A welding solution: Time to move to improve staff’s air quality

Family-owned Melrose Kiwi Concept Chairs has supplied mobility products for more than 25 years, and is a major brand for wheelchairs in New Zealand and Australia.

The company’s Christchurch-based manufacturing plant employs six full time welders, with other production staff, needing effective fume extraction.

As the company has grown, Melrose decided to centralise its extraction system but wanted the flexibility for each extraction point to cover two bays. NZ Duct+Flex visited the site to see how best to achieve effective fume extraction to fit with the workshop’s activity.

NZ Duct+Flex’s own installation team has installed hundreds of the blue and yellow European sourced fume arms for welding fumes, and here, six 160mm/4m reach arms were used, with a mobile FumeCube, for specialist work carried out in different parts of the workshop.

“Our suppliers have been around for decades and their products have been tried and tested and enhanced over this time,” says sales manager, Geoff Ebdon. “All our fume solutions are also sourced from two major European suppliers ensuring value for money and products that actually do the job.”

Annette Melrose confirmed that all is running really well, with greatly improved air quality for staff.

The fume arm range is very robust with metal tube arms and hoods, external hinging meaning the debris being exhausted cannot cause the hinging to wear or become jammed (low maintenance).

All fume arms are in stock, available for immediate delivery from 75mm dia/1m up to 160mm dia/4m reach. Extraction arms can be driven by a fume fan, or for larger workshops with a centralised system, a JKF fan can be used.

For mobile solutions there are one or two arm fume cube units – a solid but compact mobile unit with pre-mesh filter for sparks, pull out cartridge filter and fan all in one unit.
