{"product_id":"dramm-pcas-pressure-compensated-emitter","title":"Dramm - PCAS Pressure Compensated Emitter","description":"\u003ch2\u003ePCAS Pressure Compensated Emitter\u003c\/h2\u003e\u003cp\u003ePCAS emitters hold their rated flow across a wide pressure band, so the first pot on a bench and the last one on the run get the same volume. Dramm rates them from 15 to 50 psi at the dripper and recommends keeping at least 25 psi at the manifold so the last dripper still sees the minimum after line loss. The compensating element is a chemical tolerant silicone diaphragm, and Dramm has deliberately made the body larger than its previous emitter so the labyrinth is wider and passes debris instead of trapping it.\u003c\/p\u003e\u003cp\u003eTwo things to choose. Flow rate is the horticultural decision: 2 lph (1\/2 gph), 4 lph (1 gph), 8 lph (2 gph) or 12 lph (3 gph), delivered at that rate anywhere in the 15 to 50 psi window. Outlet is the plumbing decision and is not cosmetic. A barbed outlet pushes straight onto 0.191 in OD leader tube, and it is what the 2 lph comes as; PressFit is a barrel outlet, which is how the 8 lph and 12 lph come, and it reaches Dramm 192 tubing through the MAN1 barrel-to-barb adaptor. The 4 lph is the one flow offered both ways. Read the insert colour with the outlet style, not on its own: black is 2 lph barbed, green is 4 lph, red is 8 lph and black again is 12 lph PressFit, so colour alone does not identify a flow rate already in the house.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eFlow rate by option\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e2 lph (1\/2 gph), 4 lph (1 gph), 8 lph (2 gph) or 12 lph (3 gph)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOperating pressure\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e15 to 50 psi at the dripper\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eRecommended manifold pressure\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eAt least 25 psi, so the last dripper still sees the minimum after line loss\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eOutlet by option\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eBarbed on the 2 lph and one 4 lph;
