Vent brands and adjustable options?

bipbap · January 27

So I have what I think are a bunch of leaky old air vents causing my water loss.

I've been usually replacing with Gortons but they get pricey and I still end up questioning whether I got the right size.
I know Maid O Mist aren’t highly recommended but I like that they come with adjustable openings and so I have the option to try out different sizes without having to buy a whole new vent.

Is there a recommended brand of adjustable vents like Maid o Mist that people use?
And either way, where are people finding best prices on these?

Just trying to shop around since I may need 8 or so.

The Maid-o-Mist vents aren't adjustable in the conventional sense, but they have removeable vent orifices, so you can change the venting rate. You can get a vent that comes with a set of orifices. https://www.amazon.com/Maid-Mist-ANGLE-STEAM-VENT/dp/B016PFFCX8/ref=sr_1_4

Oh yes that’s what I meant when I said adjustable- those ones that come with multiple size orifices.

Are these worth trying out in my situation?

I feel like I read not great stuff about Maid O Mist so wasn’t sure if there was another recommended brand with multiple size orifices.

I don't think anyone else uses that approach, but I've been using them for years and swear by them. The advantage to this approach is that, once you figure out what orifice size to use with each radiator, you can get a new vent and keep the same orifice, which is a life-saver when you can't find a new vent in the correct size. Also, if you decide you don't like the Maid-O-Mists, you can replace them with Gortons of the same sizes once you've got your system balanced.

I use MoM, it is in a 20 unit building with 92 radiators, in the last 5 years I have had to replace 2 vents that I installed, both failed closed.

im not a pro but i use the vent rite #1 and like them, they dont have interchangeable orifices but you can adjust them

Ventrite 1 is a great adjustable vent. It is on the slower venting side overall (0 - 0.158cfm @ 3oz as opposed to a Hoffman 1a 0.033 - 0.3cfm or Maid-o-Mist caps at 0.06 - 0.783) and an outstanding choice if you often want to really slow down a radiator. I personally don't think most any radiator ever needs more venting than the highest setting on the Ventrite. The adjustment seems more precise than on the Hoffmans. They are pricey but they are made right here in Michigan in Benton Harbor.

Supply House sells a pack of 5 different orifices fro MoM vents.

Just the orifices without the vent valve itself.

Vent Rite#1 is my top choice for adjustable ones if a customer wants that functionality. Ironically the supply houses in the Detroit area don't stock them, but they are made in state.

Hoffmans are just ok, I've had a customer that just wanted them all to match so we used those instead of Vent Rite.

MOM is the budget friendly option when we have a long list of items that need attention, but need to address balancing or a bunch of bad vents. I had a customer order some of these on their own and noticed they only came with one #5 , but if I buy them from my supply house I get a pack with different sizes in the box. If you go with these order a pack of extra orfices so you can balance your system.

If you want something a bit more fancy for your bedroom or living room Macon Controls makes a nice adjustable control, but they are pricey
