Six-Inch Aluminium Intake Vent Cap

The Field Controls IAH-6 intake vent cap is built for six-inch ductwork in commercial heating systems. Its aluminium construction resists corrosion while covering the duct termination. Rough-in dimensions call for a six-and-one-quarter-inch opening to seat the cap correctly. This component suits contractors finishing fresh-air or exhaust runs on rooftop or sidewall penetrations.

Fits 6 in Duct — 7 7/8 in Height

The cap slides over a six-inch duct and secures to the surrounding structure, so installers need compatible fasteners and sealant rated for the application. It frees the duct end from rain, debris and back-drafts without adding moving parts that require maintenance. The aluminium finish blends with metal roofing and siding. Builders needing a different duct diameter or a powered damper must select another model.

Questions about this item

What is the maximum sustained airflow the 6-inch aluminium cap can pass before restriction becomes the limiting factor?

The cap fits a 6-inch duct with a 6-1/4-inch rough-in opening and measures 7-7/8 inches high by 7-3/4 inches wide, so the practical airflow limit is set by the duct size and louver free area rather than the cap itself.

How much heat does the aluminium-and-steel construction radiate when the vent runs continuously in a commercial heating system?

The aluminium finish on steel reflects radiant heat and the open louver design allows continuous airflow, so the cap remains close to supply-air temperature and adds negligible heat to the space during all-day operation.
