Application scenarios:

Pipeline fans are mainly used for ventilation inside pipelines, such as underground garages, basements, etc., with the aim of expelling polluted air and odors, reducing the load on ventilation pipelines, reducing airflow resistance, and improving ventilation efficiency.

The exhaust fan is installed near indoor ventilation holes, such as in bathrooms, kitchens, bathrooms, etc., to expel damp and dirty gases and odors, and purify indoor air.

Type of rotor:

The rotor of the pipeline fan is directly driven and installed inside the pipeline. The power of the motor is transmitted to the fan blades through a transmission device, which rotates the fan blades to achieve ventilation.

The rotor of the exhaust fan is usually belt driven, installed outside the equipment, and transmits the power of the motor to the fan blades through the transmission belt, which also rotates the fan blades and expels indoor polluted air.

Working principle:

The working principle of a regular exhaust fan is to extract dirty air from indoors and exhaust it outdoors through pipelines to achieve indoor air circulation and exchange.

The ducted exhaust fan sucks in air, compresses it, and then exhausts it, serving as a guide for ventilation.

Installation method:

The installation of a regular exhaust fan is relatively simple and can be directly fixed at a high place.

Pipeline exhaust fans require pipeline layout and laying, and installation is more complex, usually requiring a professional construction team to operate.

Noise level:

The volume of a regular exhaust fan is relatively low, usually around 30-40 decibels.

Pipeline exhaust fans generate significant noise during use, as they require high-speed rotating motors to compress the air and emit noticeable noise.

Maintenance requirements:

The service life of a regular exhaust fan is generally 5-7 years, and daily dust removal and cleaning are sufficient.

The service life of pipeline exhaust fans is relatively long, but due to their particularity, they need to be cleaned regularly
