DUST & FUME EXTRACTION FEATURE
INTELLIGENT LEV SOLUTION provides maximum control
A complete, intelligent LEV system to tackle dust extraction and fume extraction challenges in the UK’s new High Temperature Research Centre has been installed by Western Air Ducts
T
he UK’s new High Temperature Research Centre (HTRC) has been
designed to provide the UK with world- leading R&D capabilities in investment casting. To tackle the dust extraction and fume extraction challenges these processes involve Western Air Ducts has designed and installed a complete, intelligent LEV system. Part of the Manufacturing Technology Centre campus at Coventry’s Ansty Business Park, the £60m facility is the result of joint collaboration between the University of Birmingham and Rolls Royce. The HTRC will enable production- scale and advanced manufacturing research in processes including core, wax and shell casting, chemical leaching and etching and abrasive blasting and emery dress finishing for industrial sectors including aerospace. This is a challenging proposition particularly in an R&D environment where the quality of fume extraction and dust extraction could be critical to success. One of the prime challenges for
Western Air Ducts in the design and specification of this complex LEV installation was the client’s requirement for a highly flexible solution, not only in the initial phase but to ‘future proof’ the building, allowing for later installation of a wide variety of different machines and
processes. In addition, the design and build of the facility was on an ambitious timescale so that during the initial LEV design stage, although ‘zones of activity’ had been determined the shop floor production equipment that was to be vented had not yet been selected.
Inteliair can be installed in new or existing extraction or ventilation systems and significantly reduce initial capital costs
To meet this critical need for flexibility
Western Air Ducts designed a comprehensive LEV system consisting of eight independent systems each serving a particular area in the facility and equipped with the company’s patented Inteliair system to provide maximum control and energy efficiency.
VENT TO ATMOSPHERE SUCTION ARMS AND HOSES
Extractability is selling vent to atmosphere (VTA) systems as packages comprising suction arms, cranes and hoses. These extract welding fumes and each arm has a hood installed at the tip of every suction element to ensure efficient extraction and capture the fumes at the point of source. Suction arms can be purchased with external and tubed mechanisms
which can be used on extraction applications other than welding. Arms are available for wall or ceiling attachment or connected directly
to the filter unit. Fully self-supporting, arm lengths and fans of varying capabilities are available for extracting high amounts of welding fume. Articulated arms of 2, 3 and 4 metres can be connected to individual fans or central suction and filter systems. These are supplied with a wall bracket, 0.75kw fan of 1ph or 3ph and a fan to duct adaptor. For a large area you can order an arm of 5 or 6 metres with 1.1kw 1/3ph fan or 7 or 8 metres with 1.5kw 1/3ph fan. Telescopic suction arms designed for workplaces with limited headspace are suitable for extracting pollutants produced by fixed welding benches and stretch from 1.2m to 2.06m.

OPTIMISING EXTRACTION EFFICIENCY Integration of a PLC into the air control system optimises the efficiency of dust and fume extraction and ventilation systems by continuously monitoring demand then regulating the extraction or supply of air in accord with that demand – providing potential energy cost savings of over 40%. Inteliair simultaneously reduces operating costs, lowers carbon footprint and improves air quality. Inteliair can be installed in new or existing extraction or ventilation systems and significantly reduce initial capital costs through the ability to accurately size systems based on actual usage. In addition, it can be configured to enable remote access to monitor current and past performance while providing override control if required, reducing reliance on manual intervention. Traditional LEV systems are not able to react to actual demand being simply either ‘on’ or ‘off’, resulting in low operational efficiency, high energy costs and consequent environmental impact – issues which were overcome by the Western Air Ducts solution. Although the Inteliair system can be retrofitted, because in this case it was specified from the outset the HTRC system could be accurately sized based on actual usage (as opposed to the total number of positions), resulting in a reduction in initial capital equipment cost. “We are delighted to have won this prestigious contract which was awarded after extensive discussion with the client as with such a complex project it was vital that the selected supplier would be able to work in close partnership with the client,” explains MD Chris Lintern.
