AIRTECH Central suction and filter unit is used in industrial plants / welding shops where it is difficult to exhaust the polluted air from a production hall. It is a good tool to prevent air pollution. The polluted air enters the systems via the lateral suction ducts with intake points located at 4 m height and is guided into the filter section. The polluted particles then deposit on the surface of the filter cartridges. Compressed air automatically dedusts, at required intervals in the filter cartridges. The next step involves release of particles that have stuck to the cartridges by compressed air blast and are collected in the dust container. The cleaned air returns to the working space through a long range ejector nozzle that is adjustable. The polluted air is thrown out.
