Ventilation in the bedroom is important! Permanent natural ventilation system for the bedroom (rainproof, dustproof, soundproof).

Avoiding sealing with natural ventilation for infection control! We realize healthy and refreshing homes with permanent natural ventilation systems equipped with rainproof, dustproof, and soundproof functions.

Is the ventilation in your home's bedroom sufficient? The "Permanent Natural Ventilation System for Bedrooms" proposed by Soundproofing Technology is a new concept in ventilation equipment that prevents micro-level oxygen deficiency in residential bedrooms. A fundamental condition for maintaining health is constant exposure to air, which contains a mixture of gases with 20.94% oxygen. The lungs, which supply the necessary oxygen to the blood flow of internal organs, function optimally when activated. The bedroom space becomes a micro-level oxygen-deficient area as the oxygen is converted into carbon dioxide and water vapor through respiration, resulting in increased demand for the lungs to supply the oxygen needed for bodily functions. ■ Features - Ventilation can be achieved without opening or closing windows. - With an opening rate of over 90%, there is minimal airflow resistance. - Completely rainproof and dustproof structure, requiring no electricity. * Installation is possible in wooden houses or apartments if functionality is prioritized. Please consult us for details on installation methods. * Snowproof and soundproof functions are also available if needed. [Patented in Japan, Sri Lanka, Malaysia, and the Philippines.
