Dust Extraction Systems · New Zealand Wide

A well designed dust extraction system will transform your workplace.

Investment in a properly engineered system pays for itself — with healthier staff, longer-lasting equipment and a clean, compliant workplace. We design, specify and install custom systems for woodworking, metalworking, food processing and education sectors — using globally proven, tested products, not one-off fabrications.

Industries we serve

Custom systems for the workshops that need them most

Every workplace is different. We design from your machines and processes — not a catalogue.

Woodworking & Joinery

Low-cost systems that can be expanded as your business grows. NZ Duct offer proven, tested units for fine dust exposure at 1/3 of the NZ limits.

Metalworking & Welding

Spark arrestors, fume arms, welding benches, downdraft tables and toxic-particle filtration to keep welders breathing clean air.

Food Processing

Hygienic, washdown-ready capture systems with explosion protection for grain, flour and combustible dusts — including products for packing and tipping operations.

Schools & Education

Workshop extraction systems that meet Ministry of Education guidelines — with unique explosion relief systems (Vertical Flameless Venting) that surpass MoE guidelines for safer students and easy maintenance.

Why source capture

Grab the dust where it’s created — before it spreads.

Ambient extraction (like roof fans) sucks up dust after it has already filled the room, settled on equipment and reached the people working there. Source capture intercepts it at the cutter, the grinder, the welding torch — the moment it’s generated.

  • Healthier staff. Lower respiratory exposure and a visibly cleaner workplace.
  • Lower maintenance. Bearings, electronics and finished products last longer.
  • Compliance ready. Designed to meet WorkSafe, ATEX and MoE expectations.
  • System balanced. Right airflow at every machine — not just the closest one.
