The Whisper Air Pump name has always been synonymous with reliability and quietness and since 1976 when the original Whisper Air Pump was manufactured over 15 million units have been sold world-wide and many of the original units are still running today! However technology has now moved on and 1999 saw the launch of the all-new Tetratec Whisper Airpump which is quieter, more powerful and even more reliable!

These airpumps have been redesigned from the drawing board up, to produce whisper-quiet compact units with startling performance. Using already tried and tested Whisper know-how the units have been designed using up to the minute electromagnetic technology and components which when combined produce units which provide amazing aeration performance even in the deepest of aquariums. By deliberately producing prototype over-engineered units and then scaling them down, the new Tetratec Whisper Air Pumps actually work less hard for a given performance level increasing their reliability and lifetime but more importantly making them exceptionally quiet.

Even the flow control on the 3 largest units has been designed with increasing reliability and performance. Utilising an air-bleed system instead of the usual air-restriction method, results in a decrease in back-pressure on the diaphragms increasing their life and the life of the pump. Combining all this with a vibration-absorbing rubber base and a sound deadening dense plastic casing really has produced an air pump which is truly Whisper quiet! In fact independent tests carried out by Virginia Polytechnic Institute and State University in Blacksburg, Virginia USA have shown that even the largest models produce a noise level of only 28dBA with the smaller units producing a mere 18.7 dBA - Whisper quiet indeed! As ever Tetra have taken the fishkeepers requirements for aquarium air and have produced a truly amazing air pump which is Powerful, Reliable and Whisper Quiet! The Tetratec Whisper Airpumps are available in the following models;
