The Airex Industries DCCH cartridge collector series distance themselves with the ability to filter highly contaminated air volumes while remaining extremely compact. The cartridges are combined with an efficient self-cleaning system of compressed air allowing the filtration of sub-micronics dust particles in a continuous operation and with a constant differential pressure loss. Our DCCH cartridge collector series includes sealed mechanisms and access doors for easy access and requires no tools to carry out the change of filter cartridges. |

The dust laden gases enter through the side intake of the cartridge collector hopper, under vacuum or pressure (except for bin vents, where the air comes in form the bottom). The gases are then filtered through the cartridges, and exit through the venturis, into the clean air plenum. The clean air can be exhausted outside or recirculated depending on application. |
The automatic cleaning system operates as follows : For each row of cartridges, there is a diaphragm valve, connected to an air tank. The diaphragm valve of the cartridge collector is opened in sequence by a solenoid valve and electronic control board. Short pulses of compressed air are injected through calibrated orifices in the blow tubes, into the venturis. The small primary flow of air through the venturis generates a much larger secondary flow of clean air from the plenum. The combined air flow creates a downward moving pressure wave, that breaks the accumulated dust cake on the cartridges. The electronic controller allows only one row of cartridges to be cleaned at any given moment thus ensuring the cartridge collector can operate continuously. |
