OGMIE FlexDuct flexible air duct upgrade kit for diesel heaters

FlexDuct: Flexible Diesel Heater Ducting for Camper Vans

A diesel heater may fit neatly beneath a seat or inside a storage compartment, but the warm air outlet does not always end up where you want it. In a camper van, motorhome or truck cab, a short or awkward duct can make the final layout harder to organise.

The OGMIE® FlexDuct Air Duct Upgrade Kit gives you more flexibility when planning that warm air route. With an expandable duct reaching up to 150cm and a 360° adjustable outlet connector, it is a practical option for owners who want a tidier, more adjustable heater setup.

More reach for the layout you actually have

Every camper van conversion is different. The heater position, seating area and available storage space all affect where the duct can run. A length that works in one vehicle may be inconvenient in another.

FlexDuct extends up to 150cm (approximately 59 inches), giving you room to plan a route between your heater's warm air outlet and your preferred outlet position. Its expandable design lets you adjust the length to suit the available space, rather than arranging your interior around a short duct.

You do not have to use the full extension. Choose a route that suits your installation and stays within your heater manufacturer's ducting guidance.

Adjust the direction of the warm air

Positioning an outlet is only part of the job. You may also want to change the direction of the air once the duct is in place.

The included 360° adjustable air outlet connector gives you a way to adjust the outlet direction. This can be useful when you are deciding how to arrange warm air delivery around a seating area or another part of a compact interior.

For a van that serves as both a workspace and a place to relax, that adjustment offers a useful degree of control over the setup.

A straightforward kit for a cleaner finish

The FlexDuct kit contains two components:

  • 1 × flexible air duct
  • 1 × air outlet connector

The silver duct uses an upgraded aluminium foil construction. Its flexible, expandable design helps you arrange the warm air route more neatly around the space available.

If your current duct is awkward to position, or you are planning a new installation, FlexDuct is worth considering as part of the layout. You can see the kit and its product details here before deciding whether it suits your heater.

Check compatibility before ordering

FlexDuct is listed for most common 5kW and 8kW diesel air heater systems. However, the advertised power rating alone does not confirm a fit: the outlet connection and your particular installation also matter.

Before ordering, check your heater's warm air outlet dimensions and connection style against the kit. If you are unsure, send OGMIE your heater model and a clear photo of the outlet so we can help you check compatibility.

Use the duct for the heater's warm air system and follow your heater manufacturer's installation instructions, including any requirements for duct length, bends and clearances. The warm air duct is separate from the combustion exhaust system.

Is FlexDuct the right upgrade for you?

It is a useful option if you want:

  • An expandable warm air duct with up to 150cm of reach.
  • A 360° adjustable outlet for more convenient positioning.
  • A tidier duct layout in a camper van, motorhome or truck cab.
  • A kit containing both the duct and the outlet connector.

Start by checking the available space and your heater connection. If those match the kit, FlexDuct offers a simple way to make the warm air arrangement easier to work with.
