FasNSeal® 80/90

FasNSeal® 80/90 is a unique, patent pending system that exhausts 90+ condensing appliances with Type B atmospheric units within the same vent.

Using your pre-existing common vent, our cap improves the operation of both the remaining atmospheric appliances, and the new condensing unit, while not disturbing finished space during installation.

Finally a solution when you need to deal with narrow lot lines, clearance to window and door openings or when side wall venting just isn’t practical.
