Aquael ULTRAMAX are high-tech external cartridge filters with patented solutions. They guarantee extraordinary ergonomics of use, they will ensure perfect purity of the water and its parameters in all aquariums, even the most demanding. The pre-filter used limits the frequency of cartridge cleaning and its insertion in the hood of the device allows its replacement without disassembling the filter head! Advantages: – Unprecedented efficiency – ULTRAMAX filters are characterized by a very fast water flow rate (max. from 1000 to 2000 l / h), which allows them to work efficiently even in very large aquariums (up to 700 l). In addition, they contain a significant quantity of filter cartridges placed in comfortable and ergonomic baskets with a capacity of 1.9 l each (the number of baskets varies depending on the model from 3 to 5). Thanks to this, they guarantee extremely efficient filtration, both mechanical and biological. They consist of a set of filter media carefully selected to meet the needs of a typical aquarium. – Integrated pre-filter – this is a novelty on the market. The lid of each ULTRAMAX filter has a large sponge pre-filter (with a capacity of approximately 0.6 liters). Its task is to capture thicker mechanical impurities before they reach the inside of the filter. Thanks to this, it effectively protects the device from clogging and reduces the cleaning frequency to a minimum. Therefore, it is sufficient to regularly rinse the pre-filter sponge in tap water – this procedure takes only a few seconds and does not require disconnecting the filter from the power supply or removing it from the aquarium cabinet. – Perfectly silent operation – the well-thought-out design of the filter pump rotor and its chamber, based on more than 30 years of experience of AQUAEL manufacturers, in combination with the ceramic rotor axis, guarantees inaudible and virtually noiseless operation. Thanks to this, the filter can operate silently in any room, even in the bedroom! – Extremely low power consumption – AQUAEL takes care of the environment and its customers' wallets. Therefore, the innovative ULTRAMAX filters are characterized by very low energy consumption, which translates into lower bills. The ULTRAMAX 2000 has a power of only 24 W! – Safe to use – The water inlets and outlets in the ULTRAMAX filters are equipped with extremely robust double ball valves. This allows for quick and easy disconnection of the filter hoses during cleaning and prevents even small water leaks! – The ULTRAMAX line includes three models (ULTRAMAX 1000, 1500, 2000) with capacities ranging from 1000 to 2000 l / h. very high capacity of the filtration media – ideal conditions for the development of nitrifying bacteria – Automatic filter priming mechanism on first start-up – Integrated shut-off valves Technical characteristics: – Power: 15w – Flow rate: 1500 l/h – Dimensions: 27x29x39.5cm – Pipe diameter: 16/22mm – Filter capacity: 13.5 liters – Adjustable flow rate
