This small wall-mounted bidirectional booster ventilation fan features a pure white, minimalist design that is moisture-proof and durable. It has two fans with high air volume for both exhaust and intake purposes. The digital display touchscreen is combined with remote control operation, allowing for adjustable speeds in multiple settings. It is a practical appliance for ventilation and air exchange in small living spaces.

The entire unit is constructed with thickened, flame-retardant engineering plastic, offering robust durability that resists deformation and aging. It is moisture-resistant and waterproof, making it ideal for long-term use in humid bathroom environments without mold or cracking. The sleek, rounded rectangular design features clean, sharp lines, while its pure white finish complements modern and minimalist interior styles. Equipped with a fine grille protective mesh, it effectively prevents debris from contacting the fan blades without obstructing airflow, allowing for easy dust wiping and maintenance.This compact wall-mounted exhaust fan is available in two sizes: 4-inch and 6-inch. With its sleek, pure white design, it effortlessly complements a variety of interior styles. Its small footprint saves space, and quick installation is achieved simply by cutting a hole in the wall. Equipped with a dual-fan pressure-boosting air duct system, it delivers superior ventilation efficiency, supporting both indoor exhaust and fresh air intake simultaneously—making it ideal for kitchens, bathrooms, walk-in closets, and other small spaces requiring effective air circulation.


Inside, a dual-turbine fan structure provides stronger air pressure and longer airflow reach compared to conventional single-fan models, enabling rapid air exchange even in tight, enclosed spaces. The unit supports bidirectional operation: running forward expels indoor cooking fumes, dampness, and odors outdoors, while reverse mode draws in fresh outdoor air, eliminating stuffiness and stale air. Multiple speed settings allow flexible control—low-speed mode ensures quiet, gentle ventilation for continuous use, while high-speed mode quickly removes steam after showers or kitchen grease.

A digital control panel on the side displays real-time ambient temperature, with clearly labeled function buttons. It can also be operated remotely using an included remote control, allowing users to adjust fan speed, switch airflow direction, or set timers—all without getting up, offering convenient, hands-free operation at home. The internal motor has been specially tuned for noise reduction, producing minimal vibration and operating quietly enough to avoid disturbing sleep or rest, even when used at night.

Optimized for slim depth, the fan fits into standard wall cutouts without requiring extensive ceiling modifications, making it easy to install in rental apartments, small homes, or renovation projects. Its waterproof sealing design effectively resists moisture intrusion, protecting the internal motor from bathroom steam and kitchen grease, thus ensuring long service life. Ideal for bathroom dehumidification, kitchen grease extraction, closet moisture control, storage room odor removal, and ventilation in closed-off study spaces, this compact yet powerful appliance is a practical solution for air circulation in residential small areas.
