Closed Impeller

Product Features

The Closed Impeller is a core component of industrial equipment and home appliances. Composed of a base, blades, and connecting parts, it is mainly made of aluminum alloy or engineering plastic.

It generates negative pressure suction through high-speed rotation (tens of thousands of revolutions per minute), easily drawing dust into dust collection devices.

Aluminum alloy version: Lightweight, corrosion-resistant, and supports angle adjustment;

Engineering plastic version: Lighter in weight but with slightly lower high-temperature resistance.Choose flexibly based on application scenarios.

Product Applications

With a wide range of applications, the Closed Impeller is suitable for both household and industrial fields:

Household use: Compatible with dust collection equipment, enabling efficient dust collection via high-speed rotational suction;

Industrial use: Adaptable to cooling tower fans, drying kilns, baking equipment, etc.It performs stably especially for cooling tower fans long exposed to high-temperature and high-humidity environments, and drying kilns requiring forward and reverse ventilation.

Core Advantages

Aluminum alloy Closed Impellers offer the following significant advantages:

High strength and low density: For example, the Hongjian HJ/18 blade model is made of precision die-cast aluminum alloy, maintaining high strength even with a blade diameter of 1800mm, while reducing motor load;

Excellent corrosion resistance: A dense oxide film forms on the aluminum surface, effectively blocking the corrosion of moisture and oxygen. LSF series products will not deform or corrode even after a month of operation during the rainy season;

Superior dynamic balance: Extremely low vibration and noise during high-speed rotation;

Flexible angle adjustment: Supports 15°-40° static stepless adjustment to adapt to various working conditions.
