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.

Condition: excellent (used), filter area: 50 m², suction capacity: 650 m³/h, negative pressure: 38,000 Pa, High-pressure fume extractor, dust extractor, TEKA self-cleaning filter. Filter for plasma, laser. Due to its design, the system is particularly recommended for processing greasy, sticky fumes and dust. The device is equipped with an automatic system for impregnating cartridge filters and an activated carbon filter for neutralizing odors generated during processing. Ledpforhidmjx Afwsrr The filter is cleaned pneumatically with impulses of compressed air during operation, which results in high efficiency of the device. The extraction is designed for special applications where the filtered fumes and dusts may be soggy and sticky. By feeding the impregnant, moisture is captured from the smoke, which helps protect the filters from sticking. In this case, the life of the patron filters is extended. After the cleaning process, the control gives a pulse to the magnetic valve, located on the top cover of the powder-filled barrel. The applied magnetic pulse swirls the impregnant, which enters the suction pipeline. The powder covers the working surface and provides a protective coating for the filters.
