Watts 0858536 Air Scoop
The Watts 0858536, also known as the AS-1 1/4 air scoop, is a fundamental component for professional hydronic heating system maintenance and installation. Engineered with a rugged cast iron body, this air separator is designed to efficiently remove air from the water stream, preventing the common service calls associated with noisy pipes and uneven heat distribution. Operating at a maximum pressure of 125 psi and capable of handling a maximum temperature of 275°F, it provides a heavy-duty solution for both residential and commercial HVAC hydronic applications. The unit features standard 1-1/4 inch FNPT connections, satisfying the flow requirements of most mid-sized boiler loops. By utilizing a physical internal baffle to create a low-velocity zone, this scoop forces entrained air bubbles to rise toward the 1/8-inch female threaded top tapping, typically used for a float vent, while the 1/2-inch bottom tapping accommodates a hydronic expansion tank connection. Integrating this Watts air scoop ensures a quiet, air-free system and protects downstream components from oxidative corrosion.
Key Benefits- Engineered Air Separation: Heavy-duty internal baffle design ensures efficient separation of air from system water to eliminate air-bound radiators and pump cavitation.
- Durable Construction: Built with a heavy cast iron frame to withstand the thermal stresses of high-temperature boiler feed lines.
- Versatile Integration: Includes dedicated tappings for a 1/8" air vent and a 1/2" expansion tank, simplifying the mechanical room layout.
- Optimized Flow: The 1-1/4" FNPT x FNPT connection allows for seamless installation in standard horizontal piping runs.
Where should the air scoop be installed for maximum efficiency?
For peak performance, install the scoop in a horizontal line at least 18 inches downstream from the nearest elbow or fitting. This allows the water flow to stabilize so air bubbles can rise and be captured by the internal baffle.
What size expansion tank can I use with the Watts 0858536?
The 1/2-inch bottom tapping is a standard size for most residential and light commercial expansion tanks. Always verify your system's total water volume to ensure the tank size is sufficient for the expansion rate.
Does this unit require regular maintenance?
While the cast iron body is virtually maintenance-free, the air vent installed in the top tapping should be inspected periodically to ensure it is not clogged by system debris or scale.
