    Pneumatics

    Terry,



    Are you asking about pneumatic controls that are used on VAV boxes in common areas (hallways, etc) in apartment buildings? If so, what's on your mind?

    Pneumatic

    Hi Professor! This is a request from my tin-knocker based on him having seen/heard about a residential pneumatic zoned system installed on 3-4-5ton split units. So I'm starting my search here, good pool of info here! RJ, I did pneumatics in the 80's, lots of changes since then.

    Avoid Arzel. Temperamental, and prone to heavy service. In fact, I would avoid residential pneumatics altogether.
