◆  The square diffuser has multi angle blowing, uniform air supply and large diffusion range. The blade angle air supply flow belongs to the attached (flat) type, which does not produce body induced air flow. The multi-layer cone divides the air into several layers and rapidly sprays air, so that the air in and the indoor air mix quickly. Fast and balanced air temperature and air flow velocity prevent dust wind.

◆  The outer frame and inner cone blade are detachable structures, which are easy to install and adjust. They are usually used together with the OBD miter gate and installed on the ceiling.
