Deltec's 3070 external skimmer has an ETA ratio of around 60 to one, thus being able to produce 1500 liters of air per hour , using only 25W of power. The name TC describes the special double bubble chamber design that is patented and has the advantage of pressurizing the pumps for higher performance. This ensures that only non-foamed water passes through the pump and prevents reprocessing of water in the chamber. The new bubble plate design allows the height of the skimmers to be reduced compared to the current range so they can fit into a larger number of installations. The primary purpose of the bubble chamber is to prevent turbulence from the skimmer body and neck, as turbulence can pull debris back into the water column causing a reduction in efficiency. The air to water ratio is so high that there is an almost immediate reaction with the waste, therefore there is no requirement for the height of the reaction chambers (unlike low air to water ratio skimmers, which do). have), thus keeping the units very compact. Specifications: Total height measurement includes about 20mm for cup removal Exceeds the performance of AP1004 (2400 liters of air - 230 V) Base measurement: 375x375mm Measurement of the base with pipe: 470x382mm Overall height: 700mm Height under tube outlet: 264mm Air flow: From 2x1500 to 2x1600 l/h Power consumption: 2 x 29W-34W Water flow: 3600 l/h 160mm neck diameter Inlet pipe diameter: 32mm Outlet pipe diameter: 50mm Patented Bubble Chamber Twn Chamber Valid for tanks up to 4800 liters Remote skimmer bowl drain air silencers High water flow through the skimmer Self-cleaning system (optional, not included) Can be gravity or pump fed (supply pump not included)
