air diffusers although the perfect diffuser one that emits extremely fine bubbles performs with no loss in pressure weighs enough to hold itself down and never clogs hasn t been created yet our high-quality sweetwater® diffusers are as close to perfect as diffuser technology has come with an air resistance of less than .25 psi sweetwater® glass-bonded diffusers are compatible with economical low-pressure blowers sweetwater ® diffusers are the highest quality ceramic-type air diffusers on the market today they re machined from a solid block of glass-bonded silica because dust and dirt particles up to 30 microns in size will pass right through these diffusers there s no need for expensive air filters they produce a uniform medium/fine bubble and are very resistant to clogging and when cleaning does become necessary because of a buildup of calcium precipitate or bacteria an acid bath restores them to like-new performance two-year warranty made in usa sweetwater® the best with their round grain pore structure low resistance to air flow uniform porosity and resistance to clogging sweetwater ® diffusers are clearly the best diffusers available for general aquaculture aeration smaller pores don t necessarily produce smaller bubbles sweetwater® diffusers are engineered to produce the smallest bubble possible within the constraints of a reasonable service life in most softwater applications they won t need to be cleaned for more than a year note that water ph in excess of 9.0 will shorten the diffuser life self-weighting when used with typical tubing lengths beware of imitations sweetwater® diffusers are the original 2,000°f glass-bonded silica diffusers introduced by aes in 1984 you may come across other diffusers that copy our sizes descriptions and even our photos but it takes more than flattering imitation to compete with the best look for the name and the two-year warranty compare closely buy one sweetwater® brand and one brand x and compare for diffusion uniformity and bubble size the most important qualities of a diffuser also compare pressure clogging rate and cleaning ability many of our customers are still using the same sweetwater® diffusers they bought over 10 years ago aeration medium pore diffusers we follow a policy of continuous improvement and reserve the right to alter published data as2 als3 medium pore diffuser specifications body 2,000°f glass-bonded silica fitting abs as1 as2 linear polyethylene or special order maximum pore size .140 microns 0055 inches bubble size 1-3 mm 04 15 inches nominal particle retention 50 microns service life at ph below 8.0 .unlimited flexural strength .2,500 psi length width suggested cfm 1 lpm .035 cfm 1 cfm 28.3 lpm 1 inch 2.54 cm this is the pounds of fish supported see tech talk 84 air supply connection actual wt in cm in cm as1 as2 as3 als3 as4 as5s as5l als5 as8s as8l als8 alr8 as15s as15l alr15 as23s as23l alr23 as30s as30l alr30 asw88s asw88l 1.5 1.5 2.0 2.0 1.5 3.0 3.0 3.0 3.0 3.0 3.0 3.0 6.0 6.0 6.0 9.0 9.0 9.0 12.0 12.0 12.0 3.0 3.0 4 4 5 5 4 8 8 8 8 8 8 8 15 15 15 23 23 23 30 30 30 8 8 .50 .75 1.0 1.0 1.5 1.0 1.0 1.0 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 1.5 3.0 3.0 1.3 2 2.5 2.5 4 2.5 2.5 2.5 4 4 4 4 4 4 4 4 4 4 4 4 4 8 8 .05 .10 .20 .20 .25 .30 .30 .30 .35 .35 .35 .35 .50 .50 .50 .75 .75 .75 1.00 1.00 1.00 .70 .70 1.5 3 5 5 7 8 8 8 10 10 10 10 14 14 14 20 20 20 27 27 27 19 19 3/16 o.d 4 mm abs 3/16 o.d 4 mm abs 3/16 o.d 4 mm pe 1/4 npt pe 3/16 o.d 4 mm pe 3/16 o.d 4 mm pe 1/4 o.d 6 mm pe 1/4 npt pe 3/16 o.d 4 mm pe 1/4 o.d 6 mm pe 1/4 npt pe 1/2 npt pe 1/4 o.d 6 mm pe 3/8 o.d 9 mm pe 1/2 npt pe 1/4 o.d 6 mm pe 3/8 o.d 9 mm pe 1/2 npt pe 1/4 o.d 6 mm pe 3/8 o.d 9 mm pe 1/2 npt pe 1/4 o.d 6 mm pe 3/8 o.d 6 mm pe .03 lb .06 lb .10 lb .10 lb .21 lb .16 lb .16 lb .16 lb .39 lb .39 lb .39 lb .39 lb .75 lb .75 lb .75 lb 1.35 lbs 1.35 lbs 1.35 lbs 1.50 lbs 1.50 lbs 1.50 lbs .70 lb .70 lb 1.35 1.97 2.93 3.68 3.49 3.85 3.85 4.44 5.45 5.45 6.02 6.43 9.17 9.17 11.07 13.08 13.08 15.68 15.68 15.68 18.54 18.58 18.58 1.13/20 1.69/20 2.68/20 3.41/20 3.24/20 3.47/20 3.47/20 4.12/20 5.12/10 5.12/10 5.64/10 5.99/10 8.79/20 8.79/20 10.44/10 12.38/10 12.38/10 14.79/10 14.79/10 14.79/10 16.83/10 17.25/10 17.25/10 .95/100 1.40/100 2.27/100 2.88/100 2.73/100 2.97/100 2.97/100 3.49/100 4.65/50 4.65/50 5.26/50 5.74/50 7.84/50 7.84/50 9.52/50 11.24/25 11.24/25 14.16/25 14.16/25 14.16/25 14.93/25 16.75/25 16.75/25 dimensions of length and width are ±1/8 3 mm fitting is in center of 3 x 3 dimension the suggested cfm shown above is typical for aquaculture higher cfm amounts will create larger bubbles nonstandard fittings are available on request pe is high density linear polyethylene abs is green plastic order online aquaticeco.com order by phone 877-347-4788 tech support 407-598-1401 53
