The Airblast Filter Modules are based on a standard design which results in similar standards of ventilation to our cartridge collection system, giving maximum efficiency whilst at the same time keeping capital and maintenance costs to a minimum.
The unit extracts airborne contaminants from the blast room, helps to improve air quality for the operator, product quality and productivity of the facility. Utilising these performance filters, which have a unique self-cleaning cycle to enhance operational life, contaminated air is drawn in through the inlet to the filter by the fan. Initially, some pre-separation takes place as heavier dust particles lose momentum and fall into the hopper. Finer dusts are carried up to the filter elements where they are retained on the outer surface of the filter fabric.
The cleaned air passes through the filter fabric into the fan chamber and is discharged. At the end of the process or at the end of a shift the fan is switched off and the filter fabric cleaning cycle commences. It is during this stage that dust is dislodged from the filter elements and falls into the collector. This cleaning cycle requires no compressed air, reducing not only the services required but also operating costs.
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 as he would be if the bin was tipped directly into a skip.
