Stamoclean CAT221

Self-cleaning backflush filter for inlet or outlet sampling in wastewater treatment plants

  • ©Endress+Hauser

Stamoclean CAT221 provides filtrate for continuous online monitoring of municipal and industrial wastewater. Its self-cleaning crossflow filter avoids filter blocking, thus increasing your process safety. Thanks to a minimized dead volume, it reflects changes in your process promptly and shortens the response time of your downstream measuring devices. Stamoclean CAT221 comes pre-mounted to streamline installation and commissioning.


  • Reduced operating costs thanks to automatic and chemical-free cleaning

  • Efficient backflushing with compressed air or rinse water

  • Easy and fast replacement of filter elements

  • Short response time of downstream measuring devices thanks to low dead volume
