    Controlling low air pressure

    I am looking for a device to control low air pressure, open at 2.0 psi, close at 3.5 psi. Any such device?

    Pressure Switch/Sensor - Look at well pump type pressure switch companies and inquire about your on/off pressure range.
    Tell me and I forget. Teach me and I remember. Involve me and I learn.

    You might use two valves in series. The first would open a 2psi and the second close at 3.5 psi. You could also combine an electrical with a mechanical valve to handle separate conditions.
