Airblast Eurospray's Air Pulse cartridge filters comprise cylindrical felted fabric filter elements with internal zinc coated wire support frames. Contaminated air is drawn through the filter elements and the contaminant is deposited on the outer surface of the filter elements.
Airblast cartridge filters can help to achieve efficiencies of up to 99.99%. Cleaning of the cartridge 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 an Ultraweb Cartridge for dust removal as they not only give you improved performance but have also been proved to last longer than other materials. This, combined with their compact construction and economy, makes them an obvious choice.
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 main benefit of this system compared to conventional systems is that it relies 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.
If you are investing in dust extraction in order to protect your operator or yourself from the risks of dust, why do you then have to put up with the dust problems associated with emptying the bin into a skip? 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 not exposed to the dust that he would normally if the bin was tipped directly into a skip.
