Everything you need to know about air extraction ducts

Exhaust air ducts are an essential part of building ventilation systems and are used to maintain indoor air quality.

They are responsible for extracting stale air and replacing it with fresh air from outside.

In this post, we'll explain everything you need to know about exhaust ducts, including their function, types and materials used, and how to keep them in top condition.

Function of the air extraction ducts

The main function of air extraction ducts is to extract stale air from a space and replace it with fresh air from outside.

This is especially important in commercial buildings such as hospitals, offices, and retail stores, where proper ventilation is necessary to ensure the health and safety of the occupants.

They are also used in private homes to expel polluted air generated by the kitchen, bathroom, and basement.

Types of air extraction ducts

Air extraction ducts are divided into two types: rectangular and cylindrical.

Rectangular ducts are used in spaces with high ceilings or where it is necessary for the duct to be as straight as possible.

Cylindrical ducts are used for spaces with lower ceilings, such as those found at home or in offices.

Another important consideration for exhaust air ducts is the exit points. Ducts can be discharged through a hood, louver, or vent.

Materials used in air extraction ducts

Air extraction ducts can be made of different materials.

The most common are: galvanized steel, PVC and fiberglass.

Galvanized steel is the most widely used material in the industry due to its strength and durability.

PVC is an excellent option for buildings where a smooth and silent ventilation system is required.

Fiberglass is often used in spaces that are sensitive to corrosion, such as chemical laboratories.

Maintenance of air extraction ducts

The maintenance of the air extraction ducts is essential to guarantee their correct operation.

It is important to perform a complete cleaning of the ducts at least once a year. Accumulation of dust and other contaminants can reduce airflow and consequently decrease the quality of ventilation in the building.

Also, it's important to regularly inspect ductwork for leaks and other problems.

Air extraction ducts are a fundamental piece in the ventilation of a building.

From its basic function, to its design and the materials used, every aspect is important to ensure proper ventilation and quality air inside buildings.

For this reason, it is crucial to keep the ducts clean and in perfect working order, through regular inspections and cleaning.

If you are looking for a professional company to install or maintain your air extraction ducts, do not hesitate to look for experts in the area to have the peace of mind of knowing that your ventilation system works properly.
