Product Q&A
12 QuestionsQ: Is the air vent the same SKU: (419-1) in the 3/4" model and 2" model
Asked by Bob 9 years ago

Verified Reply- SupplyHouse StaffYes, each model in the VRTX series comes with the same Taco 3/4" Hy-Vent.
Q: Is the Taco cast-iron body suitable for use in open-loop hydronic heating systems, i.e. a heating system in which the heating water also serves as the house hot water supply. In other words, is this air separator suitable for potable water systems?
Asked by Alex 10 years ago

Verified Reply- SupplyHouse StaffThe cast iron air separator is not approved for use in open-loop hydronic systems due to potential for the corrosion of the cast iron.
Q: Can you replace the vent on this air separator?

Verified Reply- SupplyHouse StaffYes the replacement vent for this air separator is SKU: 419-1.
Q: The air valve on top of my air separator leaks. What is the difference between the 418 and the 419 Hy-vent? I have the old valve removed and can not find a model number on it. There is a big difference in price.

Verified Reply- PexSupply StaffThe 419 vents have higher pressure ratings than the 418 vents (maximum system pressure: 250psi vs 150psi; maximum venting pressure: 150psi vs. 50psi).
Q: The set up I have is that the pump is on the return line and pushes the water into the boiler would the separator sill work fine on the suction side of the pump?

Yes, the vortech will still work just fine. I have used the same setup on several jobs, although "pumping away" from the boiler is usually preferred option in most cases, because this setup ADDS to the static pressure in the system, entraining the microbubbles in the water, which will eliminate most of the more common air problems in modern hydronic systems.
My separator is on the push side and past the boiler prior to the valve manifold. My regulated feed line is also post-boiler, pre-separator. The system is a closed system--for the most part. Given all this, the source of air in my system was caused by two things: 1. The source/purge line and 2. A joint in one of zones started leaking and air got in the line. For the source/purge line, not a problem as the separator was right after the input line. For #2, the air had to be pulled to the pump, pushed through the boiler, past the source line (BTW--air would go up into the source/purge line then) to the separator. I had considered putting another separator in prior to the pump because hydro-pumps tend not to like air. Boilers don't care for air either. So, I think it would work fine. You may have issues with air from the source/purge line if it is post pump/boiler. Just my opinion
yes
Q: Do you need to install a blader type expansion tank to the bottom connection on the unit?
Asked by 14 years ago
Add your answer
Verified Reply- PexSupply StaffThe air eliminator does not have to go directly on top of the expansion tank, but it is usually a good idea to install them close together at the "point of no pressure change."
No you don't have to. I used the plug that came with the air separator. Then I attached my expansion tank elsewhere in my system because I didn't have room beneath it.
No the expansion tank can be in any pot in the system but you should install the water feed valve there
Q: hi I have a 008 taco pump and want to know if its ok to put the,, 1" Cast Iron Vortech Air Separator after the pump ( don't have room before the pump) thank you
Asked by sshhmmuueell 14 years ago

Verified Reply- PexSupply StaffYou really should place the air separator before the pump. There is a "point of no pressure change" just before the pump, and this is where the air separator functions optimally.
Q: Hello, where would this exactly be placed in a heating pipe system (ie, near the boiler supply, or return)? I have four series-loop zones in my heating system. If I place this air separator right before the branches, will it be effectiving in removing air from all four zones?
Asked by Amado 15 years ago

Verified Reply- PexSupply StaffNormally the air eliminator should be placed on the supply side between the boiler and the circulator.
Q: Hi would you recommend using this with 1 inch pex?
Asked by 15 years ago
Add your answer
Verified Reply- PexSupply StaffAccording to the manufacturer, the PEX tubing may not be able to support the weight of the VRTX unit. If the 1" PEX is T'd into a common header pipe, then you should be fine as long as the VRTX is installed on the header piping.
Q: are you able to use this for radiant tubing loop?
