Self supporting Hood Positioning Devices (HPD), including the Flextractor HPD, Extended HPD, Mini HPD and Flextender HPD from Flextraction Ltd, supplier and manufacturer of Local Exhaust Ventilation (LEV) products are available with ATEX compliant finishes or stainless steel. They are ideal for food ingredient tipping and drum filling in bakeries and all other food processing and production applications, where dust and fumes are emitted. With over 15 years of engineering design experience and computer modelling software to manufacture flexible extraction arms, Flextraction has strived to obtain the correct solution for most LEV problems. The HPD has been designed to address the deficiencies of conventional flexible extraction arms, in line with current HSE guidance, to ensure the correct design and positioning of LEV hoods. HPD’s in Stainless Steel finishes, 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.
There are no mechanics inside the flexible arms for optimised flow properties and eliminating the risk of dust being collected in any crevices and also allowing the wash through of the equipment of paramount importance in food production. Being ATEX compliant means that painted products are coated with an anti-static paint so that they can be used in hazardous area zones, which are based on the frequency and duration of where there can be an occurrence of an explosive atmosphere in which a mixture of air with dangerous substances in the form of gas, vapour, mist or combustible dust may occur in normal operations.
Features of these HPD’s include a rear casing that is fully enclosed giving an improved aesthetic appearance and protection against dirt ingress, a rear boom extension giving a 270° working radius and a new 360° rotating swivel hood enabling more accurate hood positioning, whilst quick release clips are used to attach a range of flexible hoses including ATEX certified hoses. Flextractor HPD’s 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 1,5m and 4m. The Extended HPD provides the user with the additional option of a longer reach up to a maximum 8m. The wall or bench mounted mini HPD is available in standard diameters 75mm, 100mm, 125mm, 150mm and 200mm with either a 1m or 1.5 m reach. A range of hoods is available in a wide variety of designs including bell mouth, flare, fish tail, flat screen and custom designed.
Flextraction also designs and manufactures a range of downflow extraction booths to contain dust over large areas where conventional hoods are not always sufficient, or where dust emissions can spread over a wider area, such as when scooping from tubs or bags into a weigh point in bakeries and other food production plants.

Riley Product Handling Ltd in Derby is a manufacturer of bakery systems used predominantly in biscuit and cracker production. Their equipment links the exit of an oven with wrapping machines, sorting products into the right numbers of lanes and presenting the products at the correct angle and pressure.
When Riley Product Handling, which exports up to 80% of its products, took the strategic decision to dispense with out sourcing their MIG, TIG and MMA welding fabrication, they needed the appropriate equipment to undertake such work. Initially they used a portable fume extraction system with two extraction arms, before they decided to go for a fixed system with flexible extraction arms extracting fumes externally via a filter unit to save on space with no clutter and a much reduced noise level.
Tim Wilding, Engineering Manager at Riley Product Handling contacted Simon Plaister at Foster Industrial, his local welding equipment distributor in nearby Nottingham for advice. Foster Industrial is a distributor for flextraction Ltd, supplier and manufacturer of local Exhaust Ventilation (LEV) products and was asked as one of three bidders to submit a quotation.
The flextraction system was selected on the basis of design, price and communications. It comprised 5 x extended HPDs (Hood Positioning Devices) and 2 x 2m standard HPDs. Each extended HPD consisted of a 3m standard extraction arm and a 3m extension. All seven HPDs were equipped with epoxy painted black 150mm diameter flared hoods and assembled complete with wall mounting, control damper and with no internal components.
A TEKA 400V/50Hz ‘Filtercube 4H-4000’ centralised filter unit with a dust extraction efficiency of >99% to meet BGIA certification DIN EN ISO 15012-1 (Health and Safety in welding and allied processes) was used. Dedusting of the filter cartridges is done using a fully automated microprocessor Pulse Control. The ducting used in the project was manufactured from spiral galvanised sheet steel and was installed with inspection doors, flexible hose connections and supporting brackets.
The extended HPDs are used for welding, whilst the standard HPDs which are linked to a wet pre-separator system before joining the main ductwork, are used for grinding operations.
Tim Wilding said: “We fabricate our products using 1mm – 6mm mild steel and stainless steel, occasionally up to 10mm. Typical components are frames for conveyors and machines, tracks for vibratory conveyors, guides and guards. The main welding process we use is TIG welding, however MMA welding is used for high strength welds in vibratory troughs, whilst MIG welding is used on frameworks where large fillet welds are required.
We decided on the flextraction system because with ever increasing Health and Safety legislation, we thought it prudent to install a system that did not just meet legalisation but would be future proof. As it was, the installation was completed in a week, which was to the timescale quoted and compared to our existing portable units the fabricators’ working environments are significantly improved with reduced noise levels. The length and type of HPD are light in weight and are quick and easy to locate for the point of extraction where ever it is needed, which is exactly what we wanted.”
Lee Darton General Manager Products at Flextraction said: “Our fume extraction system is equipped with gate valves so it can be balanced. During commissioning, the system was tuned to achieve the legislative face velocities at each point of extraction, which was easily achieved as the system is capable of 8,000m3/h over 6 extraction points. In fact we were able to reduce the velocities to meet current legislative levels to reduce noise.”
Tim Wilding continued; “The system is inspected every week by the shop floor person responsible and there have been no issues. We encourage individuals to look after their equipment and report any faults, all of which are logged in a book, which is used as part of a safe contractor qualification.”
Overall the system was installed successfully and on time, meets all the extraction requirements of Riley Product Handling and the workshop environment has greatly improved.

When the Severn Valley Railway (SVR) in Shropshire, needed support with their welding fume problems, they turned to, Flextraction, who supplied their latest TEKA mobile cartridge filter welding fume extractor - Strongmaster UPF.
It has a welded steel body housing a high efficiency filter cartridge, 3,000 m3/hr fan unit and 1.1kW motor. A filter full indicator is standard, which tells the user when to clean the filter cartridge. This is carried out quickly and safely by the unique way TEKA has designed the safe clean chamber. The cartridge filter also enables the unit to be also used for grinding.
The SVR application was unusual having its roots at the heart of the steam age - the steam engine firebox. One area in particular, repairing the fireboxes, was creating a problem with fumes and dust. Both MIG and TIG welding processes operating at over 400 amps, are used on a range of materials. The main concern was the firebox lining, which was 16mm triple dioxide phosphorous arsenic copper. SVR's welder David Howell often has to climb into the firebox to cut away and replace panels. David said, "The fumes were considerable and we needed a flexible and mobile solution that could reach the areas of weld, wherever I was, on or even in the firebox."
Due to the workshop environment and the high degree of filtration required, there was a need for a long reach and flexible extraction arm. The stability of the TEKA system enabled Flextraction to fit a 4m long self-supporting arm allowing David to reach right into the firebox.
David and his colleagues have noticed a considerable difference in the workshop atmosphere since purchasing the unit. David continued, "The workshop used to fill up with fumes and our face masks became very dirty. This no longer happens and we are delighted with the TEKA Strongmaster. I can be welding anywhere on the railway and as the extraction equipment is so mobile I am able to take with me, where ever I go." Non welders and support staff within the workshop also commented how they are no longer exposed to the fumes created by the welding and grinding operations.
Severn Valley Railway dates back decades to the Hanbury to Shrewsbury line via Bridgnorth. When it was broken up by British Rail, a society was formed, uncannily at the local pub at one end of the line, and they saved this beautiful stretch of historical railway.
The society has a large and impressive range of steam engines and a continuous programme of repairs, maintenance and overhauls is carried out at their extensive Bridgnorth workshops.
