Flextraction, a supplier and manufacturer of Local Exhaust Ventilation (LEV) products, has launched a range of self-supporting Hood Positioning Devices (HPD).

The Flextractor HPD, Extended HPD, Mini HPD and Flextender HPD all incorporate new mounting brackets, hoods and hoses for the capture and extraction of industrial dusts and fumes, including hazardous and corrosive fumes at the point of source.

These HPDs have been designed to be used in a range of industrial applications, including surface grinding, welding, product tipping and drum filling, as well as food processing and all manufacturing applications where dust and fumes are emitted.

They meet HSE requirements for the correct positioning and design of LEV hoods and provide stability and accuracy in the carrying and positioning of a range of hoods in different sizes, weights and designs, including individual customised hoods plus hose combinations.

Without any internal obstructions, there is no wear, corrosion, flow restrictions or solids built up within the hoses.

The twin-support mechanism incorporates two springs to provide a greater return force than in previous models, producing a lighter and more balanced feel to the arm, especially when manipulating it into the correct extraction position.

This increased return force, as well as an increased surface area around the central pivot, enables the design of fully customised hoods to be added to the HPD.

Other features include a rear casing that is fully enclosed, giving an improved aesthetic appearance and protection against dirt ingress; a rear boom extension that gives a 270deg working radius; a 360deg rotating swivel hood that enables more accurate hood positioning; and quick-release clips that attach a range of flexible hoses such as standard PVC, FD-approved polyurethane, high-temperature, chemical and solvent-resistant as well as Atex-certified hoses.

Options include tubed, Atex-compliant and stainless-steel models, plus a fitted electronic airflow indicator.

Flextractor HPD units are suitable for standard wall or stanchion mounting, as well as upward and downward swivel, joist and ceiling mountings, and are available in five standard lengths between 1.5 and 4m.

Optional solid tubed sections in the same diameters and with flexible joints are also available to further reduce the risk of solids build up.

The Extended HPD enables a longer reach, up to a maximum 8m.

The wall- or bench-mounted mini HPD is available in three standard diameters: 75, 100 and 250mm with 1 or 1.5m reaches.

The Flextender HPD has a telescopic extraction arm giving the user a 1,200-1,650mm reach, especially useful in low-headroom or limited-space applications.

Flextractor HPDs and Flextender HPDs are available in 75, 100, 125, 150 and 200mm diameters.

A range of hoods is available in a variety of designs including bell mouth, flare, fish tail, flat screen and custom designed.

These are available in epoxy coated, stainless-steel, polypropylene and Atex versions.
