Where it is used
Cooling (heat relief) in premises containing explosive gas mixtures of Class A or B combustible gases with air, temperature classes T1–T4, in Zone 1 or Zone 2 areas — such as workshops, warehouses, offices and filling stations in the petroleum, military-industry, chemical, machinery, pharmaceutical and metallurgical sectors.
Need a quotation for the FB series?
Tell us the zone, the gas group and the impeller diameter you need, and our engineers will confirm the model (FB-400 to FB-750) and prepare the quotation.
Technical data is reproduced from the manufacturer’s sheet for the FB series. The sheet does not state the gas group beyond the d IIB T4 marking shown; for Group IIC atmospheres or dust hazards, send us the area classification and our engineers will confirm suitability before you order. Dimensions are in millimetres unless stated otherwise.
