The OASE AquaSkim 40 keeps the water surface of up to 40 m² clean and is an ideal addition to the AquaMax Eco Premium models 8000-16000 and Twin 20/30000. The skimmer basket has a diameter of 170 mm. It can be easily adjusted to the pond depth using the two-part telescopic tube, which is infinitely adjustable in height from 300 to 800 mm. The skimmer compensates for water level differences of up to 120 mm. The filter basket volume is 1.4 litres. The skimmer allows dirt particles up to 10 mm in size to pass through. Thanks to the 350 mm base, the AquaSkim 40 can be fixed to the pond floor with stones for extra stability. The small pipe diameter of 80 mm also ensures less air content and thus prevents the skimmer from floating, which has a connection with a universal stepped hose nozzle from ¾" to 1½". The guarantee is 3 years + 2-year requirement guarantee.
