Do you know what kind of environment we live in?

Indoor air standard after installation of fresh air system

Professional research on indoor environment and control shows that indoor air pollution is 2-5 times more severe than outdoor air, and can reach up to 10 times in special circumstances. There may be over 400 chemicals and 900 different organic compounds in the home environment, and pollution comes from various aspects of life, including smoking, cooking, dust, pet dander, harmful gases emitted from household cleaning products and furniture, and indoor PM2.5 pollution.

Indoor formaldehyde concentration standard: Class I civil buildings have an indoor formaldehyde content of ≤ 0.08mg/m3, and Class II civil buildings have an indoor formaldehyde content of ≤ 0.1mg/m3

The standard for good home air: PM2.5 ≤ 35 μ g/m3 CO2 ≤ 1000PPM

Air standard for public spaces: PM2.5 ≤ 35 μ g/m3 CO2 ≤ 1500PPM

be vigilant! Indoor air pollution is 5-10 times higher than outdoor air pollution!
Indoor pollution sources are numerous, far more severe than outdoor ones

Main product categories for real estate fresh air application (positive and negative pressure)

Unidirectional flow machines can play a role in "indoor air health" (removing PM2.5, reducing CO2, and emitting harmful gases such as formaldehyde)

Negative press machineIt's for outdoor ventilation, fresh air comes in through the gaps between doors and windows

working principleIndoor polluted air is discharged from areas such as bathrooms and kitchens to the outside; Fresh air enters through the gaps in the wall.

Positive press machineIt is to supply air indoors, and the polluted air in the house is squeezed out through the door and the gaps between the doors and windows

working principleCreate a positive air pressure zone in the central area of the room, continuously delivering fresh air with high oxygen content to the room, thereby squeezing out polluted air from around the building and forming air displacement.

Two way flow and one-way flow fresh air system

Bidirectional flow fresh air system

The bidirectional flow machine adds an energy recovery system to the unidirectional flow machine, which recovers energy from the indoor exhaust air through a total heat exchange core. Plays an energy-saving role.

The effectiveness of the fresh air system

Passive room fresh air five constant guarantees

The Hall fresh air system can continuously supply fresh, clean, and oxygen rich air that has been purified and sterilized to the indoor environment while the doors and windows are tightly closed. It discharges polluted air from the indoor environment and recovers cold and hot energy while replacing the air. Ensure that indoor air is balanced in temperature, humidity, cleanliness, oxygen, and purity to create a healthy and comfortable indoor environment.
