The Allegro is a portable 12-inch axial air blower powered by a 1 HP motor and rated for 1842 CFM in free air. Its compact polyethylene housing supports ventilation, fresh-air direction and non-hazardous air-exhaust tasks in industrial and commercial work areas. This EB261 sellable configuration is the blower only; ducting and a storage canister are not included.
High-Volume Free-Air Performance
The 1842 CFM figure is the manufacturer’s free-air rating. Actual airflow changes when ducting, bends or other restrictions add resistance. Allegro’s technical sheet lists 1004 CFM with 15 feet of 12-inch ducting and one 90-degree bend, and 933 CFM with the same ducting and two 90-degree bends.
Portable, Resistant Polyethylene Housing
A carry handle moulded into the housing makes the 28 lb blower easier to move between work areas. The safety-orange polyethylene construction is described by Allegro as lightweight and resistant to corrosion, ultraviolet exposure and chemicals, helping the housing suit routine transport and use in demanding non-hazardous environments.
Flexible AC Motor Specifications
The single-phase motor is rated for 115–230V AC at 50/60 Hz and includes a built-in on/off rocker switch and 13-foot cord. The 9543 is non-explosion-proof: it is not certified for hazardous locations or flammable atmospheres. Suitability for any confined-space job must be determined through the applicable worksite assessment and safety requirements.
