There are two series of high-efficiency air supply outlets: I and II. Series I is in the form of replaceable filters, and Series II is in the form of disposable air outlets, both of which are downward air supply.

High-efficiency air supply vent series 1: This air vent is composed of high-efficiency filters, high-quality thin steel plates, aluminum alloy diffusion orifice plates, etc. It is easy to install, has reliable sealing, and can easily replace the filter. The takeover method can be top connection or side connection.

High-efficiency air supply vent series II: divided into ultra-thin type and thin type. All are disposable air outlets, which are easy to replace (you only need to remove the pipe clamp of the soft joint between the air supply pipe and the air outlet). This series is particularly suitable for purification air conditioning systems with limited ceiling space.
