Airtight spigot with double lip seal now comes standard on our plenum boxes !
We developed a spigot that clearly will effect the performance and ease of use for most of our products. Starting from January 2016 all our plenum spigots between the sizes 125mm and 250mm (that is 125mm, 160mm, 200mm and 250mm) will be air tight Class D according to EN15727/EN12237.
The entire spigot can simply be taken off to save on transport costs or to help you during installation. The new design will also allow a quick removal of the optional damper, e.g. for cleaning reasons.
Probably you have some customers for this spigot as well? Or you could even use this product in your own production.
