The Coral EVOLUTION NO-SMOKE ATEX fume extraction arms are designed to extract hazardous pollutants at the source and move them towards specific filtering systems in potentially explosive atmospheres.

The construction of our Coral EVOLUTION NO-SMOKE ATEX arms use specific materials of construction to guarantee a proper ground connection and dissipate the static electric energy generated by the air flow in the pipes. The Coral EVOLUTION NO-SMOKE ATEX arm is suitable to be used in zones that are classified as potentially hazardous.

Working principle

Contaminated air is captured by the fully adjustable hood and exhausted through scratch-resistant enamel coated aluminum piping. Contaminants may be exhausted to a central filtration system or, with an optional high-efficiency fan, to the atmosphere, depending upon regulations.

The body and hood of Coral EVOLUTION NO-SMOKE arm is coupled together by a special, patented external joint and support design that allows for easy and convenient movement.

360° rotation

Coral EVOLUTION NO-SMOKE arm base is equipped with a custom rotary bearing unique to only Coral which enables a full 360º rotation to optimize usability. This patented external joint design not only offers easier operator adjustability of the arm but also results in a lower static resistance to facilitate improved contaminant capture and removal. The improved performance realized by this quality construction results in lower operating costs, less operating noise, and improved air quality for the operator at the workstation. Overall, this unique design enables the arm to outperform other arms available on the market.

Optional Construction

On request we manufacture Coral EVOLUTION NO-SMOKE ATEX arm in AISI 316 stainless steel which is suitable for the food industry, pharmaceutical and chemical applications.
