Industrial Dust Collectors

	Air Pulse System The Airblast Air Pulse System comprises of cylindrical felted fabric filter elements with internal zinc coated wire support frames. Contaminated air is drawn through the filter elements, the contaminant is deposited on the outer surface of the filter elements. Efficiencies of up to 99.99% can be achieved. Cleaning of the filter elements is achieved by pulsing compressed air through jet tubes mounted on the clean side of the filter element. The jet tubes are mounted above zinc coated venturis which increase the air volume injected into the filter element. The momentary reversal of air flow caused by the ‘Air Pulse’ creates an expansion of the filter element sufficient to break and dislodge the matrix of contaminant which has developed on the outer surface of the filter element.
	Cartridges for Dust Collectors Airblast utilise a Viledon Cartridge for dust removal as they not only give you more performance but also they have been proved to last longer than other manufacturers. This combined with their compact construction and economy make them an obvious choice. As the manufacturer with the widest range of non woven technologies, Freudenberg produce top quality materials for maximised filtering performance. Viledon dust removal filters are designed to meet the requirements of specific applications from the development of custom-made media through to the finished product. The Twist & Fix filter cartridges are available in four nominal diameters, each in standard heights of 300, 600, 1000, 1200 and 1500 mm, with injection-molded flange made of glassfiber-reinforced polyamide, for installation from the clean-gas or the raw-gas side. Airblast in certain instances also incorporate he pa dust collectors in their systems. Construction details The filter medium is protected by a centering collar. Patented spacer ribs on both sides of the flange ensure correct mounting as well as optimum sealing against the system’s air entering compartment.
	Control system A compact electrical unit controls our low maintenance reverse jet systems. This continuously displays the pressure differential across the cartridge allowing the condition of the filter elements to be monitored without interrupting operations. The unit is programmed to clean the cartridges automatically once a predetermined pressure differential has been exceeded. This prolongs the life of the cartridges compared to those used in conventional systems because the cartridges are only pulse clean when the filters need cleaning. The benefits of our systems over that of conventional systems are that they rely on continuous feedback from a pressure gauge. Using a conventional pneumatically controlled fixed timer system not only increases compressed air requirements but also will have detrimental effects to the cartridges by exposing the filter element to the forceful pulses of air often unnecessarily (i.e. when the cartridges are clean). Our units can also be fitted with audio or visual alarm systems to warn the user if the unit is operating outside the machines design parameters.
	Shaker Filter The Airblast ‘E’ Series Filter Modules are based on a standard design which results in similar methods of operation. Giving maximum efficiency whilst at the same time keeping capital and maintenance costs to a minimum. The filter media is arranged in the form of a multi vee section with a common base. The filter media base frame is sealed and bolted to a false floor within the main cabinet. The basic specification will include cotton media. However, other alternatives can be supplied dependent upon the peculiarities of the dust being handled. The ‘E’ Series filter modules are manufactured from heavy gauge mild steel sheet. All joints are of a welded or bolted construction and are sealed prior to painting. All ‘E’ Series filter modules are paint finished utilising a base coat consisting of a hard, durable isomer coating which offers protection against chipping, salt, damp and rust. The top coat is an industrial quick drying enamel, semi-gloss, all weather finish. The standard 4 cu. ft. quick release bin is positioned towards the front face of the filter module for easy access. A single action locking mechanism and positive location ensure a good air seal.
	Portable Dust Extractors Based on our Air Pulse Cartridge Collector with adaptations to suit site conditions. This robust portable extractor is fitted with four collection bins adapted to be emptied whilst the collector is still in operation. The floor-mounted fan has a higher-pressure rating allowing it to over come resistance caused by flexible ducts commonly used on site applications. By utilising a silencer the unit gives powerful dust extraction on sites where noise brake out levels is tightly controlled.
	Bin Balance By equalising the pressure between the dirty side of the extractor and the collection bin we are able to drop a plastic bag into the bin. By sealing the bag with a tie-wrap prior to its disposal the operative is eliminated from exposure to dust that he would normally be exposed to if the bin was tipped directly into a skip.
	Small Portable Extractor Fans Very portable extractor fans 500 to 2500 cfm rating available 240 or 110 volt 0.5 to 1.5 HP. Vent tanks or other enclosed spaces with these handy mobile units using flexible hoses. Dust retaining socks supplied on request. We supply socks to fit your existing unit.
