Fiberglass negative pressure fan is a new type of ventilation equipment made of anti-corrosion fiberglass material, belonging to axial flow fan. Because the outer frame of the fan is made of anti-corrosion fiberglass material, the working principle is to use negative pressure ventilation to achieve air circulation, ventilation and cooling, so it is called fiberglass negative pressure fan. Fiberglass negative pressure fans have the characteristics of corrosion resistance, high air volume, low energy consumption, low speed, and low noise.
The difference between fiberglass negative pressure machine and ordinary negative pressure machine:
The fiberglass negative pressure fan is made of fiberglass shell, which is durable and corrosion-resistant; The ordinary negative pressure fan is made of galvanized sheet shell, which is prone to rust and corrosion. Fiberglass negative pressure fans can be used in corrosive environments; Ordinary galvanized sheet negative pressure fan cannot. The motor and impeller of the fiberglass negative pressure fan are directly integrated, and the motor drives the impeller to rotate; The motor and impeller of galvanized sheet are connected by a belt, so the maintenance rate is high. The blades of the fiberglass negative pressure fan are molded into shape; The blades of the negative pressure fan made of galvanized steel are stamped. In practical application, negative pressure fans are generally used for natural ventilation in industrial buildings of processing plants, and fiberglass negative pressure fans are chosen in some places with acid and alkali corrosiveness.
type
From the perspective of appearance and shape
1. The horn shaped fiberglass negative pressure fan has a horn shaped exhaust outlet, which is commonly referred to as a horn shaped fiberglass negative pressure fan by many people.
2. A square fiberglass negative pressure fan is called a square fiberglass negative pressure fan because the overall appearance of the fan is square
From the perspective of transmission mode
1. Belt type fiberglass negative pressure fan: The belt type speed is between 370-450 rpm, and it adopts a six pole or four pole aluminum shell motor with a protection level of IP55 F insulation. Products with low speed have relatively low noise.
2. Direct connection fiberglass negative pressure fan: There are three main types of direct motors: 12 pole 440 rpm, 10 pole 560 rpm, and 8 pole 720 rpm. 12 pole motors are the most commonly used, and fans with high speeds have high noise.
From the material of the fan blades
1. Aluminum alloy negative pressure fan: The fan blades are made of aluminum alloy material, with 3 and 6 blades.
2. Engineering plastic negative pressure fan: The fan blades are made of engineering plastic materials and have 6, 7, and 9 blades.
3. Fiberglass negative pressure fan: The blades are made of fiberglass material and have 3 and 6 blades.
application
In practical applications, fiberglass negative pressure fans are generally used for ventilation and air exchange in factory buildings, especially in places with acid and alkali corrosion. During installation, fiberglass negative pressure fans are installed on one side of the indoor wall window, and the air inlet is corresponding to the other side of the indoor window or door. The air is drawn and exchanged through the air inlet to the fiberglass negative pressure fan through convection. During this process, the doors and windows near the fiberglass negative pressure fan remain closed, forcing air to flow into the room through the compensating doors and windows on one side of the air inlet. The air then flows into the room through the air inlet, passing through at a certain speed, and is discharged outdoors from the location where the fiberglass negative pressure fan is installed. The fiberglass negative pressure fan provides thorough and efficient ventilation, with a ventilation rate of up to 99%. Through specific engineering design, designing air exchange rates and wind speeds as needed, any high heat, harmful gases, dust and smoke can be quickly discharged from the workshop, and any ventilation problems can be completely solved in one go. Ventilation can be achieved within a few seconds of turning on the fan.
Suitable for workshops with high temperatures or odors, such as heat treatment plants, casting factories, plastic factories, aluminum profile factories, shoe factories, leather goods factories, electroplating factories, and various chemical factories. Suitable for labor-intensive enterprises, such as clothing factories, various assembly workshops, and internet cafes. Ventilation and cooling of horticultural greenhouses and livestock farms. Especially suitable for places that require cooling and a certain level of humidity. Various textile factories, such as cotton mills, woolen mills, linen mills, weaving mills, chemical fiber mills, warp knitting factories, elastic adding factories, knitting factories, silk weaving factories, sock factories, etc. Applicable to the neighborhood of warehousing and logistics.
