Product Description

High Quality 190x78mm Round High-Pressure Centrifugal Fan Low Noise Strong Static Pressure Centrifugal Fan

What is a centrifugal fan used for?

Because of the high pressure they create, centrifugal fans are ideal for high-pressure applications such as drying and air conditioning systems.

As all of their moving parts are enclosed and they also have particulate reduction properties that make them ideal for use in air pollution and filtration systems.

What is the difference between a centrifugal fan and a blower?

The casing in the center of the wheel uses centrifugal force to propel the air forward into the open.

A fan circulates air around an entire room or space. A blower circulates the air only on a specific or pointed area.

It is used less pressure to produce large amounts of gas.

Q6. How do we carry out quality control?
Usually, there are two ways to monitor reliability during the manufacturing process.
* Early Life Test This is used as a means of process control aimed at identifying any latent manufacturing problems and determining
the effectiveness of burn-in. Every day, 5 samples will be picked up randomly from one of the production lines for burn-in at
50C+/-5C for 24 hours.
*On-going Reliability Demonstration This is a longer-term program aimed at providing data that continues to demonstrate the
reliability of the product. 10 units per month are randomly collected from one of the production lines for burn-in for 168 hours at
50C+/-5C. Units are monitored and tested on daily basis. Failed units will be analyzed and corrective actions are taken where
