A multi-function air vent is provided to reduce installation space and to facilitate installation work by adding valve, strainer and air separator functions to the air vent. A multi-function air vent comprises a body, a float(40), a strainer(50) and a valve(70). The body has a fluid inlet through which a fluid is introduced, an air outlet for discharging air included in the fluid and a chamber(11) for communicating the fluid inlet with the air outlet. The float is housed in the chamber and is lifted by a floating force of the fluid to open/close the air outlet. The strainer is provided at the fluid inlet to filter impurities from the fluid flowing into the fluid inlet. The valve is detachably coupled to the body to open/close the inlet.
