ATEX-Certified Explosion Proof Confined Space Ventilation Fan
This single-phase explosion-proof ventilation system is engineered for high-risk environments requiring spark-free operation in flammable gas/dust zones (e.g., methane, hydrogen, VOCs). Featuring a die-cast aluminum alloy body and copper inner cylinder, it ensures zero ignition risks during startup, operation, and shutdown. Ideal for rapid gas displacement in confined spaces like paint storage tanks, ship compartments, and underground pipelines, it delivers adjustable airflow (2000-3000 CFM) with IP65 protection for humid/dusty conditions. it meets mandatory safety standards for mining, chemical, and marine industries.
