The propeller driven Swimstream swimming machine is capable of moving over 1.2 million liters of water per hour. That is over 10 times the capacity of a conventional jetstream pump system and plenty more than 'turbine'-like systems.
Swimstream's counter current is impressively wide and even. Behind the grills there is a special design to guarantee a water stream as laminar as possible.
The water's speed is adjustable from inside the pool. In addition to an incredibly powerful swim current, one could also swim against a slow moving, but still large body of moving water. An extremely comfortable swimming experience and excellent for both exercise and pleasure.
