Weather Louvres

NSV update the design its high efficiency weather louvres & coalescers.

NSV weather louvres have been subjected to a performance test by a third party independent test authority (BSRIA) to BS EN 13013:2001. The results prove our designs are working better then expected and we can provide more efficient louvres and coalescers at a lower air side pressure drop.
