Condition: good (used), Year of construction: 2009, Dust extraction,filtration,welding fume extraction,self-cleaning cartridge filter,pneumatic,vacuum TEKA AIRTECH P24 The main Podpfol Dw U Dox Ahlspt areas of application for the systems are industrial plants/welding shops where it is where it is not possible to realize spot extraction point extraction or where point extraction is not sufficient to maintain clean air on the shop floor. Side-mounted ducts with point capture point sucks in contaminated air air and lead it to the filter section. Here, contaminants in the form of fine particles cover the surface of the filter patron filter. An administered pulse of compressed air cleans the cartridge filters, automatically at the required intervals. After the impact of the compressed air, the particles collected on the surface of the filters break off off and fall into the dust tank. The cleaned air is returned to the work room through individually adjusted long-range nozzles. At the same time ejection of the purified air directs the contaminated air of the hall towards the toward the extraction channels. Filter cleaned by microprocessor controller with compressed air pulses during operation, thus high efficiency of the device. Low demand for compressed air thanks to the system "Power-Spray" The AIRTECH unit series is certified by IFA in accordance with EN ISO 15012- 1 or DIN EN ISO 21904-1/-2 and approved for welding fume class W3 as a permanent local extraction device of welding fumes.
