FFU stands for Fan Filter Unit. It is a self-powered, modular terminal air supply device with filtration capabilities.

Laminar flow ceilings are ventilation and purification systems that deliver filtered and purified clean air into an indoor space in a uniform laminar flow manner from the ceiling. Based on laminar flow technology, they purify the incoming air through high-efficiency filters, allowing the clean air to be delivered evenly downwards from the ceiling in a laminar flow pattern. This air flows through the work area at a constant speed and in a parallel airflow, rapidly expelling indoor dust and pollutants, thereby maintaining a highly clean indoor air environment.

The core function of HVAC goes far beyond temperature regulation; it lies in the precise control of air cleanliness, humidity, pressure gradient, and airflow direction. By intercepting particles and contaminants through high-efficiency filtration devices and in conjunction with a well-designed ventilation system, HVAC systems can create a stable, dust-free environment for production or experiments, preventing cross-contamination and ensuring product quality and experimental accuracy.

Temperature and humidity transmitters are devices used to measure and transmit temperature and humidity data, and are widely used in industrial production, environmental monitoring and other fields.

Sandwich panels are a composite material consisting of two layers of molded metal panels and a foamed and cured polymer insulation core sandwiched between the panels. They combine rigidity and thermal insulation, are easy to install, and have a short construction period, making them widely used in construction and other fields.

In industries with stringent environmental requirements, such as electronics, pharmaceuticals, and food, Class 100,000 cleanrooms act as an invisible yet robust defense, silently protecting product quality.
