Allegro 9538-25 Axial Blower Kit 900 Cfm Explosion Proof

Product Description

The ALLEGRO 9538-25 is an AC-powered axial blower kit rated at 900 CFM, designed for ventilating confined spaces, manholes, vaults, tanks, and similar hazardous or enclosed work areas. The kit runs on 115 volts and produces 0.33 horsepower, moving air through an 8-inch inlet and 8-inch outlet. The blower canister is constructed from polyethylene for durability in demanding field conditions. ETL certification and an explosion-proof rating make this unit suitable for environments where flammable vapors or gases may be present. Licensed tradespeople and safety personnel working in confined-space entry operations rely on this type of equipment to maintain breathable air and meet regulatory ventilation requirements.

This blower kit is suited for residential, commercial, and industrial confined-space ventilation applications. Typical installations include utility vaults, sewer manholes, storage tanks, and construction excavations where fresh-air supply or exhaust ventilation is required before and during worker entry. The kit includes the blower with canister and 25 feet of vinyl and polyester ducting, allowing technicians to direct airflow from a safe exterior location into the confined space without additional duct purchase.

Installation Notes

Installation and operation of confined-space ventilation equipment is typically performed by safety personnel or licensed tradespeople in accordance with OSHA confined-space entry regulations and applicable site safety plans. Ensure the power source is de-energized before connecting or disconnecting the blower. Position the blower and ducting to provide positive-pressure fresh-air supply or negative-pressure exhaust as required by the entry permit. Inspect ducting for kinks or damage before each use to maintain rated airflow.
