【Main Use】: Pneumatic blow/gun suction is an environmentally friendly industrial waste cleaning product that can quickly and effectively suck/blow various wastes or dust. 【High-Quality Materials】: Vacuum gun guns are made of high-quality ABS plastic and aluminum alloy materials. They have high hardness, and corrosion resistance, are not loose or rust, are not easy to age, and have long service life. 【Working Principle】: The pneumatic vacuum machine kit uses as compressed air as the power source, working pressure: 90MPa, vacuum suction power: 10CFM; the powerful suction/blowing ability after pressurization can achieve the effect of clear ash. 【Good Performance】: Strong wind-sucking wind, low energy consumption. The slender nozzle design can spray fast shots and narrow streams into deep holes and slits that are difficult to reach the area. 【Professional Design】: The outlet is very concentrated, strong, and large. Small compressed air volume, low consumption, large flushing power, energy saving. It is designed for high-efficiency blowing, which is an ideal choice for cleaning parts and surfaces.
