Product Description
The Duct Blaster® Fan Without Controller is a replacement or partial-system component for professionals who already have a compatible fan speed controller, gauge, tubing, transition plates, and other Duct Blaster accessories. Rather than purchasing a full Duct Blaster system or the fan bundle with controller, this SKU is best positioned for technicians who need to replace or add the Series B Duct Blaster fan itself.
The Duct Blaster fan is used for duct leakage diagnostics, HVAC system testing, weatherization work, and building performance verification. Official TEC specs list the fan at up to 1,550 CFM free air, with measurement capability down to 10 CFM with Ring 3 and 2.4 CFM with optional Ring 4 when used with the appropriate gauge and accessories. This product should be listed clearly as controller not included so buyers understand it is not a complete Duct Blaster system.
