HVAC Air Separators

Air separation is a common term when discussing HVAC Equipment, and can be accomplished in a variety of ways. For instance, with the Standard & High Velocity Air Dirt Separator it is removed as it passes through the coalescing media, the micro-bubbles are separated and rise through the vessel where they are vented. As the dirt flows into the separator, it is ensnared by the coalescing saddle rings, where it eventually works through the coalescing media to the bottom of the separator where it can be blown down either through a manual or automated ball valve. 

MG / MO - Magnetic Option 

American Wheatley magnetic option for air separation devices. Available on American Wheatley TAS, TASS, IAS, IASS, SRS, STAD, and HVAD air separation devices. 

The MG option includes a minimum of three diametrically charged magnetic assemblies inserted into the lower section of the air separation device.

These high-powered magnetic assemblies attract small ferrous particles and magnetite, preventing them from flowing into the pup and further into the system. The internal magnets can be easily removed, allowing the particles to be flushed from the system during periodic blowdown, without system disruption.  

The obvious function is to remove as much air and dirt from the system fluid so that it does not cause any adverse effects on system efficiency or its components, through continuous circulation.

The Wheatley STAD and HVAD air & dirt separators utilize serval physical actions to accomplish this. Micro - air bubbles pass through, over, around, above and below the many 304SS saddle rings contained in the coalescing basket. While trying to pass through the coalescing media, the mircro-bubbles cling to the myriad of twists sand turns required as they count their journey through the coalescing basket.

As these micro-bubbles collect, they join together and form larger air molecules which with then detach from the saddle rings and are expelled from the system through automatic float type air vent located at the top of the air * dirt separator.

As any system pollutants, or dirt, are circulated through the air * dirt separator coalescing basket, they too collide with the saddle rings and are separated from the ater and subsequently expelled through periodic blow-down through the blow-down port on the bottom of the separator, or removal and cleaning of the coalescing basket if so equipped.
