AquaClear Powerhead as Air Pump

[platytudes]

many of the small airpump like the whispers utilize vibrator motors to operate the diaphram. there are other airpumps that don''t use this style diaphram. these are usually much quiter..but more costly

Do you happen to know what sorts of air pumps don't use vibrator motors? I have a friend who is always having to replace diaphrams - but he seriously overloads his gang valve and his hard water plugs the airstones fast, putting out a lot of resistance. I know he has been looking for an alternative to vibrator motors.

you can also look at linear pumps or pumps that use pistons opposed to diaphrams.
