In modern buildings such as commercial buildings, offices, factories or basements, ventilation systems play an essential role in ensuring air quality, safety and comfort for users.

1. What is a ventilation system?

This system helps circulate air between the inside and outside environment, providing fresh air, removing polluted gases, moisture, and unpleasant odors—helping to maintain a safe and healthy working and living environment.

2. Classification of ventilation systems

2.1 Natural ventilation

No mechanized equipment is required—take advantage of natural airflow through doors, windows, openings, or pressure differentials to circulate air. Economical but difficult to control flow and wind direction.

2.2 Forced ventilation (mechanical)

Use a fan to draw polluted air out, or blow fresh air inside, or a combination of the two for optimal airflow.

2.3 Classification by objectives and methods

In the direction of the airflow: suction, blowing, combining.
By dynamics: natural and mechanical.
By scope: overall and local.
By purpose: normal (daily ventilation), and incidents (such as smoke, toxic gases).

3. Main Structure of Ventilation System

A full system includes:
Air ducts and accessories (square, round, soft pipes, air valves, air outlets...)
Fan (axial, centrifugal) for suction or blowing of air
Air vents and dampers, sensors such as smoke, CO₂, differential pressure

4. The key role of the ventilation system

Air exchange, oxygen supply – prevent suffocation, increase operational efficiency.
Removes odors, moisture, and dirt to keep the environment clean and pleasant.
Controls humidity, prevents mold and microorganisms from growing.
Limit toxic gases (such as VOCs) to protect users' health.
Breakdown ventilation – creates safe pressure to help prevent fires and minimize risks in the event of a fire.

5. Diverse Applications of Ventilation System

High-rise buildings: Corridors, basements, and restrooms need ventilation to maintain fresh air.
Fire staircase area: Increase pressure to prevent smoke from entering, increase escape safety.
Factories and industrial parks: Eliminate residual heat, industrial dust, and harmful exhaust gases.
Barns, processing areas: Solve odors, ensure a clean environment, protect health.

6. Professional ventilation system installation process

Demand and field surveys.
Design & quotation based on building characteristics.
Make 2D/3D drawings, sign contracts.
Construction and installation of equipment in accordance with techniques.
Calibrate and measure for maximum efficiency.
Acceptance and handover.
Maintenance and post-construction support.
