Axial Duct Booster Sleeve 15-1/2 In.

This in-line axial duct booster is designed to increase airflow in 14-inch diameter ducting for general-purpose ventilation. It suits installers and facility managers needing a straightforward, single-speed solution to overcome static-pressure losses in straight duct runs.

200 CFM airflow at 0.000 in SP

The unit delivers 200 cfm at zero static pressure through a 14-inch duct connection. Its 29.8 W motor runs at 1,500 RPM and is rated for inlet air temperatures up to 150 degrees F, so it handles warm-air circulation but provides no speed control for variable demand.

External junction box for easy wiring included

The bundled external junction box simplifies electrical connections at 120V AC single-phase power. No high-efficiency motor, variable-speed controller, or mounting hardware beyond the galvanized-steel housing is supplied, so installers must source any additional controls or supports separately.

Questions about this item

Will the 14 in duct diameter match my existing 14 in round ductwork?

Yes, the booster sleeve is built for a 14 in duct diameter so it fits directly into standard 14 in round duct runs without adapters.

How can I confirm the fan is moving air at the rated 200 cfm after installation?

With the duct sealed and the fan running at 1,500 RPM you should feel strong, steady airflow at the register; a handheld anemometer at the grille will read close to 200 cfm at 0.000 in SP.

Does the package include mounting hardware or do I need to supply screws and duct tape?

The unit ships with an external junction box for wiring; mounting brackets, screws, foil tape or clamps for the 14 in duct connections are not included and must be purchased separately.
