  • Automatic float vent removes trapped air from hydronic systems
  • 150 psi maximum pressure rating suits residential and light-commercial loops
  • Brass body resists corrosion in water-glycol mixtures
  • 1/2 in female NPT expansion-tank connection simplifies piping
  • In-line configuration with 3 3/4 in port spacing fits standard layouts

Taco 3/4in Automatic Air Separator

The Taco 49-075T-2 is an in-line brass air separator built for hydronic heating and cooling systems. It uses a float-type vent to remove air from water or glycol circuits and carries a maximum pressure rating of 150 psi with a minimum operating temperature of 25 degrees F.

Installers needing reliable air removal

This unit suits contractors fitting 3/4in piping where automatic venting is required. It is not for systems that demand a larger connection size, a different body material or a higher pressure rating than 150 psi.

1/2in NPT expansion tank port

The female NPT connection accepts a standard expansion tank and the fixed inlet-to-outlet distance fits tight mechanical rooms. Headroom ends when the application exceeds the 150 psi limit or requires a connection size other than 3/4in.

Questions about this item

Does my system need a 1/2 in female NPT connection to attach the expansion tank?

Yes, the unit provides a 1/2 in female NPT port for the expansion tank connection.

Will the 3/4 in in-line body fit between my existing 3/4 in copper pipes?

The in-line brass body is sized for 3/4 in piping with a 3 3/4 in centre-to-centre port spacing.

How can I confirm the automatic float vent is releasing air after installation?

Watch the float vent during system fill; it should discharge air quietly and then seal once water reaches it.
