Air FIltration

Quantification of Air quality (laser testing)
CFS can support all air filtration needs whether that be for Clean room air using HEPA filtration, or, whether it be for room ventilation or compressed air. A call to CFS could save your company money in all areas of filtration. One of the most important aspects of air filtration is knowing what is in your "air stream" before a filter and what is in it afterwords. Only by testing can real assurance be gained. If you live near a diesel rail station your air quality will be much different to that in the open country and we can test and advise what you have and may need. CFS has purchased the latest laser particle testing equipment available and can measure to 0.3 micron as designated for HEPA filtration. Again why leave anything to chance, most filtration companies offer no technical support capabilities or internal test, CFS takes filtration seriously and leaves nothing to chance. We can test filters at your site if required and provide an analysis of the air quality outside your premises or on the outlet of your HEPA or other filter.

Airgard Type VIII Carbon Filter
FEATURES �¡ High quality carbon �¡ Robust modular construction �¡ High carbon content �¡ Special sizes available on request �¡ Available with handles and seals �¡ Low pressure losses ACTIVATED CARBON UNITS (ACU) For a modular approach to fume removal the ACU is the ideal solution. The ACU unit is manufactured from a number of carbon biscuits held in a vee formation within a corrosion proof metal casing. The carbon biscuits inside the units are 25mm thick and are also sealed into the frames using polymer which eliminates the possibility of any air by-pass around the carbon. PRE-FILTRATION Carbon filters are designed to remove fumes and odours and are therefore not able to filter fine particles and dust. If left unprotected, the life of the carbon is severely reduced. To protect the filters use pleated and bag filters to the correct grade; this will depend on the environment. SIDE ACCESS HOUSINGS These are housings which encompass the Activated Carbon Unit along with the Pre-Filtration (such as Bag/Panel Filters). All housings have a side panel which is removable so that access can be gained easily to replace the filters. This type of housing is ideal for adding to existing installations such as catering extracts or industrial ventilation systems. Options are available depending on the application. APPLICATIONS Activated Carbon dates back many years. In the first World War gas masks were filled with activated carbon granules to remove chlorine gas. Today Longar produces a wide range of carbon filters to deal with many noxious fumes and gases, whilst maintaining high levels of strength and low pressure loss. Major uses of carbon are in areas where toxic or offensive odours need eliminating. For example sewage works, hospitals, slaughterhouses, restaurant kitchens, airports, toilets, wash rooms, laboratories, office blocks and many more.

Carbon Filterr Housings
These are Galvanised housings that encompass the Activated Carbon Filters along with Pre- Filtration. The Activated Carbon Filters serve the purpose of filtering smells from all kinds of applications from Commercial Kitchens to Gas Turbines etc, whilst the Pre-Filtration will filter the following: Filter Removal Mesh Grease Filter Grease (EU2 50-80% Efficiency) Glass Panel Filter Grease (EU3 80-90% Efficiency) Pleated Panel Filter Dust/Mist (EU4 90% Efficiency) Bag Filter Dust Mist (F5-F8 40-95% Efficiency) HEPA Filter Smoke Removal (H10 95-99.99% Efficiency) The above selections of filters are what can be used in conjunction with the Housing and in most circumstances Options All housings come with a minimum of 1 removable access door in order to remove and inspect the filters, however you can have additional door as required. External or internal flanges are available and must be specified upon ordering. We can also manufacture Carbon Filter Panels to fit the housing instead of Carbon Units where access and height maybe an issue. Sliding Panels or Housed Unit. 20mm Panels or 45mm Panels Custom Sizes are available on request. Filter Replacement This is very much dependant on the number of hours of usage/type of cooking/airflow etc. Please call for a more accurate replacement indication.

They have been specifically developed for the collection of low micron and sub-micron particles.For this reason they are used extensively in the following critical industries to contain contaminant and assist in creating aseptic conditions: • Nuclear Establishments • Hospitals • Electronics • Clean Rooms • Pharmaceutical Production • Injectable Production • Laboratories • Film Production Deep Pleat Hepa Filters CFS offer the complete range of deep-pleated HEPA Filters,in addition to recognised ‘standard’ sizes and standard materials available generally. Many critical clean air installations are in use today, requiring specialist help from our design department. Advantages • High Flow Rates - The ability to handle the large air volumes and high air velocities encountered in modern air handling systems. • Low pressure drop - By optimisation of the filter design, the lowest possible pressure drop at these high flow rates. • High Efficiency - Guarantee high efficiencies and maintain these values across a wide range of high flow rates by utilising a large filter media surface that will allow sufficiently low velocities in the media to be obtained. • Compact size - We can provide a range of unit sizes that will allow the treatment of these higher flow rates whilst industry standard sizes. *Service Life and pre-filters* The service life of the Airgard Type 17 depending on the air flow rate, final resistance and dust concentration in the air supply. Operating costs can be reduced through the use of effective pre-filtering. Using low grade pre-filtering will only marginally extend the life of the HEPA filters however, if finer pre-filters are used then it is possible to increase the service life considerably. It is not unusual to add several years to the service life through the use of an effective pre-filter. As a guide good pre-filter should have a minimum dust spot efficiency of 80-85%(F7) and preferably 93-97%(F8) in conformance with ASHRAE 52-76 (EN779). Construction Only the highest quality materials are used in the production of high efficiency air Filters. Deep pleated filters and mini pleats use the finest quality filter media available from the worlds major manufacturers. All medias are water repellent anfd treated with an anti~fungicide solution. Careful selection of the appropriate media for each filter type provides a product range to meet the most stringent application requirements.
