670 Auto Vent ChartMaid-O’-Mist’s new No. 670 forged brass Auto-Vent is an ideal automatic vent for hydronic heating applications.  With the highest capacity rating available for a forged air vent in the 35-50 psi range, a No. 670 Auto-Vent will relieve air much faster than any comparable automatic vent.

Quality Construction

The highly efficient No. 670 Auto-Vent is precision machined from forged brass into a one-piece body and bonnet.  It is designed for quick installation and trouble-free operation even in the most demanding applications.

Cleanable & Renewable

No. 670 Auto-Vent features a self-cleaning assembly which automatically flushes debris free from the internal shut-off mechanism as it purges air from the heating system.  The valve can be disassembled for a thorough cleaning if necessary, and the shutoff elastomer can be reversed if the original surface is damaged or worn to provide an entirely new surface.
