The Wacker Neuson Air Duct is a genuine OEM component designed for the Arctic Bear HD series indirect mobile air heaters, covering both the natural gas and diesel variants. As a direct factory replacement, this air duct installs exactly as the original, maintaining the correct airflow path through the heater assembly. Wacker Neuson OEM parts are manufactured to the same specifications as the components fitted at the factory, ensuring consistent performance in demanding job site heating applications. Confirm your model number against the Arctic Bear HD (natural gas) and Arctic Bear HD (diesel) to ensure correct fitment before ordering.
Key Features
- Genuine OEM Construction — Formed to exact factory dimensions, ensuring the duct maintains the designed airflow volume and direction through the Arctic Bear HD heater unit.
- Direct Replacement Fit — Matches the original mounting points and duct geometry, allowing straightforward installation without cutting, bending, or adapting.
- Broad Arctic Bear HD Compatibility — Fits both the diesel (5000620197) and natural gas (5000620199) variants of the Arctic Bear HD indirect mobile air heater series.
- Sustained Heating Output — A correctly sealed and intact air duct channels combustion-heated air efficiently to the output; a cracked or collapsed duct causes uneven heat distribution and reduced output capacity.
- Combustion System Integrity — In indirect-fired heaters, proper air duct routing keeps combustion gases separated from delivered air — making duct condition a critical safety consideration in occupied or enclosed work areas.
The air duct in an indirect-fired heater channels the heated air produced by the heat exchanger and directs it toward the discharge outlet, ensuring warm air reaches the target area efficiently. Because indirect heaters keep combustion gases isolated from the delivered airstream, the integrity of the duct is essential — any breach, collapse, or disconnection can disrupt airflow, reduce heating performance, and compromise the separation that makes indirect heaters safe for use in occupied spaces. A worn or damaged duct should be replaced promptly to restore full heating capacity and maintain proper operation of the Arctic Bear HD unit.
