Commercial Air 1 - 38 Liter/min - 4 Outlets - 18 Watt
Convenient to operate without oil or much noise. Cylinders and pistons are made of excellent materials, making the air pump strong, durable. There is very little wear after long periods of operation.
Will meet many requirements of air pumps with air dividers from four to twenty-two outlets.
Widely used to provide oxygen in aquariums, fish farms & hydroponic systems. One year warranty.
I use this pump in a 5 gallon bucket to make compost tea. A little overkill, but I'd rather more dissolved oxygen instead of too little.
