Detailed explanation of FRP fan performance:
Due to the continuous expansion of the market, the favor of customers and the continuous improvement of the fan impeller, the fiberglass negative pressure fan can be applied more and more widely. When installing the fiberglass negative pressure fan, it is usually installed outside the window of the workshop, and the lower air outlet is often selected to extract air from the outside, which can better extract the odor gas. It is widely used in chemical plants.
The use of fiberglass negative pressure fan with wet curtain can make the workshop cool down better. Even in hot summer, fiberglass negative pressure fan can also be used to cool down, so that you can have a better environment in the workshop, which is to enhance work efficiency.
FRP centrifugal fan is mainly composed of two parts: fan shell and impeller. The fan cover and impeller are made of anticorrosive fiberglass reinforced plastic fan made of anticorrosive material.
Function of FRP negative pressure fan
In the practical application of the fiberglass negative pressure fan, the fiberglass negative pressure fan is generally used for factory ventilation, especially in areas such as large smoke and dust, where the fiberglass negative pressure fan is installed on the wall at one side of the room, and the air inlet uses the window or door corresponding to the other side of the room, and the air conducts convection ventilation to the fiberglass negative pressure fan through the air inlet.
During this process, the doors and windows near the FRP negative pressure fan shall be kept closed, and the closed windows shall be closed as much as possible. The forced air is compensated to the room through the doors and windows on the air inlet side. Air is poured into the room from the air inlet. When a certain wind speed passes through, the fiberglass negative pressure fan is installed and discharged to the outside. The gas exchange rate of fiberglass negative pressure fan is 95. Through specific engineering design and design of ventilation speed and wind speed as required, the problems of high heat, harmful gas, dust discharge from the workshop and poor ventilation can be solved. The ventilation capacity can be achieved within a few seconds after the fan is turned on, which is the function of our fiberglass negative pressure fan.

Principle of FRP material
The concept of composite material means that one material cannot meet the use requirements, and needs to be composed of two or more materials to form another material that can meet people’s requirements, namely composite material. For example, although a single type of glass fiber has high strength, it is loose between the fibers, can only bear tension, can not bear bending, shear and compressive stress, and is not easy to make a fixed geometric shape. It is loose soft. If they are bonded together with synthetic resin, they can be made into various hard products with fixed shapes, which can bear both tensile stress and bending, compression and shear stress. This constitutes a glass fiber reinforced plastic matrix composite. Because its strength is equivalent to that of steel, it also contains glass components, and it also has the color, shape, corrosion resistance, electrical insulation, heat insulation and other properties of glass. Like glass, it has formed this easy-to-understand name “fiberglass” in history.
Products Description
According to the material classification of glass fiber reinforced plastics, it should belong to the series of composite materials, because in the production process of glass fiber reinforced plastics, glass fiber is mainly used, and some reinforcing materials are combined, so it is called glass fiber reinforced plastics, which can also be called fiber reinforced plastics. The products included in the reinforcement materials include: felt, yarn, tape, glass cloth and other materials.
First of all, its strength is very high, and its density should be controlled between 1.5 and 2.0. In addition, its thermal performance is relatively good, so it is no problem to apply in the environment with high temperature. In addition, it has the advantages of corrosion resistance and good designable process.
Principle of negative pressure fan
The air discharged from the fiberglass negative pressure fan and environmental protection air conditioner will reduce the indoor air pressure, and the indoor air will become thinner, forming a negative pressure zone, and the air will flow into the room due to the pressure difference compensation. In the practical application of industrial plant, the FRP negative pressure fan is installed on one side of the plant, the air inlet is located on the other side of the plant, and the air flows from the air inlet to the FRP negative pressure fan to form a convection blow. During this process, the doors and windows close to the FRP negative pressure fan are kept closed, and forced air is forced to flow into the workshop through the door and window compensation at the air inlet. The air flows into the workshop from the air inlet, flows through the workshop, and is discharged from the workshop by the fiberglass negative pressure fan. The ventilation is complete and efficient, and the ventilation rate can reach 99%. Through specific engineering design and air change speed and wind speed designed according to the needs, any high heat, harmful gas, dust and smoke can be quickly discharged from the workshop, and any poor ventilation problem can be completely solved at one time. The ventilation effect can be achieved within a few seconds from opening the fan.

Inspection items before installation of fiberglass negative pressure fan
1. Check whether the fiberglass negative pressure fan is damaged during transportation.
2. Check whether all parts are loose during installation. If you are not sure, you can tighten them again
3. When powering on, professional electricians should be invited to distribute power. The control switch should have phase loss protection, leakage protection, current overload protection, etc. The wires and cables used should be able to bear the load of motor current. The joints of wires should be insulated with electrical tape. All lines should be buried in the trunking and conduit according to the requirements of the specification.
4. After the installation of the fiberglass negative pressure fan, it is necessary to clear all obstacles around before use.
