Abstract

According to an embodiment of the present invention, there are provided an exhaust assembly capable of uniformly forming an air flow in an exhaust step of discharging a gas to the outside, and a liquid processing apparatus and substrate processing equipment including the exhaust assembly. According to the present invention, the exhaust assembly that discharges a gas generated in a substrate processing process includes at least two or more intake ports into which the gas flows, a body portion that communicates with the intake ports and provides symmetrical paths for discharging the gas, a guide portion that is installed to guide a flow of the gas at the body portion, and an exhaust port from which the gas is discharged. The guide portion includes a flow guide that is installed to be adjacent to at least one of the intake ports and guides a direction of the gas to equally divide the flow of the gas, and a flow-rate guide that is installed around the intake port most adjacent to the exhaust port among the intake ports and is formed to reduce a cross-sectional area of a flow path of the gas.
