Very reliable, economical, low noise, oil free air pump. It is piston operated instead of a membrane. High air pressure to a max depth of 2 - 2,5 metres (depending on model). Attention: the maximum head pressure can exceed 2 metres due to a long distance to the manifold, smaller diameter of the hose used and so on, regardless of the pond depth! When these pumps exceed more than 2 metres of head pressure there will be a great chance of failure. Advice: Recommended to fit a pressure gauge on the outlet to check outgoing pressure. 1 year warranty.
