Product Description

LKZWH SERIES BACK-CURVED BLADE SINGLE-INLET SHAFT-DRIVEN Centrifugal Fan WITHOUT VOLUTE

LKZWH series back-curved blade single-inlet shaft-driven centrifugal fan without volute is a new-typed fan developed by our company. It has no volute and can be directly installed in the equipment requiring ventilation or placed in any size of bellows. In this kind of special working situation, its efficient working area is wider than that of ordinary centrifugal fan, and its noise is lower. In addition, because the direction of its air flow is not limited by the volute, it can be used to replace large-diameter fans by simply installing several fans in the same air box to compose of a fan group, so as to reduce the noise and volume of the whole unit.

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, HVAC, refrigeration unit and other products, and has been widely used in schools, hospitals, factories, mines, cold chain and other fields.

The fan of this series can be vertically or horizontally insalled.

LKZWH series of fans has the following remarkable advantages:

1. Wider and more efficient working area, more free air direction;

2. The utility model has the advantages of simple structure, small volume, light weight and flexible and simple installation mode;

3. 3. The backward impeller with optimized design has high efficiency, low noise, energy saving and environmental protection.
