Axial Jet Fan-With Silence

FJF series axial fans are used in indoor parking lots, tunnels, etc. It was developed for ventilation purposes in places without using air ducts. Jet Fans, produced in five series: FJF315, FJF 400, FJF 450, FJF 560, FJF 630, provide air flow rates between 4,750 m³/h – 36,000 m³/h. Highly efficient, aluminum cast and angle-adjustable blades are used for our jet fans. “Single-Way” or “Bi-Way” types are available. FJF series axial jet fans are designed to exhaust hot smoke without interruption while operating in fire situations. CE and EN certified engines with fire resistance classes F200/2h, F300/2h, F400/2h are used.

Ductless car park ventilation systems are impulse and induction jet-fan smoke extraction systems. The difference between impulse and induction jet fans is that in the induction jet fan, the high air speed can also affect the air around it and drag it together. Since both system fans are short in height, they can be mounted on the ceiling on driveways in garages without any problems. In addition, since the air outlets of induction fans are narrow, the air flow is limited to every beam etc. can overcome such obstacles. The cost of these systems is lower than the ducted system. These systems have a low noise level for daily air needs. Moreover, especially with the advantage of inductivity, the garage can be ventilated without dead spots. These systems are complicated, with rotating beams etc. Since there is no duct connection, their installation is easy. The energy consumption of these systems is less than other systems. From a static perspective, there is no need for duct wall holes, especially on the lowest floors. It is used for “Daily Co ventilation” of all kinds of large indoor car parks and for “Smoke Exhaust” in case of a possible fire.

 Jet fans provide air flow in the desired area/zone. Therefore, the duct, culvert and damper on the duct etc. used in the duct system. equipment is eliminated and initial investment costs are very low compared to other systems.

– While only smoke evacuation is possible with the ducted system, smoke control is possible in jet fan systems and the distribution of air velocities within the parking lot is better. In this way, escape routes will be cleared of smoke, damage to the parking lot will be minimized, and most importantly, the fire brigade will be able to easily detect the burning vehicle and intervene immediately.

– A better quality air mixture and homogeneous distribution is achieved with jet fan systems in daily ventilation.
