It is an air intake filter that combines an insect-proof net and an air intake pipe installed on the outer wall.
【About the Product】 Aikyu's natural air supply vent utilizes the pressure difference between indoors and outdoors, making it possible to collect and absorb sound, which was previously unachievable. It shuts out harmful substances that affect human health due to dust PM2.5 and noise, providing a passive, energy-efficient, and eco-friendly solution for air purification and sound absorption. This is a patented technology that incorporates structures such as dust filters, dust-absorbing filtration devices, and airflow adjustment grilles. 【Features】 ○ Dust removal for PM2.0 and above; sound insulation of 30dB(A) and above ○ Compatible with buildings with wall thicknesses between 160mm and 650mm ○ Airflow adjustment grilles are also available ○ No electricity required, energy-efficient ○ Utilizes the pressure difference between indoors and outdoors For more details, please contact us or download the catalog.
