Product Description

Roof axial fans typically consist of components such as impellers, housings, motors, bases, wind caps, diffusers, and louvers. The impeller is the core component responsible for air movement; the housing supports and protects internal parts; the motor provides power for the impeller's rotation; the base secures the fan; and the wind cap, diffuser, and louvers optimize airflow and prevent rain and wind intrusion. By driving the impeller with the motor, the blades on the impeller push the air, causing it to flow along the axis of the fan, creating axial airflow, thus facilitating indoor and outdoor air exchange for ventilation purposes.

Characteristics of roof axial fans

1. High ventilation efficiency: Capable of generating significant airflow, quickly and effectively promoting air circulation between indoors and outdoors, meeting building ventilation needs.

2. Low noise levels: Through optimized blade design and motor selection, the noise generated by roof axial fans during operation is relatively low, minimizing interference with the surrounding environment.

3. Good corrosion resistance: Some roof axial fans have impellers and housings made from corrosion-resistant materials such as fiberglass or aluminum, capable of withstanding harsh weather conditions and chemical substances, suitable for various environments.

4. Aesthetic appearance: With simple and smooth designs, the wind cap, diffuser, and other components are aesthetically pleasing, coordinating well with building exteriors and maintaining overall visual appeal.

5. Easy installation: Featuring a relatively simple structure and lightweight, the installation process is straightforward, allowing direct installation over roof openings or via brackets.

Types of roof axial fans

1. DWT-I type: Large airflow, low noise, high efficiency, light weight, stable operation, and aesthetic appearance. Can be manufactured in corrosion-resistant and explosion-proof versions, suitable for power plants, chemical industries, rubber, pharmaceuticals, food processing, metallurgy, warehouses, and high-end civil buildings for supply and exhaust ventilation. Sizes range from 3# to 24#, with airflow rates from 1450 to 220800 m³/h and total pressure from 62 to 330 Pa.

2. ZTF-W series: All models have noise levels limited to 60 (A) decibels or less, featuring high efficiency, corrosion resistance, light weight, and reliable operation. Widely used in various substations, factories, buildings, and industrial structures for localized and comprehensive exhaust ventilation, especially suitable for hotels, schools, hospitals, theaters, or areas near residential zones requiring low noise.

3. RAF type: Utilizes conical hubs and twisted wing-shaped blades, suitable for medium-low pressure and high-flow ventilation scenarios. Features large airflow, high pressure, energy-saving, lightweight, and compact structure. Can be produced in corrosion-resistant and explosion-proof versions, widely used in mechanical, chemical, rubber, pharmaceutical, textile, and other industries' workshops and high-end civil buildings for rooftop ventilation.

Application scenarios

1. Industrial buildings: such as factory workshops, warehouses, etc., used to expel waste gases, hot air, dust, etc., generated during production, introduce fresh air, improve working environment, ensure workers' health and safety, and also help with normal equipment operation and product quality control.

2. Commercial buildings: like shopping malls, supermarkets, hotels, office buildings, etc., can be used for ventilation systems to provide comfortable indoor air environments, meet people's breathing needs, enhance indoor air quality, and can also be used for auxiliary ventilation in air conditioning systems to improve the efficiency of air conditioning systems.

3. Civil buildings: such as residential homes, apartments, etc., can be installed on rooftops for ventilation and air exchange, expelling indoor fumes, moisture, odors, etc., keeping indoor air fresh, and improving living conditions.

Other places: such as sports stadiums, exhibition halls, airport terminals, train stations, etc., large public buildings, as well as sewage treatment plants, garbage treatment plants, etc., environmental protection facilities, also require roof axial flow fans to achieve ventilation and air exchange, deodorization functions.

Selection points

Air volume and air pressure: Based on the size of the space and ventilation requirements of the usage site, calculate the required air volume and air pressure, and select an appropriate fan model to ensure that the fan meets the ventilation and air exchange requirements.

Usage environment: Consider the environmental conditions of the usage site, such as temperature, humidity, corrosive gases, etc., and choose fans with corresponding protection levels and corrosion resistance performance, such as explosion-proof roof axial flow fans in places with flammable and explosive gases.

Noise requirements: If the usage site has high noise requirements, such as hospitals, schools, residential areas, etc., low-noise fans should be selected, and soundproofing equipment can be considered to reduce the noise produced by fan operation.

Motor power: Based on parameters such as fan air volume, air pressure, and rotational speed, select a suitable power motor to ensure that the motor provides sufficient power to the fan, while also considering the energy-saving performance of the motor to reduce operating costs.
