The No. 66, 67, 68 Auto-Vents® are float-operated vents for use on convector radiators, baseboard radiation and radiant panels. These are designed to be used in space that is limited and can be installed in trouble spots previously neglected or improperly vented. No air chamber is required. The No. 66, 67, 68 Auto-Vents® are designed for systems with pressures up to 50 lbs.
The No. 9AS Shortstop is an Automatic Shut-Off that saves hours when changing out Maid-O-Mist® vents with 1/8 male connections. This accessory is a spring-loaded shut-off that stops the flow of water automatically when the vent is removed and re-opens when a new Maid-O-Mist® vent is installed. With a Shortstop in place, it is no longer necessary to drain the system to switch out vents.
In situations where safe waste is required by law or areas particularly susceptible to water damage, the No. 7A Connector is used to connect 1/4 copper or plastic tubing to the venting port of Maid-O-Mist® vents. In this manner, any spray caused at system start-up or leaking caused by scale in a system can be safely directed to a drain.
