save over 10 percent we offer these complete blower packages specifically designed for aquarium stores fish rooms hatcheries and laboratories all that is needed is a few hours of labor pvc pipe cement pipe cutter and 3/8 or 1/2 reversible drill they can be used to provide air to sponge filters air diffusers undergravel filters and even protein skimmers our packages use only aquaculture-duty sweetwater® regenerative blowers for the utmost in reliability the packages include 500 of 3/16 aquarium tubing tp30 and a thread tap and drill bit for mounting valves right where you want them a technical guide provides detailed instructions on how to design and build your air system the nickelplated valves included are far superior to plastic valves air diffusers are sweetwater ® brand as1 that are easily cleaned to restore like new performance all are 115v 50/60 hz add 230 after the part number for 230v made in usa blower packages for fish rooms by sweetwater® each blower package includes the following · sweetwater®regenerativeblower · flexibleoutletpipe · airbleedvalveassembly · nickelplatedvalves · teflon®sealant · plumbingtechguide number of as1 air diffusers 20 water depth number of valves/diffusers included aeration · inletmufflerassembly · powercord8 · airdiffusers · threadtapanddrillbit · 500 ofairlinetubing sweetwater blower packages/tech talk flex outlet size amps 115v ship wt s11k s21k s31k 100 380 560 50/50 100/100 150/150 1 1 11/2 2.0 3.8 5.6 30 lbs 727 34 lbs 860 40 lbs 1,042 s21k tech talk 2 incorrect pipe sizing all too often causes unsatisfactory performance friction is the culprit as the volume of air passing through the piping increases the pressure required to deliver the air also increases due to friction think of it as wind resistance since most aquaculture type aeration systems utilize low-pressure blowers it is critical that nonrestrictive piping be used pressure loss in air systems can be measured in inches of water h2o the resistance to airflow caused by friction will decrease both the pressure to the air outlet typically an air diffuser and the volume of air delivered when designing the air system it is important to add together all of the following the maximum water depth to which the air is driven the resistance in the air piping system and the resistance caused by the air diffuser our simplified chart can be used as a guide in determining the pressure loss caused by the piping the blower pressure and air diffuser resistances are published in this catalog if you are confused don t worry call an aes technician at 407-598-1401 for help example 4 cfm need to be delivered a distance of 200 feet from a rotary lobe blower the average line pressure is 3 psi there are no odd twists or elbows that need to be considered the minimum diameter of plastic pipe will be 3/4 causing 7.4 h2o resistance or pressure loss the smaller 1/2 pipe would cause 24.6 of loss which would probably be unacceptable a 1 pipe costing little more than the 3/4 might be an even better choice if there is the possibility of using more air in the future pipe sizing air calculations based on average pressure of 3 psi average air temperature of 90ºf and an air kinematic viscosity of 1.7 x 10-4ft2/sec under this temperature and pressure the scfm standard cubic feet per minute volume is 13 percent greater than actual order online aquaticeco.com order by phone 877-347-4788 tech support 407-598-1401 51
