It shares the EVair 400 pump and "Beer Bottle" curved body with the K1-100, scaled up to a larger body diameter for the higher bioload range. Bioload capacity: 80 gallons (heavy), 100 gallons (medium), 140 gallons (light) Pump: EVair 400 pinwheel pump, 8 watts, ~400 LPH air draw, ~100 GPH water draw Dimensions: 5in body, 7.3in x 5.6in footprint, 19in total height Cup drain: 8mm ID / 12mm OD Recommended sump water height: 6-8 inches Warranty: 1-year on pump and skimmer body Install: in-sump only Same pump platform as the K1-100 — the wider 5in body is what unlocks the higher bioload rating by giving foam more room to stabilize before reaching the cup.Compatible replacement parts: EVair 400 pump kits for the K1-130.
