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

Avoiding airtightness with natural ventilation for infection control! We achieve a healthy and refreshing home with permanent natural ventilation systems equipped with rainproof, dustproof, and soundproof features.

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 designed to prevent micro-level oxygen deficiency in residential bedrooms. A fundamental condition for maintaining health is constant exposure to air, which contains 20.94% oxygen. The lungs, which supply the oxygen necessary for blood flow to internal organs, will function normally when activated. The bedroom space becomes a micro-level oxygen-deficient environment as the oxygen is converted into carbon dioxide and water vapor through respiration, resulting in the lungs working harder to supply the necessary oxygen 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 that requires no electricity. * Installation is possible in both wooden houses and apartments if functionality is prioritized. Please consult us for details on installation methods. * Snowproof and soundproof features are also available if needed. [Patented in Japan, Sri Lanka, Malaysia, and the Philippines.
