Types of Chemical Storage Ventilation
Passive Chemical Storage Ventilation
U.S. Chemical Storage passive vents allow a steady flow of air in and out of your chemical storage building with no mechanical assistance. Passive ventilation creates a natural air flow and is best used with chemicals that do not produce hazardous vapors or debris. Vent openings include screens and louvers to prevent unwanted animal entry and to provide weather resistance.
Explosion Proof Mechanical Ventilation
Explosion proof forced ventilation is necessary for chemicals that produce flammable or explosive fumes as well as for storage buildings used for mixing and dispensing flammables. These mechanical vents perform a minimum of six air changes per hour at a rate of no less than 1 cubic foot/min.
Our explosion proof mechanical vents isolate the motor of the ventilation system from contaminants in the building to prevent an explosion.
Non-Explosion Proof Mechanical Ventilation
U.S. Chemical Storage supplies a non-explosion proof mechanical ventilation for use when storing non-explosive or non-flammable chemical inventory. Ventilation fans maintain a 1 CFM/SQFT air flow and perform a minimum of six air changes per hour.

Fume Snorkel Extractor Arm
The optional fume snorkel extractor arm consists of an anti-static explosion proof exhaust fan with a three joint telescopic extractor arm. The exhaust fan is mounted on roof, and the telescopic extractor arm attaches to the side of the ceiling column approximately 12 inches from the ceiling. A reducer attaches the arm to the main duct. The arm ranges approximately 3.5 to 7 feet horizontally and vertically.
