Abstract
Disclosed is a vacuum system capable of realizing a simple, compact configuration using a filter cartridge. The vacuum system makes use of a container-shaped filter cartridge, which includes an intake port, an inflow port for compressed air, and a mounting port in a sidewall thereof, and a filter which is disposed in a space therein covered by a cap and filters air flowing in through the intake port. An ejector pump passes through the mounting port of the filter cartridge, is installed such that one end thereof is adjacent to or inserted into the inflow port, and includes a through-hole formed in a nozzle body so as to communicate with the space inside the filter cartridge. In the state in which the ejector pump is mounted, the filter cartridge is used as a housing providing a vacuum chamber or an enclosed space.
