The Wolf Safety Hazardous Area Ventilation Series (United Kingdom) comprises high-performance portable explosion-proof fans, industrial blowers, and compressed air-driven Venturi Air Movers specifically certified for hazardous, flammable, and confined workspace environments (Zone 1, Zone 2, Zone 21, Zone 22). Engineered with high-strength anti-static conductive polyethylene composite housings, these units entirely mitigate static discharge hazards. The portfolio accommodates both dual-voltage electric power inputs (115V / 230V) and 100% pneumatic air-driven configurations for environments where electric cables cannot be safely routed.
