{"product_id":"wright-austin-type-st-cast-iron-separator-integral-trap","title":"Wright-Austin Type ST Cast-Iron Separator with Integral Float Trap, 1-1\/2 and 2-1\/2 in. NPT","description":"\u003cp\u003eWright-Austin has been building these since before most of the compressed air industry existed, and the Type ST is the version that does not need a separate trap hung off the bottom. Separator and float trap share one cast-iron body. Air spins, liquid drops out, the stainless float opens the valve and ejects condensate without losing line pressure. There are no moving parts in the separating section at all, which is why these units outlast the compressors they are fitted to.\u003c\/p\u003e\n\u003ch3\u003eKey specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBody: cast iron, ASTM A-278\u003c\/li\u003e\n\u003cli\u003eWorking pressure and temperature: 250 PSI at 450 F\u003c\/li\u003e\n\u003cli\u003eEfficiency: removes 99 percent of liquid and solid entrainment 10 micron and larger\u003c\/li\u003e\n\u003cli\u003eTrap internals: non-magnetic 18-8 stainless valve and seat, hollow stainless float\u003c\/li\u003e\n\u003cli\u003eStandard orifice: 1\/8 in. with Viton soft seat\u003c\/li\u003e\n\u003cli\u003eDrain connection: 3\/4 in.

A 450 F rating puts the Type ST straight on a compressor discharge where aluminum and zinc separators have no business being, and it handles saturated steam service as readily as compressed air. The trade is obvious the first time you lift one onto a pipe stand. Budget for proper support: this is not a unit you hang off threaded pipe and hope.\u003c\/p\u003e\n\u003ch3\u003eCode status\u003c\/h3\u003e\n\u003cp\u003eNo ASME code stamp and no CRN is available on the cast-iron ST. If your jurisdiction or your insurer requires a stamped vessel at this point in the system, this is not the separator for that location, and it is better to know now than at inspection.\u003c\/p\u003e\n\u003ch3\u003eLineage\u003c\/h3\u003e\n\u003cp\u003eThe line has been sold as Wright-Austin, then under Eaton Filtration as the Type T and ST, and most recently through Hamlet and Garneau. Catalog numbers never changed. A 1.5STBN ordered today is the same casting as a 1.5STBN ordered thirty years ago, which is useful when you are matching an existing installation rather than designing a new one.\u003c\/p\u003e\n\u003ch3\u003ePricing note\u003c\/h3\u003e\n\u003cp\u003eBoth sizes are current closeout stock.
