Hagen Fluval Air Pump Q 0.5
Powerful yet extremely quiet, the Fluval Q1 Air Pump produces consistent air flow thanks to an advanced swing-arm and diaphragm design.
A thick double-wall outer casing, integrated pump well and noise-suppressing baffle chamber make Fluval one of the quietest air pumps to date.
The Q0.5 is quality constructed and will provide lasting and reliable performance for aquariums up to 50 U.S. gal. Ultra Quiet.
