The Evolution no-smoke self-supporting suction arm represents the best technical solution for the suction of welding smoke, gas, vapours, aerosol, oil fumes, dusts, etc..
Operating Principle
The polluted air is sucked in through the jointed hood and passes through pipes made of sturdy sheet metal (zinc-plated, inox, scratchproof enamelled, aluminum) to the high-efficiency fan or to the system’s central piping system, and from here to the filtering unit used in the specific applications. The pipes and the hood of the Evolution no-smoke are coupled together by special external articulated joints that we have patented, and a high resistance flexible pipe NO-SMOKE FLEX which allow easy and convenient movement of the arm. The Evolution no-smoke arm is also equipped with a rotary bearing which enables rotation through even 360° if installed on its special stand.
