Description for Taco 435-5


The special design and internal baffles of Taco Air Scoops slow water velocity to separate the air from solution. Thanks to this design, Taco Air Scoops efficiently remove air to provide noiseless, air-free hydronic heating, cooling or combination systems.
Taco Air Scoops also provide an economic way to integrate air elimination by the connection of either a plain steel or diaphragm expansion tank.
Features Include:
One-Piece, Cast Iron Construction
Engineered Baffle to Separate Air from Water
Never Requires Servicing
Maximum Operating Pressure: 125 PSI (862kPa)
Maximum Operating Temperature: 300 degrees F (135 degrees C)
Recommended Flow Rate: 4 ft./sec.
Maximum Flow Rate: 8 ft./sec.

Connection Type: Threaded
Body Type: Cast Iron

Comments about 1" Air Scoop:

Installed a 30 gallon hot water tank for use as a buffer tank on a high efficiency boiler. Installed an air vent on the top of the tank thinking that would take care of air in the system however, the zone pumps pulled enough volume that the air bubbles were pulled away from the vent and into the zones. (Note: system already had an air scoop with expansion tank and vent but, due to location, it was not effective in eliminating air in the new buffer tank and zones.) Added this air scoop to handle the tank and zones. Works well and should handle any air that developes.

Originally purchased a 1" SharkBite Coupling to make assembling everything easier by reducing the amount of soldering required. Before assembly I descovered that SharkBite also makes a 1" Male Adapter. Purchased 2 of those and was able to eliminate soldering completely, a big help on a system that already has water in it. Total time to put Hi-Vent and adapters on the air scoop, drain the system down a couple of gallons, disconnect a union, measure and cut pipe in 2 places, reconnect the union, install and hang the scoop and screw in an expansion tank was probably 20 minutes. Refilled the system, started the pumps and no air problems since.

this air scoop is the best, and you leave the cap loose and walk away it's in auto and bleeds the air 24-7.

  • 1-1/2" Air Scoop

    Q:

    I do not have room for 18" on either side of this item. What kind of impact on functionality would I experience if I deviate from this recommendation?

      A:

      Probably minimal impact, but keep in mind that taco will problably not
      guarantee the component's performance. Put most of you're available
      straight pipe on the inlet side of the scoop though, and make sure to
      install a good quality auto air vent at the top with an inline ball or
      check valve for servicing without having to depressurize the entire
      system. Also make sure the system you are installing this in is a closed
      loop system because it is cast iron.

      A:

      The scoop should still be able to get some air out, but not as much as it would with the full 18". You could also consider an air eliminator in the style of a Taco 4900 or Spirotherm Spirovent. These use metal bearings rather than baffles to remove air bubbles, so there is no 18" straight-pipe requirement.

      A:

      You'll probably get a lot of air knocking around your system which will cause poor circulation of your hot water

  • 1" Air Scoop

    Q:

    Can the air scoop be installed on the boiler (primary) loop ... or does it have to be installed on the secondary (lower velocity) loop?
    Asked on 6/1/2012 by RG from New Hampshire

    • VERIFIED BUYER

      A:

      The air scoop should be installed on the supply side directly off the boiler. You should also put the expansion tank and water fill in the bottom of the scoop. This will release the air that is inherently in the water supply as the boiler fills. This is the best location as this is the point of no pressure differential in the system and will limit the amount of air in the system.

      A:

      I am in no way an expert on boiler systems. I installed mine in the retun of the primary loop with an automatic vent on top. This seemed to eleminate the air in the system that I could not get rid of by other means. Good luck RG.

    Q:

    What's the difference between an air scoop with a hy-vent and a spirovent
    Asked on 12/16/2011 by Anonymous

    2 answers

    • A:

      "The main difference between an air scoop with a hy-vent and a Spirovent is the air elimination process. The standard scoop/hyvent uses a different air elimination process than the Spirovent and other micro bubble type air scoops. Standard air scoops rely on the air rising, and being captured by a vent, whereas air scoops with micro bubble technology collect the micro bubbles in the air and convert them into macro bubbles that eventually float up to the venting area."

    • CUSTOMER CARE

      A:

      They remove air from the system in different ways. Air scoops have specially-positioned blades that direct air bubbles to the air vent. They work best when straight piping runs precede the air scoop. Spirovent air eliminators use pall rings to "scrub" air from the system.

      You always want the air scoop on the suction side on your pump. That is the point of no pressure change.
