Being inflatable with Ventura's Advanced Air System,  you will find Trinus W400 incredibly easy to put up because the system comes with patented coupling modules to ensure proper attachment and easy adjustment and replacement. Of course, a double air pump is supplied with the awning as standard.  

Trinus will give you the freedom and flexibility you require. All the front and side panels are removable, so you can alternate the appearance and ventilation of your awning depending on the weather and your preferences. Speaking of ventilation, the two doors (one in each side panel) is supplied with a mosquito net. Although you may value ventilation, you may not like draughts, which is why you are supplied with a draught excluder with Air Tube as standard; this device will allow you to connect your Trinus to your caravan effortlessly, creating a perfect seal. You are also supplied with a veranda pole as standard, which you can use to fold down one of your front panels halfway down if you wish. 

Not only the large living area will make this a comfortable place to be; the large and clear windows in front and side panels will allow a plentiful supply of natural light to enter the awning. On top of that, the light panels in the roof will allow even the tiniest sunrays to shine on you.  On occasions when you want to keep the insides dim and cosy, the beautiful Luxor white curtains (supplied as standard) hanging from the curtain poles can be shut easily, so you can feel like home. In the interior, you will fit an attachment for LED strips if you want that lovely Isabella glow (LED strips not included).

Ventura cares for the appearance and design of their awnings. This is why Trinus comes in the following beautiful colourway: Ventura Air Trinus W400 Colours

Moreover, the guy straps are reflective and in the corners, they are kept neatly in pockets in the fabric. These don't only look nice but also secure the awning. What also secures the Trinus are the aluminium rear legs and canopy fibre poles.

To promote the indoor climate in your awning, Ventura Trinus walls are made of the revolutionary IsaLite 195g/m² which is as breathable as it is waterproof. It is also remarkably light - making it perfect for touring and facilitating the set-up. Moreover, IsaLite is very easy to maintain - you can clean it easily thanks to its external coating and keep the lovely Antracite/Ice-Grey/Blue colourway last for a long time.

The roof of Ventura, on the other hand, is made with one of Isabella's finest; IsaRoof Light 240g/m² which, as the name suggests, is lightweight; hence, it is especially suitable for touring. This material is also highly breathable which helps to keep the awning interior at a comfortable and pleasant temperature thanks to the UV-resistant polyester textile it is made of, which is further treated with three layers of breathable acrylic.
