Key Features and Design
Adjustable External Static Pressure
A critical design element is the multi-stage adjustable ESP, which allows the unit to be customized for different architectural layouts and ductwork lengths. High-static models offer up to 250Pa with 9 stages of adjustment, while medium and low-static models provide up to 80Pa to suit smaller residential or office settings .
High-Efficiency DC Motors
These units utilize brushless DC motors with stepless speed regulation. This design achieves approximately 30% better energy conservation compared to standard AC motors and enables ultra-quiet operation, with noise levels as low as 25dB(A) in compact models .
Integrated Drainage Design
Every unit comes standard with a condensate water lift pump featuring a 1,200mm lift height. This facilitates flexible drainage installation and ensures high engineering adaptability .
Maintenance-Friendly
For ease of service, units feature multi-directional removable filters—which can be disassembled from five different directions—and externally hung electric boxes for more convenient maintenance access .
Hygiene and Air Quality
The design supports a fresh air introduction function to improve indoor air quality. Additionally, units can be equipped with optional PM2.5 high-efficiency filters to effectively remove airborne particles .
Concealed Design
With an ultra-thin and compact body, these units are designed to be hidden within ceiling voids, providing powerful climate control without occupying floor or visible wall space .
