NZ Duct & Flex, stockist of New Zealand’s largest range of Fume Arm extraction system is expanding its range in October with the launch of a model 75mm in diameter with a reach of 1m.
Available in stainless or powder coated steel, the 75mm model is ideal for small bagging areas and sampling rooms, with the stainless version frequently preferred by laboratories. As with the larger models, the smaller version has easy-to-adjust dampers as standard.
“We noticed that laboratories and education-based users prefer the solid industrial-quality of Fume Arms but often, they were just too large to fit on lab benches and in small mixing rooms. This makes the new model ideal. It has industrial strength but is smaller. It folds in half and swings out of the way, up against the wall,” NZ Duct&Flex sales manager Geoff Ebdon says.
He reports that sales of Fume Arms, which the company sources direct from one of Europe’s leading manufacturers, have been increasing since they were launched in mid-2011. “By sourcing direct and buying in bulk, we are able to offer metal-tubed Fume Arms with the hinging all on the outside, at similar pricing to more basic plastic flex arms,” he says.
Hinging inside the airflow results in problems, as the hinged mechanism is degraded by the dust and debris carried up inside the arm. External hinging removes this problem but had always been more expensive.
The Fume Arm’s metal tubing is also more robust than plastic flex. It is better at standing up to hot fragments and abrasion than the cheaper plastic-covered models.
“Of course if you’re just extracting warm air, a plastic-covered arm is fine and we do offer these at a lower cost, but as soon as you start to capture particles, the external-hinged models give far fewer problems,” Mr Ebdon says.
NZ Duct&Flex currently stock the following range:
• 75mm dia. x 1.5m reach – Schools/light industrial use
• 100mm dia. x 2m reach – Light industrial/bagging points
• 125mm dia. x 3m reach – Industrial powders/light welding
• 160 mm dia. x 3m or 4m reach – Welding and general industry
Mr Ebdon says that as the government becomes more active in protecting employees in their work environments, “Fume Arms are a versatile solution to dealing with impurities in the work place especially in situations like welding, and bagging of powders. Their great advantage over a conventional hood are that they can be positioned close to the source of the dust and remove it away from the operator –and not past their face to a hood positioned above.”
NZ Duct&Flex stocks modular ducting (LipLock® system) and plastic flex, and along with matched fans can offer all the parts required for a complete system for the smallest and largest projects. It can supply a simple Fume Arm + fan + duct, or a compact mobile unit, to solve a small Health & Safety issue overnight.
