Why BWT MACH?

Innovation that changes maintenance

At the core of MACH is a patented rotary pulse back­wash system, further devel­oped by BWT to outper­form conven­tional filtra­tion.

  • Acti­vated with a simple 90° turn
  • Fully auto­matic stop when released
  • Complete cleaning in a few seconds
  • No disman­tling, no tools, no inter­rup­tion

→ Fastest and simplest main­te­nance in its class

2-phase back­wash for supe­rior cleaning

Unlike stan­dard systems, MACH uses a two-stage cleaning process:

  1. Coarse particle flushing
  2. Deep pore cleaning of the filter element

This ensures:

  • Improved cleaning of the filter surface
  • More effec­tive removal of fine parti­cles
  • Consis­tently high filtra­tion perfor­mance

→ Deeper cleaning. More reli­able results.

BWT MACH HWS – Domestic Water Station

Lower main­te­nance. Lower costs.

  • No cartridge replace­ment required
  • Back­wash recom­mended every 6 months
  • Filter element lifespan up to 5 years
  • Reduced need for service visits

→ Mini­mized OPEX and predictable life­cycle costs

Opti­mized water and resource effi­ciency

  • Reduced water consump­tion during back­wash
  • Long-lasting stain­less steel filter element
  • Fewer plastic compo­nents
  • 100% recy­cled pack­aging mate­rials

→ More sustain­able oper­a­tion without perfor­mance compro­mise
