Maid O' Mist

The no. 1 steam vent is designed to vent the air from the main lines, as well as on longer runs (depending on building size). 1/2" x 3/4" combination vertical connection.

The no. 67 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. Auto-Vents are designed for systems with pressures up to 50 lbs.

The no. 72 series Auto-Vents are reliable, automatic air eliminating valves for concealed radiators, pipe lines, tanks and other devices where water or liquids are used for heating and cooling. They have proven to be the solution to problems that have confronted engineers and contractors in which air pockets or traps retard the free circulation of the liquids and reduce the efficiency of the system or appliance. The no. 7 series Auto-Vents air eliminators are made of brass and equipped with a self-closing, float-operated valve. The valve is equipped with a Monel metal spring and a Neoprene valve seat which is unaffected by high temperatures, oil and anti-freeze. No air chamber is required. The vent is regularly fitted with a patented cap that may be used as a check in case of a leak caused by core sand or scale.

The No 95 Push button Manual Vent provides the easiest way ever to manually vent a radiator. You do not need a key, coin or screwdriver. All you have to do is push on the insulated cap of the No 95 Pushbutton Manual Vent to release trapped air. Let go and the vent closes automatically. Great for tight spaces where vents requiring a key or coin are not practical.
