As a basic appliance, RAK filtering unit has been developed for cleaning the air from welding fumes, arising at mobile or stationary workplaces. It is designed for intermittent (easy access) use at welding stations of not significant emission of welding dust.
The device is efficient in capturing both, the dry, as well as viscous dust, that arise during welding the oil-laden steel sheet and while using the anti-spattering liquids in large amounts. Each device features four-step filtration system: pre-filter, filtering pad, compact filter and carbon filter, absorbing the part of gaseous contamination. At the moment the filters reach the limit pollution degree, replace them for new – they cannot be submit to regeneration.
