JF Smoke Extraction Jet Fans
Available in Standard and ATEX Versions
Manufacturing Features:
Axial jet fan with galvanised steel casing.
The connection box is accessible by the side from a removable door.
Silencers are filled with mineral wool with high acoustic absorption properties, preventing most of the fan noise to be propagated.The silencer casing is made of galvanised steel.
Inner duct made of perforated galvanised steel sheet.
Standard asynchronous squirrel-cage motor with IP-55 protection and Class H insulation, Certified 400ºc/2h. Standard voltages 400V(Y) 50Hz for 1 speed motors and 400V 50Hz for 2 speed motors.
Highly Effective Silencers for Low Noise Operation
F400 jet fans feature highly effective silencers which are filled with mineral wool with high acoustic absorption properties, preventing most of the fan noise to be propagated.
JF F400: Long Range Jet Fan with 1 x Axial Fan and 2 x Silencers
• Large spaces where polluted air, or smoke from an accidental fire, needs to be removed effectively
• car parks
• Maximum working temperature: 60ºC
• ATEX rated versions
Unidirectional JF F400 UN is equipped with a protection guard at the inlet side and a deflector at the outlet. The deflector directs the air away from the ceiling and obstacles like beams or ducting, sweeping the whole volume of air to the closest extraction point.
Reversible JF F400 RE is equipped with protection guards on both sides.
