PSO-JFA fans are JET FAN impulse devices that allow to solve ventilation problems in underground car parks with powered ventilation, removing most common pollutants, controlling smoke and heat in case of emergency and directing air and pollutants flows to the expected extraction points. PSO-JFA complies with Regulation (EU) No 305/2011. It is provided with CE marking, tested and certified according to EN 12101-3 Standard by a notified body. These PSHEVs are certified to operate in the event of an emergency (fire) with performance F200 (200°C / 120’), F300/120 (300°C / 120’) or F400 (400°C / 120’). They are also suitable to work in continuous at the maximum ambient temperature of 40°C. The main feature of PSO-JFA fan is the absence of ducts, which offers the following advantages: remarkable savings in installation time and costs; management costs reduction, with the possibility of ventilating or extracting in certain areas according to requirements; greater flexibility in case of system modifications. PSO-JFA axial fan is composed of: weather resistant steel sheet casing; high efficiency impeller made of die cast aluminium alloy, with airfoil blades; asynchronous three phase electric motor, IP 55 protection rating, directly coupled to the impeller; two cylindrical silencers made of galvanized steel sheet directly flanged to the fan; ceiling fixing system; inlet protection grid and outlet deflector (unidirectional version), or two deflectors (reversible version); wired service switch.
