    Wonder how much steam escapes trap through air hole?

    Probably so little that it condenses in the first foot or so of return from the radiator if it even gets there in the first place since the vaporstat and metering valve should keep it from getting to the return.

    In that case isn't this device superior to conventional trap? Unbreakable.

    My thoughts exactly jumper. No moving parts. Like a Hoffman loop.

    Vapor systems are superior to trapped systems if they are properly engineered, installed, and maintained. If some idiot cranks the pressure way up or installs a very oversized boiler it all goes wrong at once. The metering to the radiators also needs to be maintained when valves are replaced or emitters are added or moved.

    No disrespect to dead old men. Contractors are and were supported by suppliers and manufacturers who have to sell stuff to stay in business. Ideal steam heat doesn't require stinking traps or pumps. It is hermetic and has air evacuated mechanically.

    There are plenty of new buildings and renovations to sell equipment for. Having to maintain parts for old systems is far more of a burden than a profit center. There are a few companies that have made a business out of making parts for obsolete systems but that is a small niche business.
