Spending 90 % of the time indoors, we breathe tons of air each day. Therefore for breathing fresh quality healthy air, ventilation is a must in every building. Proper ventilation helps in the extraction of the foul stinking smell and provides fresh breezes of air into the building. If you don’t have adequate ventilation indoors, the following will be prone to many hazardous problems.
What Are The Adverse Effects Of Improper Ventilation?
Radon gas is an odorless and colorless gas, emitted when the decay of uranium occurs. Radon gases are one of the significant lung cancer-causing gases. This problem commonly occurs in the buildings near water treatment facilities, cases, and mines.

Helps in the prevention of respiratory disease and Asthma
Many respiratory infections are caused similarly due to either allergy or not breathing in a reasonable amount of Oxy-rich air. Pollen, dust mites, mold spores are extremely set efficient to germinate under dampened and musty humid conditions. These conditions then lead not only to serious respiratory diseases like asthma but skin disease like eczema too.
Increase in the VOC concentrations
VOC (volatile organic compounds) are those harmful emissions that are emitted from our household chemicals such as polish or coats on furniture, low-grade plastics, etc. The bitter truth here is that it is absurd to remove VOC from our houses, but we can lower the concentrations by installing a proper ventilation system.
Some of the other drawbacks of improper ventilation are an increase in condensation inside the building and problems in removing the air allergens and pollutants.
How To Choose The Perfect Extraction Fan System For You
Now the time has changed, modern buildings which are airtight and highly insulated need advanced solutions, which are extraction fans.

To Choose The Right Extraction Fan For Your Need, You Should Know About The Basic Parameters:
Fan model
Fan location
CFM - cubic feet per minute
SP – Static pressure
Extraction fans are most needed in the wet rooms, also known as the places in the house where there is a regular flow of water from taps. Those would be bathroom, kitchen, and utility rooms. Therefore, choosing an extraction fan for a wet room is always crucial in terms of adequate ventilation. As per the latest building regulation laws.
These Laws Provide Us With The Minimum Flow Rate Of Extraction Fan To Be used
Kitchens – 60/ sec generally, 30/ sec where there is a hob next to the extractor fan.
Utility rooms – 30/ sec
Bathrooms - 151/ sec
Toilets – 61/ sec
Different Extraction Fans Are There
Axial Fans – These fans are simply those models in which air moves on the same axis for the account of a power source. Axial fans are probably the oldest yet the most widely used fans. Blade in the fan causes the pressure difference and it provides airflow. Axial is ideal for smaller areas and is highly effective in moving high volumes of air.
Centrifugal fans - These extraction fans circulate the air into circular motions, with the accompaniment of traditional centrifugal forces. Centrifugal fans drag the air through the ducts and tubes to provide a robust and stable airflow. Centrifugal fans are more efficient than axial ones.
Mixed Flow fans - Also known as diagonal fans, these fans are low volume high-pressure fans. A mixed flow fan has normally two-bladed; these blades are designed as two specific designs to make it more productive. Mixed flow fans are considered a better option in terms of size, space, and better yielding than both axial and centrifugal fans.
Ending words – There are no one-size extraction fans; therefore, one should always look for alternate solutions. There are certain factors while doing it also, the location where it is going to be placed, length of the duct, and if it is providing you the best and ideal solution.
