Air ventilation

December 9, 2023 0 By kenyaagr

The general purpose of ventilation in buildings is to provide healthy air for breathing by both diluting the pollutants originating in the building and removing the pollutants from in addition to provide a continuous supply of fresh outside air distributes the air within the building or room. Remove or dilute airborne contaminants. Reduce potential fire or explosion hazards. Maintain temperature and humidity at comfortable levels.

Natural & mechanical ventilation

Natural & mechanical or hybrid systems are used to get more efficient air circulation by ventilation performance.

Like the lungs, buildings need to be able to breathe to make sure that fresh air comes in and dirty air goes out. Air indoors can build up high levels of moisture, odors, gases, dust, and other air pollutants. To keep the air safe indoors, fresh outdoor air is needed to dilute these indoor pollutants.

Roof slope also affects the performance of a naturally ventilated building. A proper roof slope enhances air mixing within the building and the ventilation rate through the building. An ideal roof slope is 4:12 (rise: run). A shallow roof slope (less than 3:12) or a flat ceiling will reduce air movement due to buoyancy forces. This results in stagnant air spaces, reduced ventilation rate, and increased moisture, heat, gas, and odor accumulation. A steeper roof slope can enhance the upward air movement due to buoyancy, which increases the air exchange rate. However, roof slopes greater than 6:12 can cause incoming air to exit the building before mixing with inside air, resulting in poor air mixing in the animal zone, and pockets of damp, stale, warm air. and Roof slope is 4 / 12 almost 30 Degree best between 22-28 degree recommended.

To provide good air quality, enough air needs to be brought in and circulated so that it reaches all areas of the buildings. For almost all buildings, windows and structural elements Many buildings need and have additional curtain systems and special venting that can remove the pollution they produce. These breathing curtains contribute to bringing in fresh air. Ventilation above needs to carry the air outside to avoid redistributing pollutants from inside the buildings.

Mechanical ventilation

Mechanical ventilation helps reduce indoor air pollution, but it works best if paired with keeping known sources of air pollution out of the building. For example, the only way to reduce the effect of secondhand smoke indoors is to not allow smoking indoors or near the entrances. Some cases you need efficient ventilation to get rid of the Emissions risks.

Types of mechanical ventilations are:

Like exhaust ventilation systems, supply ventilation systems don’t temper or remove moisture from the make-up air before it enters the house. 

    • Similar to combustion appliances, exhaust fans can remove too much air and cause negative air pressure. This can be dangerous and result in back drafting of appliances, leading to a buildup of deadly fumes including carbon monoxide.
    • Supply ventilation systems use a fan to pressurize a structure, forcing outside air into the building while air leaks out of the building through holes in the shell, bath and range fan ducts, and intentional vents (if any exist)
    • Balanced systems allow the use of filters to remove dust and pollen from outside air before introducing it into the house. Balanced ventilation systems are also appropriate for all climates.


Destratifiers are an effective means of ventilation all year round in a range of commercial and production settings. During the winter months, these ceiling fans can push hot air gathering at the top of a building down towards the floor. This prevents much-needed heat escaping from the room, resulting in energy savings of up to 30%.

Building owners, architects and HVAC specialists will benefit from the quality, efficiency, durability and a fast return on investment resulting from our installed and portable ventilation systems. From simple fans to ventilation units for residential, commercial and swimming pool areas.

In the summer, the air flow generated by a capable destratification system helps tackle overly humid environments by evaporating moisture below. This can create climates that are up to 4ºC cooler than perceived temperatures, making life more comfortable for people and greatly reducing the risk of condensation and mould growth.

In addition to making the climate within any space more consistent and comfortable, destratification fans help to continuously renew the air, reducing the concentration of fumes and bad odours that can affect work dynamics. They also disperse dust, protecting people with allergies and preventing it from entering machines and equipment.

Heavy-duty construction, balanced motor and thermal protection guarantees years of hassle-free use, as well as significant energy savings each year. If you are looking to ensure the best working environment for your teams and your bottom line, our solutions have you covered.

Green house Ventilation

Good ventilation is critical in maintaining an optimal growing environment and improves the overall efficiency of a greenhouse. It is essential for both good temperature and humidity management.
