Introducing KEIYO's New Fan Diffuser AN-S176

On June 24th, 2026, KEIYO Engineering Co., Ltd., based in Shimbashi, Tokyo, will launch the innovative AN-S176, a car-mounted fan diffuser that promises to change how we experience fragrances in our vehicles. This compact device allows users to simply insert commercially available can-type air fresheners, automatically dispersing scents throughout the air space with the help of a built-in fan.

Solving Common Concerns

One of the most common complaints among drivers is the limited reach of air fresheners in cars. Many have noted that without the air conditioning running, fragrances often struggle to fill the space. Recognizing this issue, KEIYO has developed the Fan Diffuser to ensure a consistent and powerful aroma spread. The device uses USB power, eliminating the need for batteries and simplifying its use in a variety of settings such as cars, homes, or offices.

Launch Celebration and Discount

To celebrate the launch, KEIYO will offer a limited-time special promotion. From June 24th to July 1st, customers can take advantage of a discount coupon worth 500 yen off, providing an excellent opportunity to try this new fragrance experience at a lower price.

Key Features of the AN-S176

1. Compatible with Can-Type Air Fresheners

The fan diffuser is designed to accommodate standard can-type air fresheners (up to approximately W70 x H41 mm). By inserting the chosen fragrance, the built-in fan rapidly and evenly distributes the scent, filling the vehicle or room effortlessly. The operation requires just four simple steps: 1. Remove the top of the unit; 2. Insert the air freshener; 3. Replace the top; 4. Connect to USB power.

2. Three Speed Settings with LED Indicators

With an easy-to-use control button on top, users can toggle between three fan speeds: low (indicated by a blue light), medium (green light), and high (white light). This visual feedback allows for quick adjustments without confusion regarding the current setting.

3. Automatic Activation and Memory Function

The AN-S176 automatically turns on with the vehicle’s ACC power, eliminating the need for manual activation each time you drive. Additionally, it features a memory function that remembers the last fan speed used, resuming that setting when the engine is restarted.

4. Compact and Convenient Design

Measuring approximately φ81 x H120 mm, the diffuser fits snugly in most vehicle cup holders. The USB Type-C charging ensures versatility, as it can be used in various environments outside the car, such as at your desk or home. Thanks to its battery-free design, users do not have to worry about changing batteries or unexpected outages.
