Optional Extras

Insulated Exhaust Duct

This new insulated exhaust duct reduces the duct diameter from 17" (43cm) down to 12" (30cm) thereby making it easier to handle. Being 2.8metres long, it can either be ducted out of a window or vertically up into a ceiling void. The duct is also insulated which improves the cooling efficiency because heat is not being put back into the room/area.

The open end (12" diam) has a velcro cuff and this enables easy and efficient fitting of our 3 metre extension lengths which also have velcro cuffs. Loops are fitted to both reducer duct and extensions should support be neccessary.
