Brand: SEWO? Westlake Product Features: · sanders and dust integration groupings, reasonable structure, small footprint · Unique design element, increasing the filtration area, free removal type · Automatic mechanical vibration mode cleaning, no air and cleaning fan · Compact Vacuum shields, improve cleaning efficiency and operational safety devices ? Dual wheel symmetric configuration, conducive to grinding machine running smoothly, improve equipment utilization · Built-in pre-dedusting (spark deposition device) and overload protection, eliminate fire hazards · equipped damping device, keep the device low-noise operation works: When the device is activated, sanders and dust while booting, the workpiece grinding dust particles generated by the fan suction under negative pressure into the settling chamber , large particles, heavy dust particles falling directly on the fouling drawer, fine dust into the air filter chamber, when the dust through the bag when the bag attached to the surface of purified gas flows through the fan clean room, the silencer into the atmosphere. In order to maintain the original machine cleaning effect, please clean up the dust in the work after the end of the right side of the red rocking vibration gray ball, the timely processing of the dust bag, regular maintenance can help long-term durability.
