Thanks! I checked them out. That 1/8 HP looks interesting and has a good price. Question is will 0.5 cfm @ 50 PSI operate a diffuser in 4 feet of water and keep a big enough hole through the ice?
The typical 9" membrane diffusers require between .5 and 4-5 cfm and .5-5 psi (at the membrane) to operate properly. Under .5 cfm airflow or under .5 psi at the membrane will not open all diffuser pores and over the max rates will "Flex" the diffuser for cleaning the slits...extended over capacities will blow out the diffuser membranes.
