Product Description

Step into a perfectly climate-controlled environment with the S3 Stainless Steel Series Air Curtain. Designed to meet the rigorous demands of high-traffic commercial spaces, this unit acts as a powerful, invisible shield over any entrance. The moment the doors open, a robust, high-velocity cascade of air sweeps down, effectively dividing the interior and exterior into two distinct temperature zones. This seamless curtain of air not only preserves the crisp, cool conditioning of summer or the cozy warmth of winter but also acts as an impenetrable fortress against street dust, flying insects, and noxious exhaust fumes. Crafted with a smooth, cool-to-the-touch stainless steel exterior, the unit exudes a modern, minimalist aesthetic that effortlessly integrates into upscale architectural designs. Beneath its polished surface lies a meticulously engineered pure copper motor driving a centrifugal fan, emitting a steady, reassuring hum that blends into the background while delivering unparalleled airflow. By preventing energy loss and maintaining pristine indoor air quality, this air curtain significantly reduces HVAC operational costs, making it an indispensable asset for facilities focused on long-term efficiency and superior occupant comfort.

▍Product Advantage

Elevate your facility's operational efficiency and environmental control with our meticulously engineered air curtain. Every component is selected to deliver maximum performance, longevity, and user satisfaction, making life more comfortable inside.

  • Uncompromising Thermal Separation: Generates a high-speed air current that acts as an invisible door, locking in cool or warm conditioned air and drastically reducing electricity expenses.

  • Comprehensive Environmental Shield: Efficiently blocks outdoor pollutants, providing excellent dust and insect-proofing while protecting against smoke and noxious fumes.

  • Accelerated Air Circulation: Promotes healthier indoor air quality by continuously moving and purifying the air within the entrance zone.

  • Whisper-Quiet Operation: Utilizes an advanced fan design to produce immense air pressure with minimal vibration, keeping noise levels unobtrusive.

  • Seamless Integration: The flat, low-profile design ensures the unit remains visually appealing, perfectly complementing the sophisticated interiors of modern commercial establishments.




Advanced Engineering & Design Dimensions

Our engineering team has meticulously refined every aspect of this air curtain to meet the exacting standards of large-scale commercial procurement. From the exterior finish to the internal mechanics, the S3 series is built for uncompromising performance.


Material & Design

Constructed with a newly developed flat stainless steel cover, the unit boasts a rugged, rust-proof exterior that is remarkably easy to clean and maintain. Its sleek, minimalist design language perfectly matches the sophisticated decor of high-end restaurants, luxury hotels, clubs, and modern commercial buildings, instantly elevating the entrance's aesthetic appeal.


Core Power & Energy Efficiency

At its heart lies a high-performance pure copper motor coupled with a centrifugal airflow fan, delivering a formidable air velocity of up to 20m/s. This robust airflow effectively halts indoor-outdoor air exchange. For specialized environments, an optional DC motor is available, offering superior adaptability to high-humidity and corrosive conditions while further reducing manufacturing costs and operational energy consumption.



Specifications & Installation Adaptability

To accommodate diverse architectural layouts, the series is available in six distinct lengths ranging from 920mm to 2000mm. The standardized, compact cross-section (212x225mm) streamlines the installation process, allowing multiple units to be seamlessly aligned side-by-side to cover exceptionally wide entrances with ease.


Smart Control & Convenience

Operation is effortless with the standard two-speed upgraded remote control, allowing users to switch between high and low speeds freely. For ultimate automation, the system supports an optional magnetic door switch (Auto ON/OFF). This enables a seamless "start upon opening, shut down upon closing" linkage with both weak and strong electricity doors, significantly enhancing daily convenience and maximizing energy savings.


Environmental Purification & Comfort

An optional high-density filter net can be integrated into the air inlet to filter the air, trapping dust particles, bacteria, and other unclean objects before they enter the facility. Despite its immense power, the acoustic engineering keeps operational noise as low as 49dB, ensuring the commercial environment remains peaceful and comfortable for guests.
