How to buy good ventilation fans for family

For companies, businesses and households ventilation fans are an indispensable product. They play an important role in creating circulation, increasing new air for the living environment, especially enclosed spaces. A quality fan not only ensures performance but also provides a fresh atmosphere. So which is the best fan and how to choose the right product? Here are some of my experience in product selection, please refer to offline!

What is a ventilation fan?

A ventilation fan is a device that helps circulate air inside and outside the home. By using exhaust fans, the stagnant air and mold are removed. From there, the fresh air from outside will be brought inside. Fans are often used in locations where the air cannot flow by itself.

Why should use ventilation fan? 

Why should use ventilation fan

Why should use ventilation fan

1. Increase air circulation, reduce the risk of indoor pollution

For small, narrow apartments and low ceilings, the atmosphere is often stagnant. This has affected the health of the members living inside. At the same time, it reduces the ability to function, causes the ability to concentrate, even makes it difficult to breathe, increases the risk of chronic obstructive pulmonary diseases , asthma , ... Some furniture is also faster to fail in such environment.

At this time, the fan helps circulate indoor air, pushing stagnant air out and minimizing the multiplication of viruses. In addition, fans also help filter dust, fur ... indoors. From there, help increase the quality of life and protect good health.

2. Anti-"asphyxiation" condition when using air conditioner

Minimize the risk of indoor air pollution

Minimize the risk of indoor air pollution

On hot summer days, households and offices tend to use air conditioning. One of the must when using air conditioner is to close the door. But this makes the air in the room is not circulated outside, especially the old air conditioner.

If you stay in this environment for a long time, you will be at risk of suffocation due to lack of oxygen needed for the brain. At this time, a headache, dry skin and drowsiness will result. It is more dangerous when there are elderly people in the house which can lead to respiratory and cardiovascular diseases. And ventilation fan is the solution. Natural air will be brought in and provide necessary oxygen, contributing to ensuring the health of everyone.

3. Reduce the humidity in the bathroom

Did you notice that the wall in the bathroom is often black and mossy? That's due to the humid environment in that bathroom. And apart from those black walls, there are many types of bacteria that you won't be able to see with your eyes. Over time, they also cause the phenomenon of paint cracks, causing the bathroom interior to deteriorate quickly and directly affect health. At this time, using a blower will reduce the humidity and push the bacteria to the outside to return a cool atmosphere.

Classification ventilation fan 

Classification ventilation fan

Classification ventilation fan

There are many different criteria for classifying ventilation fans. Here are some criteria for your reference: 

1. Based on capacity 

  • Household ventilation fan is the type of fan used for function rooms, relatively small capacity. Fans are usually divided into wall fans and ceiling fans. Wall mounted fans are smaller than ceiling fans.

  • Industrial ventilation fan is the type of fan used for factories and factories. This type of fan has a large capacity, good durability. Industrial fans are divided into square wall fans, door mounted square fans, circular fans, axial fans and multi-bladed centrifugal fans.

2. Based on performance 

1-way fan

This product line has only one-way suction function to push out the old air out and bring new air into the room thanks to the pressure difference. Besides, the product can also be pulled in one direction from back to front to bring new air into the room and push the old air out thanks to the pressure difference.

2-way fan

2-way fans are equipped with both functions to both suck and blow in 2 directions. Therefore, the device is able to deodorize and provide clean air more efficiently. However, the price of the product will be much higher than a fan. But in return, the quality is very good.

3. Based on design

Based on the design, there are fans with curtains and fans without screens. 

Revealing the experience of buying ventilation fans

Experience buying ventilation fan

Experience buying ventilation fan

1. Determine the purpose of the fan and installation space

Normally, if you use fans for business purposes, for production, you should choose products with high capacity and high deodorization. At the same time, you should choose high-end products to ensure durability in the long run.

In contrast, for households you should prioritize the product line has a moderate size. This will save a lot of power consumption and bring high efficiency. If you choose the wrong capacity, it will waste installation costs and affect the aesthetics of the space.

2. Select the appropriate functional ventilation fan line 

If you have a need for household use, you should choose one-way ventilation fan. Because of their relatively low capacity, it is possible to save on purchasing costs and power consumption. But if you want to increase good circulation, you can also choose a 2-way fan, although the price is slightly higher.

3. Select your design

The type without screens will make it easier to clean but not suitable for installation in areas with lots of dust or insects.

Covered type will ensure safety for users. Moreover, the product can also block out dirt and insects. At the same time, the performance of the fan is also very good if you know how to use and clean fans properly.

Therefore, according to your experience, you should choose shielded fans to get the best utility.

4. Choose a brand of quality ventilation fan

Of course, a reputable brand and quality will give you the best choice. Therefore, you should consult your relatives and friends to be able to own a genuine and quality ventilation fan.

Instructions on how to install a ventilation fan

How to install the exhaust fan

How to install the exhaust fan

Placing the ventilation fan is also very simple. The specific steps are as follows:

Step 1: First, please disconnect the power before installing the fan to ensure safety for yourself 

Step 2: Please measure and measure the size of the fan correctly and then use a pencil to mark again. Then, cut the ceiling into an empty space to place the fan. Note, please measure it correctly!

Step 3: Next, install the ventilation fan parts on the ceiling one after the other, then in the correct order and then secure with screws.

Step 4: Connect the fan wire to the power source correctly and then wrap the tape around the connector to avoid power leakage. One thing you need to keep in mind is to check the wiring to make sure it is intact and safe. This can help you avoid unfortunate incidents.

Step 5: Finally, put a protective fan plastic on the ceiling for fans.

Step 6: Operate the fan to make sure your installation has been successful
