Aquasphere Isaver-X1100 variable frequency drive for pool pumps

The AstralPool 75947 variable frequency drive is designed to convert a fixed-speed pool pump into a variable-speed pump, adapting the flow rate to the actual filtration requirements at any given time. By reducing the rotational speed during much of the operating time, it can achieve significant energy savings compared with traditional operation at a constant maximum speed, while also providing much quieter operation.

This equipment is installed between the electrical panel and the single-phase pump (up to approximately 1.1 kW / 1.5 HP) and allows the motor speed to be adjusted across a wide operating range (typically between 1,200 and 2,900 rpm, depending on the configuration). It features an integrated programmer/timer for defining different operating time slots and flow rates, thereby optimizing filtration cycles and adapting them to the pool's usage schedule.

The variable frequency drive is protected with an IP65 ingress protection rating, making it suitable for installation in the technical room or pool equipment shed. By operating at a lower speed for much of the time, it reduces mechanical pump wear, improves filtration quality (water passes more slowly through the filter), and extends the equipment's service life. It is an ideal solution both for upgrading existing installations with conventional pumps and for new pools where energy efficiency, acoustic comfort, and lower operating costs are desired.
