Diversitech AF6 Duct Booster Fan 240 Cfm 6 Inch

Product Description

The DIVERSITECH AF6 is a duct booster fan designed to increase airflow in 6-inch duct runs where conditioned air delivery is insufficient. Rated at 240 CFM and 37 watts, it operates on 120 VAC and fits inline within standard round duct systems. The unit features a metal housing for durability and a permanently lubricated motor that eliminates routine bearing maintenance. A one-use thermal fuse provides overtemperature protection. Licensed HVAC technicians typically install this fan as part of a balancing solution for residential forced-air systems where specific branches receive inadequate airflow.

This booster fan is suited for residential HVAC applications where a 6-inch duct branch delivers insufficient airflow to a room or zone. Common install scenarios include extended duct runs, rooms added to an existing system, or branches with high static pressure loss. The 240 CFM output and compact inline design make it a practical fit for attic, crawlspace, or wall-cavity duct installations where a low-wattage fan can meaningfully improve distribution balance without requiring major duct modification.

Key Features

• 240 CFM airflow rating improves delivery in undersupplied 6-inch duct branches
• 37-watt, 120 VAC motor keeps installation wiring straightforward
• Metal housing provides structural durability in attic and crawlspace environments
• Permanently lubricated motor requires no routine maintenance
• One-use thermal fuse offers overtemperature protection

Compatibility

Designed as an inline booster fan for standard 6-inch round duct systems in residential forced-air HVAC applications.

Installation Notes

Installation is performed by a licensed HVAC technician. Disconnect and lock out power to the air handler and any associated circuits before beginning work. Verify the duct diameter, confirm 120 VAC power availability at the install location, and check that the fan orientation matches the airflow direction marked on the housing. Local mechanical codes and NEC requirements govern low-voltage wiring and equipment installation.
