BFU (Blower Filter Unit) is a type of air handling unit used in HVAC (Heating, Ventilation, and Air Conditioning) systems. It is a self-contained unit responsible for drawing in outside air, filtering it, and distributing it throughout a building. The main function of a BFU is to ensure that the circulated air is clean, free of contaminants, and at the desired temperature and humidity levels.
A BFU typically consists of a blower or fan that draws in the outside air, filters that remove particles, pollutants, and other contaminants from the air, and controls that regulate the airflow and temperature of the air being distributed.
The blower or fan in a BFU helps to create adequate airflow and ensure that the air is properly distributed throughout the building. It is typically powered by an electric motor and can be adjusted to different speed settings to meet the airflow requirements of the building.
The filters in a BFU play a crucial role in maintaining indoor air quality. They are designed to trap and remove dust, dirt, pollen, allergens, and other contaminants from the air before it is distributed. Common types of filters used in BFUs include fiberglass filters, pleated filters, and HEPA (High-Efficiency Particulate Air) filters. The choice of filter depends on the specific needs of the building and the level of air filtration required.
Overall, a BFU is an essential component of an HVAC system that helps maintain indoor air quality . Its ability to draw in and filter outside air ensures that the circulated air is clean and free from contaminants, promoting better indoor air quality .
