1. Feature

1.1 Convenient for installation

1.1.1 The ceiling type can be easily installed into a corner of the ceiling even if the ceiling is very narrow

1.2 Three air flow speed: high/middle/low, double air guides.

1.3 Two direction auto swing (vertical & horizontal) and wide

angle air flow

1.4 Low noise, creates quiet and comfortable environment.

1.4.1 Electronic expansion valve, ensure precise flow control, as

well lower modulation noise when EXV operating.

1.4.2 Smoother airflow with less turbulence. Owing to the

multiple-blade fan and the air guide design, the airflow is

getting smoother and more comfortable

1.5 RM05/BG(T)E-A remote wireless controller which can set
