The Allegro is a portable 8-inch axial AC air blower with a 1/3 HP motor and an 831 CFM free-air rating. Its compact polyethylene housing supports ventilation, fresh-air direction and non-hazardous air-exhaust tasks in industrial and commercial work areas. This EA494 sellable configuration is the blower only; compatible ducting and a canister are sold separately.
Airflow Under Defined Conditions
Allegro rates the blower at 831 CFM in free air. With 15 feet of 8-inch ducting, the manufacturer lists 709 CFM with one 90-degree bend and 586 CFM with two 90-degree bends. These figures describe different system conditions and should not be treated as interchangeable.
Compact, Portable Construction
The 17 lb blower has a carry handle moulded into its polyethylene housing for practical movement between work areas. Allegro describes the housing as lightweight and resistant to corrosion, ultraviolet exposure and chemicals. A nine-blade polypropylene fan, powder-coated steel grille and protected bottom electrical enclosure support routine portable use.
AC Power and Optional Air Direction
The single-phase motor is rated for 115–230V AC at 50/60 Hz and includes an on/off rocker switch and 10-foot cord. The blower can operate alone or connect to compatible canister and ducting systems to direct intake or output airflow; those accessories are not included with model 9533.
Important: Model 9533 is not the 9538 explosion-proof blower. Do not use this product in flammable atmospheres or treat its ventilation classification as hazardous-location approval. Suitability for any confined-space job must be determined through the applicable worksite assessment and safety requirements.
