New: Fire Stop Sound Attenuator Assembly
Due to increasing regulations regarding fire and smoke protection within the duct work of air systems, SpacePak has developed a fire rated sound attenuator. The fire rated attenuators are manufactured at our factory in North Carolina using a 3M Fire Barrier rated up to 3 hours by UL and tested in accordance with ASTM E 814 (UL 1479). The fire barriers are contained within the attenuator and when installed
with the terminator plate, will be affixed directly to the ceiling. For full details, please refer to the 3M Product Data sheet and the installation instructions below.

Installation Instructions

The fire stop sound attenuators can be ordered as kits of 2 or 5 pieces, or ordered individually. Spacepak will not be offering the fire stops as individual components to be installed in the field, as this may compromise the integrity of the component. They must be ordered as a complete attenuator assembly. 

The installation kits include: Fire Stop Sound Attenuator w/ kwik connects, kwik connects, balancing orifice set, terminator plates w/ hardware, and winter shut offs.
