Noisy pipes, valves, and other air-related noises are often accepted as the signs of a functioning system. Excessive pump noise, cavitation, and cascading in terminal units are considered normal. But air in system water can cause corrosion, reduced efficiency, poorly heated or inadequately cooled rooms, accelerated component wear and on-going complaints. There is a device that will keep your system free of air permanently. Less maintenance, quiet operation, fewer costs!. Unlike conventional air eliminators or air scoops, the Spirovent completely eliminates 100% of the free air, 100% of the entrained air, and up to 99.6% of the dissolved air in the system. Consisting of woven copper wire soldered to a copper tube, the patented Spirotube creates a low velocity area in the Spirovent that scrubs the bubbles from the water. The air bubbles rise and collect in the air chamber before they are vented from the system via an integral automatic valve. Air problems become a thing of the past.

• Maintenance free
• No venting required
• Vent head is designed to stay dry, dirt and leak resistant
• 1/2" male thread port for pressure testing or remote venting of unwanted gases
• Quiet operation
• Increased component life
• Reduced oxygen based corrosion and pump cavitation
• The automatic air vent is guaranteed not to leak and can only be closed by the installer for a pressure test
• The air chamber has been designed so that dirt cannot reach the valve
• Large capacity collection chamber reduces the need for frequent draining
• Drain valve for flushing out the dirt
• Brass vent head
• Non-ferrous float
• ViTon seal and o-ring
• Copper coalescing medium

Watts Water AS-MB100

Taco air scoop's 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. They also provide an economic way to integrate air elimination by the connection of either a plain steel or diaphragm expansion tank.

• 1-piece cast iron construction
• Never requires any servicing
• Engineered baffle separates air from water
• Each air scoop has a vent connection on top for the installation of a 1/8" Taco 400-3 or 416-1 Hy-Vent and 1/2" bottom tapping for a diaphragm expansion tank
• The 1-1/2 - 4" air scoops also have an additional top tapping for the connection of a plain steel expansion tank
• Water or water/glycol media
