Not really sure on Max distance Jokar? I have one and it's about 80 feet from mine, but as Cody says you can go quite a ways with them. Remember running air through a line really doesn't take much toll on a pump. It's pushing the air upwards from at a certain depth in the water is where your pump comes into play.
These Eco 7 pumps are good for about 10 foot like Cody says above around that 12 foot mark it will start to struggle some.
