New improved version of the popular Tornado protein skimmer. No more pressure loss on the inlet due to the absence of a venturi. Water goes straight into the filter. Air is blown into the 4mm air inlet through a supplied flowmeter to ensure a continuous flow of 0,5 l/m (30 l/h). This pressure ensures the separation of the produced foam through the foam outlet pipe. The protein skimmer is a combination of three different filter systems. The filter operates biological, mechanical and chemical.
