Drag move energy-arm welding fume dust purification device movable mechanical filter, is designed to accommodate a variety of welding places and conditions. Filtration system has a robust metal construction of the housing and coated with anti-corrosive paint, designed for everyday use type. Can load four rubber wheels can move freely to ensure the workplace, three meters long suction arm can rotate 360 ??degrees. This can easily be extended to where it is needed the arm. Filtration and purification systems are ideal means to solve your problem of dust absorption. The dirty air pipe to collect absorbed by pre-filters to distinguish between coarse particles. So, after crude filtered air through the filter effect in 99.5% of the primary filter, clean air side is connected to the grid via two machine aspirated back workshop. A control lamp can show whether the filter needs to be replaced inside the filter layer, the cover can be easily opened to replace the filter layer. The durability of the filter layer is a filter purifier features. Welding fume purification equipment advantages 1, the electronic control over current overload protection device, the structure is simple, safe, easy to operate; 2, advanced fan design, air volume, low noise, low power consumption; 3, polytetrafluoroethylene cartridge (filter effects> 99.9%), long life, can absorb dust particles 0.3μm to capture the effect is obvious, to eliminate the fine dust particles damage to workers; 4, the use of 360-degree activities, universal suction arm, can sucked from the flue gas at the flue gas occurs, greatly improving the collection rate of soot; 5, dust inside against fire hazards and large particles of slag with a three protective measures, so that dust longer life, more secure : 6, suction hose using a real temperature, wear-resistant composite materials, cracking due to Mars will not burn, the longer life; 7, with a dedicated band brake casters, convenient, casual mobile devices and positioning.
