AIR SUPPLY AND EXHAUST APPARATUS

摘要

PURPOSE: An air supply and exhaust apparatus is provided to naturally circulate external air to an indoor space without an additional power device by installing a linear venting line passing through a building in the ceiling of each floor. CONSTITUTION: An air supply and exhaust apparatus comprises a venting line (10), filters (20,40), and multiple vent holes (15). The venting line is installed inside the ceiling (1) of each floor and horizontally penetrates through a building. The filters are installed on both ends of the venting line and filter dust from external air flowing into an indoor space. The vent holes formed on the bottom surface of the venting line supply external air to the indoor space and exhaust contaminated internal air to the outside.
