High Efficiency Industrial Axial Flow Fan Series - China Suppliers and Factory for Reliable Solutions
Product Overview
The main features of the DZ type axial flow fan are wide blades with large chord length, spatial distortion, and inclined blade shape. It can achieve the required air volume and pressure at low speeds, reducing the noise of the fan.
According to diameter, it is divided into 9 specifications ranging from 250 to 1000 mm. Each specification has 4 blades.
Product Classification
By Structural Shape
Available in multiple structural configurations to meet installation requirements:
Noise Optimization: To meet the noise requirements of different places, the fan can be equipped with different lengths of mufflers.
By Usage Environment
- General Type: Suitable for non-flammable, non-explosive, and non-corrosive gas environments.
- Anti-corrosion Type: The impeller and casing are made of fiberglass reinforced plastic (FRP), suitable for environments containing corrosive gases.
- Explosion-proof Type: The motor is of flameproof type and the blades are made of aluminum alloy, suitable for environments with flammable and explosive gases, with an explosion-proof grade of EXdIIBT4.
Product Application
Fans can be widely applied in industrial and mining enterprises, as well as in wall-type exhaust systems, position supply air systems, duct ventilation, and roof ventilation in civil buildings.
They are used in ventilation and air conditioning systems of various industrial and mining enterprises, such as those in:
Frequently Asked Questions
1. What are the key design features of DZ type axial flow fans?
The DZ type fan is engineered with wide blades, a large chord length, spatial distortion, and an inclined blade shape. This aerodynamic design enables the fan to achieve required air volume and pressure at low rotational speeds, significantly lowering operating noise.
2. What sizes and performance ranges are available for this fan series?
The fan series covers 9 diameter specifications ranging from 250 mm to 1000 mm. Each unit features a 4-blade assembly, offering an air volume range of 1,000 to 48,000 m³/h and an air pressure range of 40 to 400 Pa.
3. What mounting and structural types are offered?
DZ axial fans are categorized into three main structural types: wall type, post type, and pipeline type, allowing flexible installation for diverse duct and wall ventilation setups.
4. Which models should be selected for corrosive or explosive environments?
For corrosive gases, the Anti-corrosion Type with fiberglass reinforced plastic (FRP) impellers and casing is recommended. For hazardous environments with flammable or explosive gases, the Explosion-proof Type with flameproof motor and aluminum alloy blades (EXdIIBT4 grade) is required.
5. Can the noise level of the DZ fan be further minimized?
Yes, in addition to its low-speed aerodynamic blade design, the fan can be equipped with mufflers of various lengths to satisfy specific acoustic and low-noise requirements.
6. What industries commonly utilize DZ axial flow fans?
DZ fans are widely implemented in chemical, light industry, food, pharmaceutical, and metallurgical facilities, as well as wall exhaust, duct ventilation, and roof ventilation systems across various civil buildings.
