How An Air Separator Works | Emerson Swan

Bruce Marshall demonstrates the negative effects of air inside a hydronic heating system and the benefits of installing a Taco 4900 air separator.

Excellent video, thank you for teaching this vital information, making us better in this field.

[@patrickkattan2234]

Thank you for this nice and informative demonstration; I really liked it.

[@kasanay]

Nice, informative video. I never knew about the 18" rule. Thanks for the info.

[@teamdrummond6915]

Superbly done. Thanks!

[@johncoppock3823]

Great video 👍 thanks. Didn't know about the 18 inch rule

[@qut8588]

Thank you, very informative. Is it normal to hear the hissing sound from the air separator?

[@MrPromerican]

Good demo..thanks

[@Jorge.O85]

Thanks a lot ! good demonstration. 👍 I need to run to Home Depot and get the vent air valve !!! 😮

[@MrPromerican]

Good demo

Gracias!!!👍

[@afiaiqbal6025]

Thank you

[@miketomas8564]

Thank you for this demonstration. But big question: Do you have a similar product for the diesel fuel line for the hydronic heater? I am getting air bubbles into the burner and flaming out, so I need to A: Fix the actual problem, but B: would like to add an air separator close to the fuel input of the burner to further reduce flame out. We are talking 10psi with 1/4 ID line...

Try a tigerloop

thanks a lot

Whats the stuff at the bottom of the eliminator again? Does it ever clog thete?

[@Parkerized1]

If you don't use obsolete air scoops, made for ancient 190°F atmospheric boilers, you don't need to know "the 18" rule". We love the Taco 4900 series Air Eliminator!

[@SandMan50Kal]

Hey Morgan. Is the air separator such as this one necessary?

[@billiam6461]

Where does the air go? Does the "air scoop" eventually fill up to where there is no more room to take bubbles out of the system?

[@solace001]

He didn't talk about it, but you can see a white float at the top of the water line. That's attached to a linkage which is attached to a discharge valve. When it's full it releases the air. Think of it like a toilet flushing, but the air goes and the water stays.

Where can i find that pipework it looks awesome! lol

[@enrikd3996]

Whats the advantage of a air eliminator

[@user-sm9hh9hz8j]

Good

[@l.crossjr]

How it an air scoop tested?

[@smiert13]

Air needs 18 inch to rise :D I can clearly see air bobbles go on the top almost immediately (2-3 inch) after that elbow :D

[@dpt4402]

the display is a poor example due to the pipe size and water velocity. With larger piping typical boiler trim you need to be further back from an ell.

[@smiert13]

@@dpt4402 Just stop it... I'm plumber for many years and installed air scoops 4-5 inches from elbow, works perfect. Is it as efficient as 18"? Probably NO, but if you don't have room, 4-5 inches does the job with no problems, takes little bit more time but does the job. I know, because I service same boilers later on and there is no air what so ever! Bigger pipe creates even less turbulence with the same circulator because water moves SLOWER in bigger pipe...

[@dpt4402]

@@smiert13 I have no doubt that you and your customers are very proud of your work. But from the experience of fellow trades person who dates back to when 50/50 was a thing there are instances that is not the best practice. The use hot water boilers are somewhat regional the introduction spriovent addressed the challenges of these hydronics as an example older multi story housing that has a far exceeding height between the boiler and the top radiation typical in New England or the introduction of zoning with multiple circulators creating high velocity scenarios. As very rarely a boiler trimmed in a 18 inch gunner. While it is true back in the day everyone used a cast iron scoop, they also walked around with a radiator vent key along with the home owner.

[@manofweed1]

Good idea, but a proper system shouldn't have air in the first place ?

[@harryschrysan3183]

There is always air during the commissioning and during repairs/maintenance. In a perfect world once you fill it up you should never have air again after a week or so.

[@alanhorrison6735]

all your product have been tested like this before it goes into market? people wont be concerned about the quality ?

[@jamesharrer9971]

That ain't a pump dude---it's a circulator!!
