Hakko Air Pumps are high volume diaphragm pumps designed for a variety of low-pressure applications.
Koi pond aeration, large aquarium aeration and earth pond destratification are only a few of the many applications for Hakko pumps.
Hakko pumps are compact, affordable, energy-efficient and very, very quiet (less than 38 decibels!)!
Hakko units utilize linear- motor theorem to reduce power consumption during full operation. Units are extremely quite utilizing spectrum analysis technology in order to decrease any mechanical noise.
- No oil needed for lubrication making the Hakko easy to maintain.
- These are the best large air pumps available today.
- 36 month warranty through the manufacturer.
