1、 Overview of SLF Jet Fan
Jet fans are mainly used in longitudinal ventilation systems of highway and railway tunnels. The fans are generally suspended at the top or on both sides of the tunnel and do not occupy traffic area. No need to build additional air ducts, low construction cost, and it is a very economical ventilation method.
When the fan is working, it can generate high thrust from the given energy. At this point, a portion of the total air flow passing through the tunnel is sucked in by the fan, and after the impeller performs work, it is ejected at high speed from the outlet. be based on; The principle of mid-range transmission is that high-speed airflow will transfer energy to the air inside the tunnel, pushing the air inside the tunnel to flow forward together. When the flow velocity decays to a certain value, the next set of fans continues to operate. In this way, fresh air is drawn in from the entrance of the tunnel and polluted air is discharged from the exit.
The SLF jet fan has the following characteristics:
1. Wide performance range, with greater choice.
2. Low energy consumption and high thrust.
3. The specially designed muffler effectively controls the noise of the fan.
4. A precisely balanced impeller ensures smooth operation of the fan.
5. A dedicated electric motor enables the fan to operate reliably for a long time, with a running time exceeding 20000 hours.
6. T-shaped bidirectional ventilation equipment, with equal forward and reverse wind speeds, can achieve reverse air supply by simply changing the motor direction.
7. Equipped with a dual speed motor, low-speed operation can reduce operating costs when there is strong natural ventilation.
8. Easy to maintain.
9. The appearance of the fan is beautiful and generous.
2、 Model Description of SLF Jet Fan
For example:
SLF-90K-4P-D4 refers to an SLF jet fan with an impeller diameter of 90cm, equipped with a 4-pole motor, a fourth type of blade installation angle, and unidirectional ventilation.
