POND ONE O2Plus Air Blower 4000 (no stones and no tubing included)

02 Plus Air Blowers from Pond One are specifically designed for outdoor use and are resistant to the perils that extreme weather can throw at them. Fitted with a 10m cable, installation is made simple in comparison to other models around. 

02 Plus 4000 air machines are extremely powerful units. With outputs of 35, 70, and 110 litres per minute these are suitable for seriously large ponds or filters to stimulate aerobic activity or simply to add more oxygen to multiple points around the pond. With the design based on the Aqua One indoor units, quietness is a given. Outlet size is 1/2 inch. 

Each unit comes with a 10-gang splitter allowing multiple air stones to be run simultaneously. The diaphragms of these pumps are Japanese silicone rubber cartridges that offer excellent reliability and life expectancy.
