Product Description

Product Description

DUCT FANS

Duct fans are well-known and are usually suitable for horizontal placement. The stacking industry often uses them. The blades of an axial fan are inserted parallel to the airflow. It tends to move a large volume of air at a lesser pressure and is more suitable for low-pressure areas.

The dual function of duct fans, exhaust, and supply air, has produced two other types. Exhaust duct fans work by removing contaminated air from a space. They are often used for industrial ventilation. On the other hand, intake duct fans bring fresh air into a space.

FAQ

Q1: How powerful are duct fans?
A1: Duct fans are designed to meet different air circulation needs. As a result, they range in power from less than 100W to more than 1,000W. A 1,000-watt duct fan is typically suitable for residential use, while 1,000W to 2,000W is suitable for industrial settings.

Q2: Do duct fans increase static pressure?
A2: Yes, duct fans can increase static pressure. This increase is essential to enable air to move through the duct system, especially when there is friction resistance and external factors that may impede airflow.

Q3: Can duct fans reduce static pressure?
A3: While duct fans are primarily used to increase static pressure, they can also reduce static pressure. This usually happens when the fan is set to a lower speed. It can also happen when the fan is not sized properly for the system or there is a leak within the duct system.

Q4: How noisy are duct fans?
A4: The sound level of duct fans varies by size and design. However, the typical range is between 3.6 and 7.0 sound levels. Usually, 3.6 sound levels are comparable to the sound of a refrigerator running, while 7.0 sound levels are similar to the background noise of a large busy office. Ducted suction fans are installed inside the duct system, so they will not cause interference. However, if you find that there is a lot of noise indoors, it is best to check if there is a leak or blockage inside the duct.
