IPR-SNSL access door are preinstalled in the round duct coupling.
Due to such combination mounting of access doors in diameters
from 80 to 800 mm becomes ultra-quick. There is no need to
cut-out the hole , place the doors and tighten the screws - it is all
done during production. It’s an ideal solution for fire damper
inspection purposes. The male coupling has laser cut edges ideally
matched to the access door. Access door can be install, for example,
next to fire damper to enable the fire damper inspection without
isassembly of the installation.
