The Purpose of Good Ventilation
A Mechanical Ventilation Fan drives outside air into a building in order to improve the indoor air quality.
The primary goal of introducing fresh air into a space is to remove dangerous indoor air pollutants.
An Air Exchanger exchanges air between indoors and outdoors. It’s primary goal is the bring in fresh air from outside and exchange it with the stale inside air flow.
Foreign Reports show that when air conditioning or heating is used in a room, turning on the home ventilation fan can save 15%~35% than when not. This is a great choice for indoor ventilation and air exchange.
Purpose and Function of the Ventilation Fan
The ventilation fan was designed to eliminate poor indoor air and exhaust hot humid air, unhealthy particle matter and odor to the outside. The duct’s backdraft damper will effectively block waste gas in the common duct from flowing back into the room. In general, the ventilation fan can be applied widely in homes and public places.

The annual electricity cost of running a ventilation fan 24/7?
SUNON ventilation fans use energy-saving DC motors. When running a ventilation fan 24 hours a day, 365 days a year, the annual electricity cost is approximately 63 NTD (based on Taipower's standard household electricity calculation).
| Ventilation fan product comparison | Commercially available (AC motor) |  (DC motor) |
|---|---|---|
| Nosie | 35 db(A) | 32 db(A) |
| Power consumption | 25 W | 4.5 W |
| Maximum air volume | 85 (m3/h) | 120 (m3/h) |
| Energy efficiency* | 2.68 | 19.28 |

*The Taiwan Energy Label regulations set the energy efficiency standard for household ventilation fans at 7. (Energy efficiency unit: m³/hr/W @ 0.1 inch-H₂O/Watts)
IP25 Certified
The Eco DC Brushless Ventilation Fan is the only dust-proof/water-proof third-party IP25-certified by fan in the industry.
International Fire Safety Design
The Eco DC Brushless Ventilation Fan meets a high international fire safety design.
Sunon selects fireproof materials that conform to BSMI, UL 94V0 in Taiwan.
The housing also meets the USA requirement for building fireproof UL 94V-5VA, the highest flammability class.
Flammability classes are categorized as follows :
What is a Fresh Air System?
A fresh air system is an effective air purification device that circulates indoor air. It expels stale indoor air while introducing fresh outdoor air after undergoing sterilization, disinfection, and filtration. This ensures that the indoor environment is continuously supplied with clean, fresh air.Utilizing patented fresh air convection technology, the system achieves optimal indoor air exchange through independent air supply and exhaust mechanisms. It is equipped with a multifunctional purification system to ensure that the incoming air remains clean and healthy.
Fresh air systems are mainly categorized into exhaust-type and supply-type units. They can be installed in most indoor environments with ease, offering convenience and comfort. As an essential companion for a healthy home, a fresh air system enhances indoor air quality and overall well-being.
Function of the Flow2one
The Flow2one was designed to solve the ventilation and air exchange problems in your home in an intuitive manner. It can operate 24 hours a day, 365 days a year without opening windows to provide fresh natural air for your entire house. Moreover, It can eliminate toxic and harmful gas in it, improve the indoor air quality, and protect the indoor space from mildew. It safeguards the building as well as your health. The Flow2one system for home avoids dust, noise, flying insects due to opening windows. It also implements ventilation, energy saving, pleasant looking, silent effect in a better way than other ventilation devices. 
You don't need to open the doors and windows to bring in fresh air.
But can keep interior "climate" at a constant level.
What is the Flow2one?
The Flow2one can be mounted easily. Like a mini total heat exchanger, it can bring in regulated outdoor air into the indoor space through a PM2.5 filter and heat exchange. In this way, it balances indoor temperature and humidity and exhausts poor air to the outside. From now on, your home can exchange air without opening windows. And you can enjoy fresh air in it any time.
