The ATEX certified Evolution No Smoke self supporting extraction arm, providing possibly the best industrial extraction solution, has been launched by QD/Coral. Complete removal of welding smoke, gas, vapours, aerosol, oil fumes and dusts has until now been difficult, particularly if customers require ATEX certified products, Evolution has changed the rules. It has been designed and built in full compliance with current laws relating to the work-place safety and the successful removal of hazardous fumes and polluting substances from the working environment.

Evolution extraction systems are available in a range of sizes from andOslash;100 - andOslash;200 with a 2.1 m - 4.2 m metre reach capability, and are ideally suited for environments that are highly corrosive.

Polluted air is drawn in through the jointed hood and passes through pipes made of sturdy sheet metal (zinc-plated, stainless steel, scratchproof enamelled mild steel, aluminium) to a high-efficiency fan or to a central piping system, and then onto the filtering unit used in the specific applications.

The pipes and the hood of the Evolution are coupled together by special external articulated joints and a low resistance flexible no-smoke pipe, allows easy and convenient movement of the arm.

Rotary bearings within the arms enable their rotation through 360o if installed on a special stand.

The flow of polluted air that passes through the suction duct created by the arm, is not therefore hindered by the internal joints or articulations and because all major mechanisms are externally mounted the suction capability is maximised, leading to reduced energy costs.

- 2 - Due to the reduced length of the hose used in the elbows, load losses are far lower than with other similar systems on the market.

Less load loss means: lower fan power, hence energy saving, lower air flow speed hence less noise.

Different working positions and environments demand varied performance.

The Evolution suction arm represents the ideal solution to this drawback as, thanks to the built-in adjustment shutter, it is possible to meter the amount of air to be entrained.

It is also possible to filter the polluted air using special optional filters supplied as accessories and recycle it back to the environment completely free of pollutants.

The total flexibility of the arm is combined with robust construction which eliminates the risk of damage when users attempt to bend the arm when using it in confined situations.

It is easily adapted to any fixed or mobile system and is self adjusting.

Commenting on the new product, Stuart Shepherd Marketing Manager of QD/Coral said: 'ATEX certified extractors are a positive addition to our range, and because of Evolution's sturdy design, we predict less maintenance, less repairs, and a lot less down time and process interruption for your money.'
