The ceiling‑mounted fresh air ventilator (ceiling‑type air handling unit) is a central air‑conditioning terminal unit that integrates fresh air exchange, air temperature and humidity control, air filtration and purification, and energy recovery. The unit features a concealed ceiling‑mount installation, suspended within the building’s suspended ceiling. It utilizes chilled water or hot water piping to provide cooling and heating, while simultaneously exhausting indoor stale air and supplying filtered outdoor fresh air. This system not only enhances indoor air quality in enclosed spaces but also regulates air temperature through heat‑exchanger coils, offering both ventilation and central air‑conditioning functions. It delivers energy savings, minimizes floor space occupation, and is widely suited for integration into fresh air systems in commercial, industrial, and large public buildings.
Our company manufactures bidirectional fresh-air ventilators—also commonly referred to as fresh-air ventilation units—which integrate mechanical supply and exhaust ventilation into a single system. They simultaneously facilitate two-way air circulation by bringing in fresh outdoor air while expelling stale indoor air, achieving efficient indoor–outdoor air exchange. Equipped with built-in fans and filtration systems, these units continuously deliver filtered, clean fresh air indoors while removing indoor pollutants such as carbon dioxide, formaldehyde, odors, and PM2.5, thereby addressing ventilation challenges in enclosed spaces and enhancing indoor air quality. Certain models featuring total heat recovery can also reclaim the cooling or heating energy from exhaust air, reducing the energy consumption of HVAC systems and balancing ventilation needs with energy efficiency. These products are widely used in residential, commercial, and industrial settings.
Our company’s haze‑removal fan—also known as a duct‑type fresh‑air purification fan or haze‑removal ventilator—is a duct‑mounted fresh‑air system that combines low‑noise air supply, air filtration and purification, and intelligent control. Building on the foundation of a quiet fan, it integrates an air‑filtration module that efficiently removes particulates such as PM2.5, dust, pollen, and allergens from outdoor air. At the same time, a low‑noise blower delivers the purified, fresh air into indoor spaces. Certain models also feature controller‑based functions like airflow adjustment and timed operation. Widely deployed in residential, office, and commercial settings as part of fresh‑air systems, this equipment serves as a core solution for improving indoor air quality during hazy and polluted conditions.
Our company’s ultra-quiet, bidirectional ventilation system is an advanced low-noise ventilation device that builds on the conventional bidirectional design, incorporating multiple noise-reduction technologies. Its key advantage lies in delivering highly efficient two-way air exchange while keeping operating noise at an exceptionally low level, making it ideal for environments sensitive to sound. It simultaneously performs bidirectional air exchange—introducing fresh outdoor air and exhausting stale indoor air—effectively addressing ventilation, formaldehyde removal, and odor control in enclosed spaces. Heat-exchange models further recover cooling or heating energy, reducing air-conditioning energy consumption. Unlike standard ventilation units, this product employs optimized ductwork, sound-absorbing and vibration-damping materials, and a low-noise motor to keep noise levels in the 22–30 dB(A) range even at the lowest settings. Operation is virtually imperceptible, ensuring no disruption to rest, work, or study, and seamlessly balancing superior ventilation with a tranquil indoor experience.
