turbo-venturiŽ injector these inexpensive venturis are ideal for small protein skimmers and koi ponds made of ozone-resistant abs plastic both models are fnpt inlet and mnpt outlet each 10 venturi low cost v12 our venturi fittings were engineered to entrain the greatest amount of air with the least resistance to water pressure when pumping water these may be used to draw in liquids or gases including low-strength ozone made of pvc with standard slip connections venturi 4734 is fiber-reinforced plastic and has female slip ends made in usa 4738 3/4 in x 1 out each 10 4732 11/2 in and out 4738 venturi tee pvc 8.60 7.74 both are female 4732 venturi tee pvc 11.02 9.91 slip w 3/4 air inlet 4734 venturi plastic 13.88 12.52 3/16 male barb aeration injectors/eductors/tech talk v12 v34 1/2 3/4 npt npt 3­30 gpm 5­40 gpm 20.30 22.25 18.88 20.69 mixing eductors it s easy to multiply the mixing force of pumped water this nozzle requires as little as 7.5 gpm to draw in five times more molded of glass-filled polypropylene with smooth surfaces recommended flowrates shown are for between 10 and 50 psi oal gpm each 6 24 air in 4734 ed2 ed1 ed3 3/8 mnpt 3/4 mnpt 11/2 mnpt 4.5 4.5 10 7­17 31.30 13­30 24.70 33­75 59.15 29.67 27.54 23.41 21.74 56.13 52.05 3/4 male slip 4738 water and air out water in ed3 venturi injectors by mazzeiŽ mazzeiŽ venturis offer an efficient and reliable way to inject virtually any liquid or gas into water widely used for the injection of air oxygen and ozone when installed properly injectors can transfer ozone into water with efficiencies as high as 99 percent these venturi injectors are made of pvdf kynarŽ and are ozone compatible all include a 1/4 barbed ozone-safe check valve maximum operating pressure is 400 psi made in usa v384 tech talk 63 venturis a well-designed venturi working in shallow water to aspirate air may cause as little as 15 percent additional head pressure and as little as 10 percent reduction in volume pumped therefore a venturi can be a very economical device to operate especially when it completely eliminates another piece of equipment such as a chemical metering pump an air pump or an ozone unit s air pump they are particularly useful when injecting chemicals and gases that are aggressive in nature and would require special materials for the pumping device as a venturi draws air into a depth of about 2 feet there will be increased water pressure resistance and a reduction in volume pumped when used with low-pressure pumps the increase in head causes such a large reduction in volume that the venturi application becomes impractical when sucking air the deeper the depth the greater the pressure needed when installed properly venturi injectors can transfer ozone into water with efficiencies as high as 99 percent venturis have no moving parts and provide trouble-free operation inlet/outlet mnpt 1/2 mnpt v384 3/4 barb v584 v978 1 mnpt v1584 11/2 mnpt v514 2 mnpt flow thru injector @15 psi in/5 psi out air suction @15 psi in/5 psi out each 4 1 gpm 3.3 gpm 7.4 gpm 31 gpm 60 gpm <1 cfh 4 cfh 13 cfh 90 cfh 160 cfh 76 54 138 173 396 69 49 124 156 373 has been around for 12 years it has seen dot-com booms busts and new booms we continually improve our site to make your shopping easier order by phone 877-347-4788 tech support 407-598-1401 aquaticeco.com 62 order online aquaticeco.com
