Explosion-Proof Fire Fan Control Box

Our Explosion-Proof Fire Fan Control Box (FB-XF series) is a dedicated control solution for fire fans in explosive and hazardous locations including chemical plants, oil depots, coal mines, and facilities with flammable gas or dust atmospheres. Designed with explosion-proof enclosure construction and certified components, this box provides fan motor control, circuit protection, fire linkage, and status indication while containing any internal arc or spark within the enclosure to prevent ignition of the surrounding explosive atmosphere. The explosion-proof design meets hazardous area classification requirements, with flameproof joints and sealed cable entries ensuring safe operation in Zone 1, Zone 2, and corresponding dust hazard zones. The fire linkage function enables automatic fan activation during fire emergencies, while the manual/auto selector supports local control for maintenance. Built with robust explosion-proof enclosures and certified control components, this control box ensures reliable fire fan operation in hazardous industrial environments where standard control boxes cannot be used. The FB-XF series format offers a proven, certified structure tailored to explosion-proof fire fan requirements, making this box ideal for chemical facility fire ventilation, oil and gas hazardous area fire protection, and coal mine fire safety systems.

Yuanzhuo Electrical Equipment manufactures explosion-proof fire fan control boxes strictly to customer drawings and hazardous area specifications. Our 12,000 m² facility with five automated production lines and an annual capacity of 10,000 units supports both small and large orders. Each box undergoes 100% powered testing, including explosion-proof enclosure integrity verification and fire linkage simulation, before wooden-crate packaging. We support paid samples with a typical development cycle of about one week, and standard delivery of three weeks to one month.

Customization includes motor power rating, hazardous zone rating (gas and/or dust), explosion-proof enclosure material (cast aluminum or steel plate), control method, fire linkage input, manual/auto selector, certified component selection, cable entry configuration, enclosure dimensions, installation type, surface finish, and customer branding. We manufacture strictly to confirmed customer drawings and hazardous area specifications.

Each box is wrapped in protective film and packed in a wooden crate with internal anti-collision padding. We support FOB to a designated Chinese port and EXW. Payment: 40% deposit, 80% after pre-shipment inspection, full balance at the designated Chinese port. Currencies: USD, EUR, RMB.
