ATM manufactured pressure sections are useful for pressurizing a waveguide system with air or other gases.  Units can be supplied either with a pressure gauge to monitor the internal pressure at all times, or without a pressure gauge.  Also available are Short length pipe-tapped pressurizing sections.  For more information feel free to call us and discuss your needs with one of our design engineers.
