ITM Ducting, 5 Metre to Suit 300mm Ventilator 

The ITM TPV300DUCT is 5 metres of expandable, flexible ducting sized to suit ITM's 300mm portable ventilator (TPV300), giving you the reach to direct airflow — extraction or fresh air supply — well away from a confined work area. Expandable ducting like this collapses flat for storage and pulls out to full length on demand, making it a practical match for a portable fan that gets moved from job to job rather than mounted in one fixed spot.

Paired with the TPV300 ventilator, it's suited to general workshop and confined-space ventilation: clearing background fume and heat build-up, or pushing fresh air into an enclosed area such as a tank, pit, or bay. It's worth being clear on what this product is and isn't: it's general dilution/displacement ducting for a portable axial fan, not a source-capture local exhaust ventilation (LEV) arm. For welding fume specifically, AS/NZS ISO 21904 and the WES-to-WEL transition (effective 1 December 2026) call for fume to be captured at the source — that's the job of an extraction arm with a hood positioned near the arc, not general area ventilation. A TPV300DUCT setup is a good complement to source-capture LEV in a workshop, supporting overall air movement, but shouldn't be relied on as the primary fume control for welding tasks.

Specifications

Ducting is also available to suit ITM's 200mm, 400mm, 500mm, and 600mm ventilators — contact QWS if the TPV300 isn't the right diameter for your setup.

Frequently Asked Questions

What fan does the TPV300DUCT fit? It's sized to suit ITM's 300mm portable ventilator (TPV300), including as a replacement or spare for the TPV300SET ventilator set, which includes this ducting as standard.

Can I use this ducting for welding fume extraction? It can help move general air and fume out of a workshop or confined space when paired with the 300mm ventilator, but it's not a substitute for a purpose-built local exhaust ventilation (LEV) extraction arm at the welding arc. For compliance with AS/NZS ISO 21904 and the WES-to-WEL exposure limits, source-capture extraction should remain the primary control.

Is the ducting expandable or fixed-length? Expandable — it collapses for compact storage and extends to its full 5m run when in use.

What else do I need to run this ducting? An ITM 300mm portable ventilator (TPV300). If you don't already have one, the TPV300SET bundles the fan and this ducting together.
