Product Description


LKZD series forward-curved blade single-inlet shaft-driven centrifugal fan is a special fan for air conditioning system developed by our company. It is characterized by that the motor is located at the non air inlet side of the fan, the motor shaft is directly connected with the fan impeller, the motor does not contact with the conveying medium, the structure is simple and reliable, especially suitable for conveying clean gas, dangerous gas or other special gas.

The fluid model of this series of fans has been optimized by CFD advanced technology, which not only increases the output pressure, but also reduces the noise and improves the efficiency. It has the characteristics of energy saving and low noise. It is especially suitable for supporting various air conditioning, refrigeration, purification, fresh air units and other products, and has been widely used in schools, hospitals, factories, mines, cold chain and other fields.

The fan of this series has different directions of 0 °, 90 °, 180 ° and the motor can be vertically and horizontally installed. It can also be customized to other directions according to the needs of users. The installation form is flexible and convenient.

LKZD series of fans has the following remarkable advantages:

1. The motor is not in contact with the conveying medium, and only the air inlet, impeller and volute are used as the overcurrent components, which are easy to meet the special requirements of cleaning, anti-corrosion, explosion-proof, etc;

2. The forward multi wing impeller with high pressure, low noise, high efficiency and low noise is adopted;

3. The direction of the air outlet and the installation position of the motor can be specially customized, and the installation form is flexible and convenient;

4. Our self-developed matching motors have better reliability and service life than ordinary motors after with optimization of power;

5. Our fans can have different power supplies, such as single-phase, three-phase, DC power supply and others. Voltage and frequency can be as the needs of users from different countries;

6. Our fans can have different speed modes, such as single-speed, double-speed, three-speed and stepless speed regulation to meet the needs of users for air volume regulation.

Installation Method

1) The rotating direction of centrifugal fan is divided into CW and CCW according to the rotating direction of impeller. To LKZD Centrifugal Fans: facing the motor, the clockwise direction of impeller rotation is called CW, and the counter-clockwise direction of impeller rotation is called CCW.

2) Air outlet angle: the angle between the air outlet and the installation surface.

Vertically installed motor of LKZD series has no motor mounting base, therefore, it only has the characteristics of rotation direction and no outlet angle;

Horizontally installed motor of LKZD series has three main types according to the outlet angle: 0 °, 90 °, 180 °. It can also be customized to other directions according to the needs of users.

Technical Parameter & Drawing

Work Environment

1) Altitude not more than 1000 meters;

2) The ambient temperature is not lower than - 25 , not higher than 40 ;

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

4) The conveying gas does not contain acid, alkaline and corrosive medium, and the dust content is not more than 150mg / m3.

When the working environment does not meet the above requirements, it needs to be explained when ordering. We can customize the product according to the specific site conditions.

Performance Range

Flow: 4009900 m3/h

Total pressure: 1501000 pa

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

Matters Needing Attention

1. Before use, please check carefully:

(1) Whether the motor lead wires are intact;

(2) Whether the connecting bolts are loose;

(3) Whether there is serious deformation of fan volute, impeller, fan shaft and other components;

(4) Rotate the fan impeller by hand, the hand induction rotation is stable, without obvious stuck phenomenon.

2. Installation

(1) The fan chassis must be installed horizontally, and it is strictly prohibited to install vertically or obliquely;

(2) The grounding bolt of the fan shall be connected reliably;

(3) The fan shall be equipped with phase loss and overload protection devices;

(4) Be careful when installing. Do not put your hand into the pulley to avoid crushing.

3. Start up and Operation

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

(2) The rotation direction of the fan impeller shall be the same as that of the turning mark;

(3) The operating current of the fan shall not exceed the defined current, otherwise the motor will be damaged or burnt;

(4) When the fan is running, it is strictly prohibited to extend the body or foreign matters to the inside of the fan, and it is strictly prohibited to approach the belt and pulley to avoid danger.
