super strong my 1200 liters and its very good
Great compressor! What a surprise. Very powerful and quiet. I have a General Hydroponics (20L/min) which is the quitest, almost silent. This one is a little louder, but with much more air. Became my choice. I turn the power down half way (54L/min version) and is still bigger volume with a little humming noise (low). Downside is that I can´t find the repair kit and these diaphagms wear out. Hope they last.
