What is an AC pool filter and what is it used for?

An AC pool filter is the combination of pump + hydraulic filtration to move water from the pool through the filter using AC from the grid or an inverter. It is available in 230 V single-phase and three-phase 230/400 V, which allows for continuous operation, integration with standard automation systems, and, if desired, control via VFD. It is the natural choice when a stable power supply is available and operational simplicity is desired.

Advantages and limitations

  • Simplicity and immediacy: direct connection to 230 V (single/three-phase) with standard protections (MCB/RCBO, thermal relay).
  • Continuity: ideal for maintaining complete filtration cycles regardless of solar irradiation.
  • Advanced control: optional use of VFD to modulate flow/pressure, reduce consumption, and smooth startups.
  • Limitations: higher energy cost than a solar solution; requires planning for consumption in the electrical contract or inverter.

Common applications

  • Residential and community pools operating several hours a day throughout the season.
  • Installations requiring 24/7 service or extended hours.
  • Systems with chlorination, dosing, or home automation controls in the AC panel.

How to choose your AC pool filter

  • Pool volume and turnovers/day: Target flow rate (m³/h) ≈ volume / effective operating hours.
  • TDH (m): sum of static head and losses in pipes, valves, and filter. Choose the model based on its flow–head curve with margin.
  • Power supply:
    • 230 V single-phase: for residential and moderate power requirements.
    • Three-phase 230/400 V: for larger pools or long lines; lower current per phase and easy integration with VFD.
  • Hydraulic compatibility: pipe diameter, filter losses, type of connections, and water quality (prefilter/skimmer recommended).

Indicative specifications

Typical flow rate 12–36 m³/h (depending on pool and filter size)
Manometric head 9–27 m (includes filtration circuit losses)
Power supply 230 V single-phase | Three-phase 230/400 V (50/60 Hz)
Control Timer / Press-control / VFD (optional)
Protections Dry run (probes), thermal, surge, non-return
Catalogue status AC range (single/three-phase) in progressive expansion

Best practices

  • Size the flow rate by turnovers and schedule enough hours to maintain water quality.
  • Check the actual TDH: filter and valve losses add head; clean prefilters to maintain performance.
  • Install protections: MCB/RCBO, thermal relay, dry run and surge protection.
  • With VFD, adjust ramps and target pressure to reduce consumption and water hammer.
