PPH Centrifugal Fan

The PPH centrifugal fan of Xinda Chemical from China is specially designed for harsh corrosive gas environments. The core components of the fan, such as the impeller and casing, are all made of high-crystalline polypropylene homopolymer (PPH) through high-pressure injection molding and hot air welding processes. This material can withstand the erosion of the vast majority of acids, alkalis and organic corrosive gases for a long time. The ventilation and air exchange efficiency can reach over 98%, and there is no risk of metal ion pollution.

It is especially suitable for high-demand places such as electronic clean workshops, pharmaceuticals and food.Compared with the traditional metal fan, its weight is only about one-third of the steel fan, the installation and handling is extremely convenient, and the rust problem is fundamentally eliminated, and the maintenance cost is significantly reduced.The equipment runs smoothly, the noise is low, conforms to the national ventilator standard, widely used in the chemical industry, electronics, metallurgy, laboratory and other industries of ventilation and exhaust gas exclusion.

Working principle

Our PPH centrifugal fan operates based on the principle of converting kinetic energy into potential energy: the high-speed rotating impeller accelerates the gas, and through the process of changing the flow direction and deceleration, kinetic energy is converted into pressure energy. In a single-stage fan, the gas enters the impeller axially and then turns radially. After further deceleration and pressurization through the diffuser, the pressure is mainly generated within the impeller, with the diffuser process serving as a secondary factor. The multi-stage fan guides the airflow into the next-stage impeller through the return vane to achieve higher pressure.

Structural composition

Its structure consists of a casing (made of PPH material), a main shaft, an impeller, a bearing transmission mechanism and a motor. The casing is divided into integral type and semi-open type. The semi-open design is convenient for maintenance.

Main Features

Core performance advantages

Strong corrosion resistance: Our PPH centrifugal fan adopts PPH (polypropylene) material, can effectively resist chemical corrosion, suitable for chemical, pharmaceutical and other corrosive environment.Low-noise operation: The equipment operates with low noise, which will not affect the surrounding environment or personnel, making it suitable for quiet working scenarios.

Adjustable speed and stability: It can meet the demand of different air volume by adjusting the speed, the inlet and outlet are linear, the air volume is large, the vibration is small, and the operation is stable and reliable.Long life and easy maintenance: material anti-aging, high temperature (part of the scene) and low temperature, no wearing parts, low maintenance cost.
