Air Flow : 40 Litre per minute. Power Consumption : 27 watt Noise Level : 32 dB The new RII series air pumps have undergone over five years of rigorous testing by FujiMAC research and development staff. These pumps are designed to withstand the elements with a durable cast aluminum housing employing the latest paint finishes. Final assembly is done in a highly controlled environment by skilled Japanese staff with continuous oversight and numerous quality control checks. Each individual pump is then tested and performance measured prior to packaging. Extreme duty testing FujiMAC employs many testing techniques to ensure our pumps will stand up to such harsh environments as Southeast Asia humidity and the hot Texas sun. Shown here are pumps being run continuously for years in a uncontrolled outdoor environment, and also paint adhesion testing every day to ensure the baked on automotive quality finish will stand the test of time. Engineering design breakthroughs make FujiMAC the best choice for energy conservation and economical operation. FujiMAC has the lowest operating cost of any wastewater air pump. Best in class noise level is achieved through our proprietary sound reduction technologies, including a unique noise barrier aluminum housing and anti vibration rubber technology.
