Aquael ULTRAMAX are high-tech external cartridge filters with patented solutions. They guarantee exceptional ease of use and ensure perfect water purity and optimal parameters in all aquariums, even the most demanding. The pre-filter reduces the frequency of cartridge cleaning, and its placement in the unit's housing allows for replacement without disassembling the filter head! Advantages: – Unprecedented efficiency – ULTRAMAX filters are characterized by a very high water flow rate (max. 1000 to 2000 l/h), enabling them to operate efficiently even in very large aquariums (up to 700 l). Furthermore, they contain a significant number of filter cartridges housed in convenient and ergonomic baskets with a capacity of 1.9 l each (the number of baskets varies from 3 to 5 depending on the model). This ensures 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 – a new feature on the market. The lid of each ULTRAMAX filter has a large integrated sponge pre-filter (with a capacity of approximately 0.6 liters). Its purpose is to capture larger mechanical impurities before they reach the inside of the filter. This effectively protects the unit from clogging and minimizes the frequency of cleaning. Simply rinse the pre-filter sponge regularly under tap water – this procedure takes only a few seconds and does not require unplugging 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 over 30 years of experience from AQUAEL's manufacturers, combined with the ceramic rotor shaft, guarantees inaudible and virtually noiseless operation. Thanks to this, the filter can operate silently in any room, even the bedroom! – Extremely low power consumption – AQUAEL cares about the environment and its customers' wallets. Therefore, the innovative ULTRAMAX filters are characterized by very low energy consumption, resulting in lower bills. The ULTRAMAX 2000 has a power consumption of only 24 W! – Safe operation – 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 large filter media capacity – ideal conditions for the development of nitrifying bacteria – Automatic filter priming mechanism on first start-up – Integrated shut-off valves. Technical specifications: – Power: 15W – Flow rate: 1500 l/h – Dimensions: 27x29x39.5cm – Pipe diameter: 16/22mm – Filter capacity: 13.5 liters – Adjustable flow rate
