28 VPAK Extended Surface High Efficiency Mini-Pleat Filters Lightweight and easy to install Classification Ranges F6, F7, F8 & F9 Excellent performance in difficult operating conditions. Low Resistance at High Airflow Description: Vpak filters are lightweight compact filters designed for use in industrial and commercial HVAC installations. The rigid design and pleated media pack with thermoplastic separators, ensure they deliver the desired air quality when used in variable air volume systems where they are subjected to repeated fan shutdown, high relative humidity and intermittent exposure to water. Due to their high capacity, Vpak filters offer many cost saving benefits; In new installations fewer filters are needed to handle the same volume of air compared to filters of the same size with a lower capacity. Fewer filters mean less installation space for the filtration system. They can be utilised in existing systems to increase the air capacity or improve air quality. Vpak filters achieve a high filtration efficiency with a low media resistance and a high dust holding capacity thus long service life. Construction: The filters utilise multiple mini-pleat media packs assembled in a V-bank arrangement. The mini pleat packs are formed by the use of continuous beads of thermoplastic material that serve as separators to maintain uniform pleat spacing. The V-pack arrangement is also unusually strong allowing the filter to withstand very high pressure drop without pack failure. (Burst pressure is 2000 Pa). The header and panels are manufactured from plastic with support struts made of extruded aluminium. These components result in a corrosion resistant, lightweight filter. The mini-pleat media packs are bonded inside the cell sides forming a completely unitised rigid filter that does not crack and resists damage during shipping and handling. The rigid design makes them quick and easy to install. The micro glass paper media is formed with coarser fibres on the air entering side and finer fibres on the air leaving side. This allows particles to be collected throughout the full depth of the media providing superior dust holding capacity. The micro glass paper media is water repellent and can withstand intermittent exposure to water without affecting filter performance. Vpak are the ideal choice in humid areas or where moisture is often present. Efficiency The filters are available with either average efficiency of 65% or initial efficiency of 95% (better than some competitive products sold with an average efficiency of 90-95%). Dimensions Filters are available in standard sizes only (see chart).

Applications: The filters are used in applications to offer relief from unpleasant odours created by cigarette smoke, food preparation, industrial processes and a variety of other objectional sources. Filters are generally installed into slides in ducts, however to ensure effectiveness, the filter should be installed utilising Filter Tech Sales panel filter mounting frames, which incorporate sealing gasket and spring clips to ensure a positive seal is formed against the filter face. To achieve maximum effectiveness, filters should be selected at lower than normal velocities to allow as much contact time as possible between the contaminant and the carbon media. Dimensions: Filters are available in standard sizes with standard depths of 45mm and 90mm, but are regularly supplied in non standard sizes to suit application.

58 Model PDA4524 & PDA9024 Disposable Panel Filters Incorporating Activated Carbon Impregnated Media Maintenance: Filters are disposable and should not be washed or reused. When replacing filters it is recommended that the fan is switched off so as no dust, which may dislodge from the dirty filter, is drawn through the system. Care should be taken to ensure new replacement filters are of the same efficiency and performance of the existing original filter, as replacing with filters of lesser performance may be in breach of local building codes. The filter panel is readily removed from the filter holding frame or slide. When airflow is restricted due to build up of dust, remove the dirty filter and place immediately in a sealed bag to prevent any contaminate from spilling out. Install new filter ensuring it is correctly installed so that there is no air by pass.

59 FTAC Activated Carbon Modules Model FTAC Activated Carbon filters are used in conjunction with ventilation and air conditioning systems for the removal of undesirable gases and vapours (odours etc.) from the air stream by a process called adsorption. FTAC filters are manufactured using high activity carbons for use in general air treatment applications, including commercial kitchens and industrial installations. The activated carbon used in FTAC filters is manufactured from specific grades of coconut shell, which produces high quality carbon that can meet the demands of general air treatment. Compounds and odours which are adsorbed with standard carbon include; Acetic Acid, Adhesives, Animal Odours, Asphalt fumes, Antiseptics, Bathroom smells, Body odour, Cheese, Cigarette smoke odour, Diesel fumes, Detergents, Fish odours, Gasoline, Hospital odours, Kitchen odours, Methyl Ethylene Ketone, Ozone, Paint odours, Varnish fumes. (For a more complete list of compounds contact a FTS sales representative.) A range of impregnated carbons, designed for removal of specific fumes, is also available to suit application. FTAC carbon filters consist of an outer frame manufactured from galvanised steel into which are fitted up to 12 individual galvanised steel framed panels, installed in a V configuration. Each individual panel contains carbon granules between two pieces of perforated metal, incorporating fine aluminium mesh to prevent any carbon dust carry over. The carbon is packed into the individual panels using vibration, to ensure there is no settling of the carbon in transit which may cause air by pass. FTAC carbon filters are installed by permanently fixing the outer frame into the duct work ensuring that there is sufficient support for the filters weight (see specifications). By fixing frames together, any number of filters can be installed to make up a filter bank to handle the required air quantity, however supports will be required to support the weight of the carbon filters. As the inner cells can be removed from one side of the filter only, it is critical that access is available to that side for servicing. The activated carbon filters are not designed to remove particulate, conventional particulate and/or grease filters should be installed on the air on side of the carbon filters to prevent dust or grease form blinding the carbon filter which will severely effect it s performance. The activated carbon used in the FTAC carbon filters will adsorb large amounts of odours before it s efficiency to adsorb odours decreases. When efficiency of the carbon decreases, the carbon can be easily replaced by removing the individual panels from the filter and replacing the carbon with new activated carbon which has equal performance to the carbon initially supplied. The new carbon should be installed into the panels ensuring there is no possibility of the carbon settling and allowing air by pass. Complete replacement panels are also available which are sealed so that there is no risk of their performance deteriorating whilst they are in storage.
