Thrush AHF Series - Manual (Page 7)

3.1.1 Coalescing Medium
Each Aar-O-Vent model incorporates an all stainless steel coalescing medium often
referred to as the bundle. This coalescing medium eliminates virtually any dirt particles,
air bubbles and/or entrained air from the water by means of an air eliminator or blow
down valve. This patented design resists corrosion and can be easily cleaned.

3.1.2 Sight Glass (Optional)
One of the optional features offered with each Aar-O-Vent is sight glasses. Sight glasses
allow the user to periodically check the coalescing medium for signs of dirt build-up.
