.
Baffle – A series of vertical stainless steel or aluminium air baffles are housed in a heavy- duty frame of the same specification. Each of the baffles is strategically aligned to create a complex path for the air to pass through. As the grease laden air enters this path the deposition of the grease occurs and the grease is captured without the risk of re-entrainment. Due to the smooth nature of the baffles, the grease runs downwards, and out through drainage holes and in to collecting trays located in the casing.
Range
Stock sizes available along with custom sizes to order. Handles and drain holes also available.
Carbon filters for removal of odours and VOC’s
Application
Used for the removal of offensive odours in a wide variety of applications such as office blocks, hospitals, theatres, cinemas and airports. Carbon filters are also used for the removal of toxic contaminants in industrial or commercial applications. Some unwanted by-products include mercury vapour, sulphur dioxide and hydrogen sulphide and the odours that can be generated by sewage works, slaughter houses, restaurant kitchens, toilets, wash rooms, laboratories and other areas. Some of these applications require chemically impregnated activated carbon to enhance efficiency. Also widely used by museums and galleries to protect artefacts and paintings.
Construction
Carbon Panels – A patented bonding process is used to bond the carbon granules together into a biscuit, which incorporates a non-woven fabric on both faces. This process produces a homogeneous panel of consistent quality and dimensional stability thus producing an even resistance across the face. Panels can be supplied unframed or bonded into a galvanised, stainless steel or aluminium channel to give a robust construction. Where the carbon to be used is impregnated or needs to be in pellet form, we offer a loose fill panel.
Rigid / Standard Carbon Bag – Panels are also available in a rigid carbon bag, bonded in a ‘V’ formation and housed within a polypropylene frame, these are available in three sizes and come with a standard 25mm header.
