永久技術研究所 List of Products and Services

【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 power-free, energy-saving, 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-saving ○ Utilizes the pressure difference between indoors and outdoors For more details, please contact us or download the catalog.

• Ventilation and Exhaust
• Filtration Equipment

Dust with a particle diameter of PM2.0 or larger is collected at over 70%, and the noise has a sound insulation performance of 30 dB(A), which is great news for the air supply vents of ventilation systems in general residences.

• Other assembly machines

The system air intake filter consists of a cover, insect mesh, air intake pipe, outdoor dust filter, dust and soundproof filter, indoor dust filter, ventilation grille, flange-mounted insertion pipe, and a structure that allows for outdoor drainage, combined with connecting bolts. It utilizes negative pressure technology that takes advantage of the indoor and outdoor air pressure difference and is affixed with sound-absorbing materials, functioning without power (no electricity), achieving over 70% dust removal for particles larger than PM2.0, and possessing sound insulation performance of 30 dB(A). This architectural ventilation equipment creates a gentle indoor environment and hygiene, protecting the health of residents. It offers eco-friendly air purification, sound absorption, and sound insulation. Airflow adjustment is also possible, and it is maintenance-free with excellent aesthetics. 【Features】 ○ Rounded tip, soft and lightweight spike type for safety ○ Made of lightweight plastic, easy to process and install ○ Durable weather-resistant material, usable semi-permanently ○ Maintenance-free and economical For more details, please contact us or download the catalog.
