The ZL series axial flow fan is a specialized fan developed by our company for air conditioning systems, suitable for ventilation situations with high flow rates and low air pressure. Its fluid model has been optimized by advanced CFD technology, which not only increases output pressure but also reduces noise and improves efficiency. It has the characteristics of energy saving and low noise, and is particularly suitable for supporting various air conditioning, purification, fresh air, HVAC, refrigeration units. It has been widely used in hotels, restaurants, office buildings, residential areas, schools, hospitals, factories, mines, theaters, car air conditioning and other fields.

This series of fans comes in two different forms of supporting motors: single-phase motors and three-phase motors. Special supporting motors with different voltages and frequencies can also be customized according to your user needs, making it convenient for applications in different countries, regions, and fields.

This series of fans has the following significant advantages:

1. Adopting optimized impeller design, with high air volume, low noise, high efficiency and low noise, environmentally friendly and energy-saving;

2. Simple and lightweight structure, easy installation method;

3. The independently developed supporting motor has been carefully optimized for power, and its reliability and service life are superior to ordinary motors.

Typical model: ZL 400 B – 4 C

Model meaning:

ZL： Axial flow fan

400: nominal diameter of impeller (mm)

B： The direction of the air outlet is B when blowing from the motor towards the blades, and there is no such code when blowing from the blades towards the motor

4: Number of supporting motor poles, where EC represents brushless DC motor

C： Motor power supply, single-phase power supply is C, three-phase power supply does not have this code

The working environment suitable for this series of fans is:

1) Altitude not exceeding 1000 meters;

2) The ambient temperature shall not be lower than -25 ℃ and not higher than 40 ℃;

3) The relative humidity of the environment shall not exceed 90%;

4) The transported gas does not contain acidic, alkaline, or corrosive media, and the dust content is not greater than 150mg/m³.

When the working environment does not meet the above requirements, it needs to be explained when placing an order. Our company can customize according to specific on-site conditions.

Flow rate: 3200-9000m³/h

Full pressure: 100-180Pa

Beyond this range, please choose other series of fan products from our company, or contact our company for customization.

1. Pre use inspection

Before use, please carefully check:

(1) Whether the motor leads are intact and undamaged;

(2) Are all bolts loose;

(3) Are there severe deformations in components such as the diffuser, blades, motor shaft, and bracket;

(4) Rotate the impeller by hand, and the rotation is smooth and there is no obvious lag phenomenon.

2. Installation

(1) The grounding bolt of the fan should be reliably grounded;

(2) The fan should be equipped with phase loss and overload protection devices;

3. Start and Run

(1) Before starting the fan, the working power supply should be checked and must be within the range of rated voltage ± 5% and rated frequency ± 1%;

(2) The rotation direction of the fan impeller should be the same as the direction marked;

(3) The operating current of the fan should not exceed the nameplate current, otherwise it may cause damage or burning of the motor;

(4) During the operation of the fan, it is strictly prohibited to extend one's body or foreign objects towards the inside of the fan to avoid danger.
