Negative pressure fans, as one of the many ventilation and cooling devices in the market, have now gained the favor of many consumers. So what makes negative air compressors stand out among many devices? Next, the editor will introduce the advantages of negative air compressors to everyone and take them to a deeper understanding.
Negative pressure fan is a cooling principle that utilizes air convection and negative pressure ventilation. It is a machine that naturally sucks in fresh air from the opposite direction of the installation site – the door or window – to quickly force the indoor hot gas out of the room. Any poor ventilation problem can be improved, and the cooling and ventilation effect can reach 90% -97%.
1. Ventilation and cooling, with good smoke and dust removal effects. The negative pressure fan utilizes the physical principle of negative pressure ventilation and air convection. The operation of the fan is to forcibly extract harmful indoor air such as high temperature, stuffiness, smoke, odor, and dust from the outside, while introducing fresh outdoor air into the room, creating a cool and fresh environment. It is best to cooperate with the negative pressure fan and water curtain, making the indoor environment more cool and generally reaching a beautiful environment of 26 degrees Celsius.
2. The scope of application is very wide, and various places with dense crowds, high heat sources, or prone to pollution, high temperatures, stuffiness, smoke, odors, dust, and other poorly ventilated areas can all exert significant effects. For example, textile workshops, clothing workshops, injection molding workshops, hardware factories, shoe material factories, electronic factories, etc., corresponding systems can be designed according to their different environments, and different wind speeds and volumes can be adjusted according to the specific indoor conditions, which is very flexible.
3. Negative pressure fan is the product that causes the least damage to the customer’s installation environment in ventilation and cooling equipment products. It does not occupy the customer’s space and does not require the installation of air ducts. It is usually installed in windows, walls, or roofs.
The main characteristics of fiberglass negative pressure fan: The blades of the fiberglass negative pressure fan are made of aluminum die-casting material, which is sturdy, durable, and has a large air volume. Balance testing to ensure smooth product operation and increase the service life of the entire machine.
1. Good electrical performance
The SMC materials used in the manufacturing of electrical products have the following electrical properties: insulation protection, and electrical indicators meet the standards. This material not only has electrical insulation, but also maintains good dielectric properties at high frequencies, is not affected by electromagnetic effects, and does not reflect electromagnetic waves.
2. Chemical corrosion resistance
Fiber reinforced polyester materials have excellent corrosion resistance to acids, dilute alkalis, salts, organic solvents, seawater, and other corrosive properties, while metal materials are not resistant to acid or seawater corrosion.
3. Lightweight and high
Specific strength and specific modulus are one of the indicators to measure the load-bearing capacity of materials, and the specific modulus of fiberglass negative pressure fans is equivalent to that of steel.
4. Good fatigue resistance
The tensile strength of SMC materials is slightly better than that of steel, and the fatigue limit of steel and most metal materials is 40% -50% of their tensile strength, while the fatigue limit of SMC materials is generally higher than this value, up to 70% -80%.
5. Weak sensitivity to gaps
When the component is overloaded and a small amount of fibers break, the load is quickly distributed on the undamaged fibers to regain mechanical equilibrium. This is incomparable to metal components.
6. Low thermal conductivity and low expansion coefficient
The thermal stress generated when there is a temperature difference is much smaller than that of metals.
7. Long service life
The usage history in Europe can prove that the service life is at least 20 years or more; After simulated aging tests, it has been shown that its service life is over 20 years, far exceeding that of traditional materials such as metals.
8. Flame retardant and smokeless
Flame retardant SMC materials can achieve FVO (advanced non-metallic materials) flame retardancy registration.
