Westfield Universal Air Annex  – Extra Space, Storage & Weather Protection

The Westfield Universal Air Annex is a premium, tall air annex designed to add valuable extra space and storage to your awning setup. This universal annex is specifically engineered to fit the Westfield Pluto and Vega air awnings, while also being compatible with the Omega and Aries models.

Constructed from lightweight HydraDore SL Pro fabric, the annex is easy to handle, quick to pitch, and fast drying, making it ideal for touring and short stays as well as longer trips. Despite its low weight, the fabric delivers outstanding durability and a hydrostatic head of 4000 mm, far exceeding the standard for fully waterproof materials. This ensures excellent protection against rain and challenging weather conditions.

Its taller roofline provides increased headroom, creating a more open and airy feel inside. With a large rear access door and toggle-in panel included, the Westfield Universal Air Annex offers flexibility, convenience, and comfort. It can be fitted to either side of your awning—or even both sides—making it a versatile solution for expanding your living space whenever needed.
