What are the recommended fans for air conditioning and ventilation?

In the offices and homes where we spend much of our time, comfortable environments are maintained through air conditioning and ventilation.
Fans play a vital role in these air conditioning and ventilation systems, so it is essential to choose an appropriate fan for the application.
This article explains the characteristics of fans required for air conditioning and ventilation, specific usage scenarios in the office, and the types of fans used.

1. Fans used for air conditioning and ventilation in offices

Let's take a look at where fans are used in the office.

2. Fan characteristics required for air conditioning and ventilation

Quietness

In air conditioning and ventilation systems installed in offices and homes, fan quietness is a very important factor.
For example, in an office, people want a quiet environment so they can concentrate on their work, and loud fan noises can reduce work efficiency and even cause stress.
Selecting a fan with excellent noise reduction will help create a comfortable and productive space.

Waterproof

Waterproof fans are required for ventilation systems used in places with a lot of moisture, such as window frames and bathrooms.
The use of Splash Proof Fan that can be used safely even in wet environments leads to improved reliability.

Energy efficiency

In offices, air conditioning and ventilation systems are often used for long periods of time, making reducing power consumption an important issue.
Choosing a fan that consumes less power not only reduces costs, but also contributes to reducing the burden on the environment and helping to realize a sustainable society.

Splash Proof Blower

This blower has excellent waterproof and dustproof performance. Because of its high static pressure, it is suitable for intake and exhaust of equipment with high ventilation resistance.

Waterproof performance

Waterproof and dustproof with protection rating IP68

High static pressure

Ideal for intake and exhaust of equipment with high ventilation resistance

Reversible blow fan

The direction of the wind and the rotation speed can be controlled using a PWM signal. The wind direction can be changed with just one unit, which contributes to cost reduction and space saving.

Airflow direction	Rotational speed [min-1]	maximum airflow [m3/min]	maximum static pressure [Pa]	Noise level [dB(A)]	Power consumption [W]
Positive direction	5,450	2.10	285	49	3.0
Reverse direction	5,450	2.05	280	52	3.0
