Negative pressure fans：
Negative pressure fans play a key ventilation and exhaust role in industry, manufacturing and some special environments, helping to maintain a safe, clean and comfortable working environment,
Negative pressure fans are usually composed of the following parts: air intake, air outlet, blade, motor and housing. The inlet and outlet are the two key parts of the negative pressure fan, which determine the ventilation efficiency and suction force of the negative pressure fan.
The wind blade is the core component of the negative pressure fan, and its shape and quantity directly determine the exhaust air volume and wind pressure of the fan. The motor is the power source that drives the wind blade to rotate, usually using a DC motor or an AC motor. The casing is the shell of the negative pressure fan, which is mainly used to protect the internal parts and reduce noise.
Suitable for high temperature or smelly workshop: such as heat treatment plant, casting factory, plastic factory, aluminum profile factory, shoe factory, leather factory, electroplating factory, various chemical plants. Suitable for labor-intensive enterprises: such as garment factories, various assembly workshops, Internet cafes. Horticultural greenhouse cooling ventilation, livestock pasture cooling. It is especially suitable for places that require cooling and humidity.
Applicable to the field of warehousing and logistics. Negative pressure fan can be installed alone, can also be used together with environmental protection air conditioning and industrial large fan, high temperature environment combination of environmental protection air conditioning, or industrial large fan will be better, cooling ventilation faster and more significant.
