Air Elimination & Control
The Air Elimination category includes all of the products used to remove entrapped air from hydronic heating, cooling and combination systems. Included in this category are Automatic Air Vents, Air Scoops, Vortex Air Separators®, large Tangential and In-Line Air Separators, Expansion Tanks and Buffer Tanks.
Air Separators
Taco Air Scoops® and Air Separators offer you a variety of ways to efficiently remove air from various HVAC systems over a wide range of operating pressures and flows.
900 Series Air Separators (Commercial)
The Taco 4900 Series Air Separators help you save money and prolong the life of system pumps, piping and components by removing air and dirt from the system to prevent:
- Reduced heat transfer
- Loss of efficiency
- Pipe corrosion
- Pump damage
- Increased energy consumption
- Irritating noise
The high efficiency Taco 4900 Series Air Separator uses patented PALL ring technology to clear the system of micro bubbles, sand, dirt and rust to save money, energy and component wear. PALL rings are used in the processing industry to mix gases with, or separate gases from, liquids. By applying PALL ring technology to hydronic air and dirt separation, the 4900 Series will:
Remove micro bubbles as small as 18 x 10 –6 meters from the system
- Remove air that has dissolved in the system water
- Remove air from places where an air vent can’t be installed
- Remove and separate solid particles from flow.
Series 4900-A models clean the system of free air and micro bubbles. Series 4900-AD models remove both air and dirt from the hydronic system. All models are built to Section VIII of the ASME code.
Air Vents
HVAC professionals have recognized Taco Automatic Air Vents as the industry standard for more than 30 years. Attached to the boiler or used through the system, Taco Vents automatically purge unwanted air from any hydronic installation, allowing the system to run more efficiently. Taco Automatic Air Vents include:
The Taco Automatic Coin Vent
Installed on water or steam radiators, the Taco Automatic Coin Vent is the ideal air purging device. The Coin Vent features special hygroscopic cellulose discs in the valve body that, when dry, allow air to be released from the system. When air is purged, the discs come into contact with system water, which causes them to swell, creating a positive shut-off. This continuous cycle prevents radiators from becoming air bound and speeds the process of filling the system. Vents also can be manually shut off using an internal ball check.
Taco Hy-Vents®
You already know Taco Hy-Vents® as the industry standard for dependable, long-life service. The high-capacity, float-style vent can be placed either on the boiler or at the high points throughout the system. With threaded connections–1/8”. 1/4”, 1/2” and 3/4” –and operating pressure ratings up to 250 psi, these brass-body, nickel-plated vents meet the system requirements of even your largest installations. Vents are easily serviceable, if needed, by simply unscrewing the vent cap. Taco Hy-Vents® are available in a variety of styles including the Slim-Line Hy-Vent and High Pressure Hy-Vent.
The Taco 409 Automatic Air Vent
The high-capacity design and 150-psi system operating pressure rating make this heavy-duty, brass Air Vent ideal for placement throughout commercial systems. Its conical shape significantly increases the clearance between the water level and internal mechanisms, reducing the potential that dirt floating on top of the water can foul the venting operation. Also features a convenient outlet connection for a 3/4” ID flex tube waste connection.
