A portable blower is only half a tool once the temperature drops. The Airmaster 78966 heater attachment clips onto the front of an Airmaster portable utility blower and turns it into a 4,500 BTU portable heater, so the same unit that dries a stripped floor in summer keeps a job trailer or garage bay workable in winter. Contractors, floor-care crews and shop owners buy it because it saves carrying a second piece of equipment and it runs on the blower already in the truck.
Built for these use cases
- Warming a job trailer, garage bay or unheated work area without a second machine
- Speeding cure and dry times on coatings, paint and finishes in cool conditions
- Spot heating during winter construction punch-out and turnover work
- Basements, home gyms and storage rooms that need heat only occasionally
- Getting more months of use out of a blower that would otherwise sit idle all winter
Fit and compatibility
The 78966, catalogued by Airmaster as the HFUB11, is an accessory rather than a standalone appliance. It is built specifically for Airmaster's portable utility blower and takes its power from the blower's own side outlet, which is why it uses a short 8 inch cord instead of a full-length one. It will not clip onto a drum fan, an air mover from another manufacturer, or a blower with a different housing profile. If you do not already own the Airmaster portable utility blower, that unit is sold separately and is the prerequisite for this attachment. Check that the outlet on the side of your blower is present and functional before ordering, since older or repaired units occasionally have it disabled.

Installation and care
- Confirm the blower is unplugged before clipping the attachment onto the housing.
- Seat the clips fully on the front of the blower so the attachment cannot shift while the fan is running.
- Plug the short cord into the outlet on the side of the blower rather than into a separate receptacle.
- Run the blower first, then switch on the heater, so air is always moving across the element.
- Switch the heater off and let the blower run for a minute before shutting down, which lets the element cool under airflow.
The practical appeal of this attachment is fleet simplification. Instead of stocking separate blowers and separate heaters, a crew carries one blower and a small accessory that lives in the same case.
Frequently asked questions
What does the 78966 attach to?
It is designed for the Airmaster portable utility blower. It clips onto the front of the blower housing and plugs into the outlet on the side of the blower, so no separate power drop is required.
How much heat does it produce?
It is rated at 1,320 watts and 4,500 BTU per hour on a standard 120 volt, 60 Hz circuit at 10 amps.
Is it safe to leave running?
The attachment includes thermal protection and is CSA listed. As with any portable electric heater, it should be used on a dedicated circuit where possible, kept clear of combustibles, and not left unattended in an unoccupied space.
Can I still use the blower for air movement afterward?
Yes. The attachment removes as easily as it clips on, so the blower goes straight back to normal drying and ventilation duty.
Does it come with the blower?
No. The 78966 is the optional heater attachment only. The portable utility blower is sold separately.
