Taco 4903A-250, 3" Flanged Air Separator, 250 PSI

This Taco 4900 Series Commercial Air Separator, Model 4903A, is a reliable and durable product that is specifically designed for use in hydronic systems. With a 3" flanged connection and a maximum pressure rating of 250 psi, this air separator is capable of removing air from the system with ease. The product works by using a tangential flow pattern to separate the air from the water, which is then expelled through an automatic vent valve. This ensures that the system runs smoothly and efficiently, without any issues caused by trapped air. The Taco 4900 Series Commercial Air Separator is an essential component for any hydronic system that requires optimal performance and reliability.

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.
