HID Duct Series
- 18000 BTU
HID Duct Series
Concealed duct air conditioning with flexible ESP control, built-in drainage safety, and efficient comfort for residential and commercial spaces.
SLIM DESIGN
Designed to save ceiling space. In the slim-duct range, selected models offer a low-profile indoor unit with height as low as 190mm, helping installation in tighter ceiling voids while keeping a clean concealed look.
INNER HIGH LIFT PUMP
The built-in high lift pump can raise condensate water up to 1200mm. For smoother long-term drainage performance, the recommended drainage height is up to 800mm.
FLOAT SWITCH
A standard float switch adds extra drainage protection. Even if the pump fails or the drain line is blocked, it helps keep water under a safe level and reduces the risk of overflow or leakage.
FILTER
Hisense duct units come standard with a washable nylon filter. The long-life design reduces replacement frequency and allows dust to be cleaned off easily during regular maintenance.
1PA ADJUSTMENT
External static pressure can be adjusted through the wired controller with 1Pa precision, giving more accurate airflow setup for different duct layouts and installation conditions.
