A new local exhaust ventilation was required for the TIG (Tungston Inert Gas) welding operation conducted on a daily basis at our customer’s facility, where they design and manufacture forming sets for food and pharmaceutical packaging machines.
Thirteen Impact RFF 4000/125 articulating fume extraction arms were installed to capture and control the fume at source. Each extraction arm was supplied with a 360 degree swivel type connection and fitted with a flow optimising flanged hood complete with open/close damper, providing excellent versatility.
We supplied a centralised ducted system connecting to the extraction arms using spirally wound circular hot dip galvanised prime steel ductwork, manufactured from continuous hot dip zinc coated low carbon steel manufactured to BSEN 10327: 2004 complying with HVCA DW144. The ductwork was installed at approximately 3.5-4m high and supported via Unistrut and threaded rod and appropriate brackets. The ducting terminates into an externally mounted Impact ACF -T 234H/W3 reverse jet cyclonic filtration unit fitted with G115A high efficiency filter media and 15kw centrifugal fan.
Upon completion of the installation the system was commissioned by one of our P601/P604 certified technicians and full report/documentation issued in line with HSG 258- Controlling airborne Contaminants at Work.
