Introducing the Square Flow 150: An Innovative Ventilation Solution for Modern Homes

The Launch of Square Flow 150

Nippon Jukankyo Co., Ltd., headquartered in Tokyo, is excited to announce the arrival of its new natural air intake vent, the Square Flow 150, set for release on September 22, 2025. Following the success of the φ100 size Square Flow, the introduction of a φ150 variant aims to increase design flexibility and significantly enhance the comfort of residential spaces.

Importance of 24-Hour Ventilation

In today’s energy-efficient homes, maintaining clean indoor air is essential for residents' health. However, during the operation of kitchen hoods, a vacuum can form inside the house, particularly in tightly sealed homes. This situation can lead to heavy entrance doors or unintentional air infiltration from gaps. The Square Flow 150 addresses these issues with its larger aperture compared to the φ100 model, ensuring stable and efficient air supply.

Key Features of the Square Flow 150

1. Unified Design for Cohesion
The new Square Flow 150 is designed to match the φ100 variant, offering a harmonious appearance within any interior layout. Homeowners who utilize multiple sizes can maintain a consistent aesthetic throughout their spaces.

2. Quality Air Filtration
Equipped with effective filters, the Square Flow 150 efficiently blocks pollen and dust from entering the home, contributing to a healthier indoor environment. This feature is especially beneficial for those suffering from allergies, providing a significant comfort enhancement in daily life.

3. Durable ASA Material
Built to last, the Square Flow 150 utilizes ASA resin, known for its excellent resistance to UV rays and outdoor elements. This material helps prevent discoloration and degradation over time, allowing the vent to look great for years.

4. Increased Airflow Efficiency
The φ150 size greatly improves the air supply capacity. This is particularly useful in large living areas or atriums where fewer vents can still achieve effective ventilation. The design also alleviates negative pressure when the kitchen hood is in use, stabilizing the overall ventilation plan.

5. Sleek Finish with Concealed Screw Holes
The Square Flow 150 incorporates a thoughtful design that hides visible screws post-installation, contributing to a clean and tidy look that complements modern interior design.
