"How far can fans become flat?" - A new concept in ventilation equipment that blends into the space! Free ventilation calculations available with next-day response at the earliest.

The "FLAT FAN" is a ventilation system that pursues a "flat design" that naturally blends into indoor interiors. It suppresses the assertiveness typical of conventional exhaust fans, achieving a clean finish that seems to integrate seamlessly with the wall. We offer two types depending on the application: a type that can be installed without making holes in the exterior wall, and the "Flat Fan Direct" type that penetrates the wall. You can choose according to your installation environment without compromising the exterior design of homes or stores. Furthermore, thanks to its unique centrifugal fan structure and high-performance dual centrifugal fans, it achieves both large airflow and quiet operation despite its compact size. It is effective not only for 24-hour ventilation but also for odor control in shoe closets and alleviating heat buildup in attic storage. 【Features】 1. A design that harmonizes with interiors 2. High-performance dual centrifugal fans ensure the reliable expulsion of indoor polluted air 3. Quiet yet powerful airflow, excellent energy efficiency with low power consumption 4. Easy filter replacement with a magnetized front panel 5. Removable and washable centrifugal fans keep it always clean *For more details, please refer to the materials available for download from the "Download Catalog" section. Ventilation calculation documents can be requested from the "Contact Us" section.

A novel design that doesn't look like a ventilation fan.

Sahara Co., Ltd. will launch the new design ventilation system "New Flat Fan" on September 3rd.

  • Product news

Sahara Co., Ltd. (Headquarters: Iwate Prefecture, Representative Director: Yoshiki Sahara), which boasts the top market share in Japan for ventilation sashes in the OEM business, has launched the residential 24-hour ventilation systems "New Flat Fan" (ventilation layer type) and "Flat Fan Direct" (wall-penetrating type) nationwide starting September 3, 2025. The newly revamped New Flat Fan, developed in collaboration with the Yoshitaka Watanabe Laboratory at Tohoku University of Art and Design's Faculty of Design Engineering, is a next-generation ventilation system that combines a sophisticated design harmonizing with interiors and high energy-saving performance. In recent years, the trend in residential design has been moving towards balancing "design" and "comfort." However, previous 24-hour ventilation systems have focused solely on functionality, presenting challenges in harmonizing with living spaces in terms of design. In response, Sahara Co., Ltd. has developed a new model, the "Flat Fan," which is a "ventilation fan that doesn't look like a ventilation fan," completely renewing its design, functionality, and maintenance aspects. ◆ Product Features 1. Minimalist design that blends into interiors 2. Comfortable ventilation with high-performance double squirrel cage fans 3. Achieves both quiet operation and energy-saving performance 4. Improved maintenance 5. No need for drilling holes in exterior walls

Sahara began with the establishment of Sahara Glass Store in 1956 and, since realizing the importance of ventilation, has focused on the manufacturing of "air supply vents installed in windows" and the research and development of "shape memory alloys" that are components of these vents. Currently, we are primarily engaged in OEM business for sash manufacturers and are proposing "window ventilation systems."
