What is an ec motor duct fan?
ec motor duct fan
Ec motor duct fan is a direct current, external rotor type of motor in which AC voltage is converted into direct voltage by a commutator. Without getting too technical, it is a brushless motor that runs on DC voltage using an AC power supply to combine the best of both technologies.

Which motor fan is the best, cheapest to buy today?
Motor fan is actually a ventilation fan, with the suction and blowing directions parallel to the fan axis. Currently on the market motor fans are divided into two basic types:
Direct Motor Fan: A fan with blades directly attached to the motor.
Indirect Motor Fan: Uses a belt to transmit rotational force from the motor to the blade.
Besides, people also rely on these two main types to create different fans such as:
Pressure generating fans
non-pressure generating ec motor duct fan
Motor fans with round body
 fixed and non-fixed square body
The most common non-pressurized motor fans are square body motor ventilation fans, also known as industrial exhaust fans or industrial fans.
How does the motor fan work?
People often install motor fans in factories to serve the needs of heat loading, ventilation, and cooling of the factory and at the same time transporting toxic air to bring a fresh environment to the entire space. The fan also helps to dispel the heat comes by the heat dissipation of the machines.
The wind obtained from the motor ventilation ec motor duct fan will soothe the uncomfortable, hot stuffiness of the factory, helping the workers to feel comfortable and more during work. In greenhouses, classrooms, offices, motor fans will help ventilate, creating a feeling of coolness, ventilation and comfort.

Working principle of motor fan
Ventilation system to cool the factory by industrial exhaust fan is designed according to the principle: One end of the workshop installs a motor exhaust fan system to suck out toxic gases, heat and moisture inside the factory. The other end of the workshop leads air from outside through the louver system.
ec motor duct fan only have a small number of blades and cut the air directly, so if the air environment has dirt, it will cause rapid corrosion of the blades due to friction with dust and air. The motor placed outside moves by the belt, when the contact between the belt and the pulley has dust with a large size, it will damage the belt.
Advantages of ec motor duct fan
Quiet operation without noise:
Besides factories and enterprises, motor fans are also common by many office families. That is why the requirements for low noise are very popular among manufacturers. Most of the motor fan models on the market have a smart design that minimizes the noise level to keep the space in use quiet and unaffected.
Consume less energy:
Saving energy is the top concern of users, so motor exhaust fans are also popular on this factor.
Stable operation, high durability:
The feature of this type of ec motor duct fan is that it is often installed on high and is difficult to repair. However, you can rest assured that they have been thoroughly researched to ensure quality and durability. Along with that, the warranty mode of the motor fans is quite long which a plus is also so that users can feel more secure when buying them.

Are you looking for a specialized device to absorb odors and hot air for home kitchens and restaurant kitchens? The axial exhaust fan will be the most suitable device with the most effective and thorough exhaust function.
Product description axial exhaust fan
Axial exhaust fan, also known as coaxial exhaust fan, is suitable for exhaust systems, ventilation in kitchens, warehouses, restaurants, drying workshops. Moreover, a special design that does not catch fire, Explosion and corrosion resistant. Ec motor duct fan can be common in places with gas production, hot air and places with little air.
Depending on which direction Ec motor duct fan directs the air flow, we choose these fans:
1.Supply air - forcing fresh air into the room;
2.Exhaust - common to remove harmful gases and exhaust air from the premises.
Most often, both types of fans come in a single system in pairs. And it is not always possible to simply turn one fan in one direction. The dimensions of the exhaust and supply air ducts are different. Moreover, they are the characteristics of the two streams. 
This is a fan line with a structure for the air to draw in and blow out parallel to the ec motor duct fan shaft. This flow of air is wind for short. Understandably, a coaxial fan is a fan with the direction of air intake. It blows air parallel to the axis of the fan.
