Profile: Polex Environmental Engineering Pty. Ltd. is a specialist designer and manufacturer of industrial air filtration equipment. Our product line includes dust collectors, spray booths, scrubbers, cyclones, fans, vehicle exhaust extraction systems, fume arms, rotary valves and ducting. Coupled with the supply of equipment, we offer full system design and turn-key installations. We also provide workable solutions to existing plants by way of extensions, improvements, and on-going service. The Polex reverse-pulse modular bag filter dust collector series is of a robust and efficient range of dust collectors. These units are ideally suited for continuous operation, since the filters are continuously cleaned while in operation. Polluted air enters through the side panels (beneath the filters) or the hopper, and is directed upwards through the array of cylindrical bag filters. The larger dust particles drop out into the hopper, while the lighter and finer particles continue into the array of filters. The cleaned air then enters the clean-air chamber where an array of blow-tubes are positioned. The tubes blast compressed air into the filters to help release the dust. The cleaned air is then discharged into the atmosphere, or through discharge ductwork. Our dust collectors are designed with common components in mind. The interchangeability of components for different sized dust collectors minimizes stock levels required, and allows for fast delivery of assembled dust collectors. Components are stocked for all models and assembled to order. Each Polex dust collector module is 1090 mm deep x 1090 mm wide. Our dust collectors are modular, and can therefore be easily extended as the airflow requirements through the system increase, without having to replace the entire dust collector.
