Taco 4903AHT-125, Air Separator, 3" THRD, 125 PSI

This Taco 4900 Series Commercial Air Separator, Model 4903AHT, is a high velocity air separator designed for use in hydronic systems. It has a 3" threaded connection and can handle pressures up to 125 psi. The air separator works by removing air and other gases from the circulating water in the system, which helps to improve efficiency and prevent damage to components. As water flows through the separator, it is forced to change direction, causing any entrained air or gas bubbles to rise to the top of the unit where they can be vented out of the system. The Taco 4900 Series Commercial Air Separator is a reliable and effective option for maintaining optimal performance in hydronic heating and cooling systems.

4900 Series Overview

Taco 4900 Series Commercial Air & Dirt Separators efficiently remove air, dirt, and other contaminants from system components, enhancing efficiency and longevity. They use patented PALL ring technology to eliminate micro-bubbles and debris, while an optional magnet collects iron oxide and magnetite.

These separators also feature a vent mechanism for releasing merged micro-bubbles and a blowdown valve to dispose of dirt. The magnet, easily activated by a handle, simplifies maintenance and magnetite removal. They are suitable for systems with variable speed and constant flow.

Taco 4900 Series separators are constructed and tested to ASME Section VIII, Div. 1 standards. Their design is guided by computerized selection, tailored for each application. All manufacturing occurs in-house, ensuring quality. Independent third-party tests validate performance.
