Circular Inline Duct Fan

Circular duct fan is characterized by small size, light weight, easy installation and low noise. Circular duct fan is an ideal ventilator with perfect combination of performance and appearance. The new design of the casing and the ingenious cooperation between the backward tilting centrifugal impeller bring the gas hydrodynamics into play to a certain extent, and its shape is compact and very practical. The circular duct fan provides source power for air supply, exhaust, return and air purification treatment.

Overview

Principle:

High wind pressure can be connected to dozens of meters of pipeline, a duct fan control multi-area centralized ventilation, commonly used in indoor ventilation or pipeline pressurization. Circular duct fan can be connected to both sides of the same size pipe, one side of the air inlet and the other side of the air outlet. Circular duct fan can be selected according to the size of the original diameter of the pipeline, but to ensure that the main pipeline is large enough, the sub-pipeline allowed to be smaller, the duct is too thin will affect the performance of the fan.

It can also be calculated according to the area of the space multiplied by the height of the volume of the space, the room, office ventilation per hour air changes 2-3 times, the bathroom air changes 8-10 times, public places will be in accordance with the number of people in the activities and the quality of the air, the general air changes 2-5 times.
