Not Really a Radiator Vent. What am I?

Long Beach Ed · February 5

I was born in 1952. No, I'm not a steam radiator vent.

Tiny steam trap?

Nope. Not a steam trap.

Vent for a Paul or other air-line system.

Is that one of those thermostatic radiator vents that is sort of a trv and a vent all in one?

Long Beach Ed · February 5

Not a Paul, air line or vacuum vent/trap.

Not a TRV or any temperature-selecting radiator vent.

This.

It's a Maid-O-Mist No. 95 Auto-Vent Humidifier. 1952.

Screwed into your radiator's vent tapping, it shared the system's refreshing steam with you via an asbestos filter.

Here's a photo of the insides (with the asbestos filter removed) :

Here's a the Patent illustration of what's inside:

A bad idea whose time has come… and gone, thank goodness! 😳

Probably could get away withit with the huge chunks of iron they called boilers in those days.

Gonna have to take a hard pass on asbestos filtration though.
