    Negative pressure fan is a popular model in the ventilator industry. Generally there are galvanized sheet negative pressure fan and FRP negative pressure fan. There are some differences between the two types of fans. Xiaobian has many years of practical field application experience in the fan industry and recommends FRP negative pressure fans . Why is this recommended in particular? Because FRP negative pressure fans have their own unique advantages, today I will introduce the difference between galvanized sheet negative pressure fans and FRP negative pressure fans.

    First, let ’s review the principle of negative pressure fans. The working principle of negative pressure fans is mainly the cooling principle of air convection and negative pressure ventilation. It is a natural intake of fresh air from the opposite door or window of the installation site Air, forcing the sweltering air from the room to be forced out of the room quickly, any machine with poor ventilation can be improved.

    The difference between galvanized negative pressure fan and FRP negative pressure fan is reflected in the following five aspects.
    1. Different materials: Negative pressure fans are made of galvanized sheet and glass steel according to the material of the outer frame.

    2. Different transmission methods: Both have the function of ventilation and cooling, but they are different.

    Galvanized sheet negative pressure fan: The motor uses belt drive blades, and the belt is subject to corrosion and wear and requires regular maintenance;
    Glass fiber reinforced plastic negative pressure fan: the direct drive fan is used to prevent the belt from being corroded and worn, and it is truly maintenance-free;
    3. Galvanized sheet negative pressure fan in terms of service life: Galvanized sheet material, not resistant to acid and alkali, non-corrosive, and short service life;
    FRP negative pressure fan: FRP material, resistant to acid and alkali corrosion, long service life.
    4. In terms of noise:
    Galvanized plate negative pressure fan: The shell is made of galvanized material, which is easy to generate metal resonance and has a relatively large noise;
    Glass fiber reinforced plastic negative pressure fan: The shell is made of SMC material and has low noise.
    5. In terms of fan blades:
    Galvanized sheet negative pressure fan: the fan blades are stamped and formed at one time, fastened with forged gas screws, and calibrated by computer precision balance;
    Glass fiber reinforced plastic negative pressure fan: The blade is an improved 6-blade fan blade, which has the largest air volume in the same type and fan of the same specification and the lowest operating cost.
    In general, based on the above five points, FRP negative pressure fan is better than galvanized sheet negative pressure fan. If the capital cost allows, it is recommended to buy a FRP negative pressure fan as a ventilation cooling device, which is more durable and easier to clean, and the use effect will be doubled, and the cost of the FRP negative pressure fan is not much higher than the galvanized sheet. The overall price is between 1000-2500, and specific non-international prices need to be explained separately.

    Of course, the installation of negative pressure fans must also take into account the on-site engineering aspects, so if it is a new factory building or a retrofitted factory, it is recommended that you can also find a professional fan manufacturer to inspect the site. If it is in the Shanghai area, we can come to the door for free Look at the scene and give you reasonable suggestions and specific implementation plans for budget evaluation. I believe it can still help you, thank you!
