Six new filtering units were installed in the mechanical repair shop of the branch "Production of non-ferrous metal alloys" JSC "Uralelectromed" (an enterprise of the metallurgical complex of UMMC). This equipment is used for air purification during welding, cleaning, grinding and other works with metal. They are especially important in welding, during which welding aerosols containing toxic substances are emitted. - The new installations, in contrast to the existing stationary ones, are more compact, lightweight and easily moveable to any equipment in the shop, - said Vitaly Kungurov, head of the RMC branch. compact frame with a rotary-exhaust device. They are equipped with a coarse metal filter, which simultaneously acts as a spark arrestor, and a fine filter with replaceable cartridges, which retains welding aerosols. A centrifugal fan is located in the casing of the unit. It creates the necessary vacuum. The fan is equipped with an original aluminum impeller. This design, as well as the use of aluminum instead of steel, improves noise performance. As a result, the noise level during the operation of the unit is reduced to 50 dB - the volume of calm speech. The units also provide a self-cleaning function in the form of shaking up the accumulated dust. After shaking, the worker sweeps away the fallen dust and disposes of it, and the installation remains clean and ready for further work.
