Running the Autoterm Air 9D (8kW) and need to connect your hot air outlet or inlet to 90mm ducting? This is the adapter you need.
The Air 9D is a big heater — it puts out serious heat and uses 100mm air connections by default. But 90mm ducting is far more common in van and camper builds, and Autoterm officially permits this reduction, so you're not compromising the system when you use it correctly.
Made from durable PA6 glass-filled plastic, it handles the sustained heat and airflow of the 9D without warping or degrading. The stepped design gives a secure, rattle-free fit into your 90mm pipe or Y-junction.
Specifications:
- Part number: ASSY DE034
- Inlet diameter: 100mm (heater side)
- Outlet diameter: 90mm (ducting side)
- Material: PA6 glass-filled plastic
- Compatibility: Autoterm Air 9D (8kW) — also known as Planar 9D
A simple, essential part for a clean, leak-free hot air distribution run.
