ASTEXT Specification	Roof Fan FDvF 200/225 for conveyance of aggressive, optionally explosive air, vapours and mist with a content of dust less than 5 mg/m³ and a temperature of -5 to +40°C. Maximal allowable environmental temperature of +40°C. Housing made from PPs injection moulded with flow optimised guide vane, with an integrated maintenance-free seal-system, consisting of a condensate runoff as a circular drip edge and a labyrinth seal, for ex-version additionally with externally refillable grease-barrier and lip-seal. Pressure-side with special formed and elastic blow out/ bird protection grid (IP20). Condensate runoff support at the lowest point of the housing. Impeller made from PPs injection moulded with rear blade rows for a guaranteed negative pressure on the axle lead-through in service. Direct drive by an IEC-34 three-phase motor, technically gas-proof to the medium, with heat resistant connection parts on the housing and impeller to avoid deformation due to a technical breakdown. Guided engine cooling air through separate inlet and outlet ducts, in order to avoid uncontrolled circulation of the cooling air.
