The Pentair Aquatic Eco-Systems Whitewater® blowers are a very good value for aquariums, pet stores, bait systems and seafood holding systems. They are smaller, lighter and quieter than most blowers and very energy-efficient. They feature a "cupped" impeller for reduced noise. The specially designed motor is low in power consumption and excellent in performance. Blowers are 115V/60 Hz. One-year warranty. All blowers include air filter, filter connections, flexible outlet hose and 6' power cord.
