Product ID: Cintropur-NW340-1-1/4in-Port



Cintropur NW340 Semi-Industrial Centrifugal Filter Housing with 1 1/4″ Ports

The CINTROPUR® NW340 housing is designed for semi-industrial use due to it’s higher port sizes and increased flow rates however can also be used for residential and agricultural applications.

Made entirely from premium quality synthetic material, CINTROPUR® filters are ideal for use with food products and drinking water. The CINTROPUR® vane changes the liquid flow using centrifugal motion, forcing the larger particles down into the lower bowl, depending on the chosen filter sleeve micron-size.

The basic principle of CINTROPUR® housings are for the protection of sanitary domestic, collective and agricultural water supplies by filtering out the solid particles (earth, sand, rust, etc.) suspended in the water. Ideally, the protection filter will be placed at the entrance of the installation, to protect all the devices connected after.

Advantages of using CINTROPUR® Filters

  • High and constant flow rate.
  • Low-pressure drop.
  • Centrifugal pre-filtration with a cyclonal effect.
  • Robustness and reliability.
  • Fast and easy flushing out via the drain cock (on NW range).
  • An exclusive system, ecological and not expensive (inexpensive, replaceable filter sleeve).
  • Permanent visual control of the filter sleeve (transparent bowl)
  • Optimal filtration technique through a filter sleeve and a centrifugal vane.
  • Innovative engineering allows for every part to be replaced if there were ever a fault, so you never have to purchase the full system again. This, in turn, makes them much more environmentally friendly than other water filter housings by eliminating a significant amount of plastic waste.

Applications of Use

Protection of sanitary networks supplied with domestic water, rainwater or well water (residential property, schools, restaurants, etc). Filtration of water before softeners, reverse osmosis or treatment by ultraviolet.

Protection of sanitary networks, machine tools and all industrial machinery for water treatment. Filtration of water before high-pressure cleaning machines (100 to 200 bar / 1,500 to 3,000 psi) and very high-pressure cleaning machines (1,500 to 2,500
bar / 21,000 to 35,000 psi).

Filtration of watering (spraying) installations, filtration of water for animals, filtration of rainwater and well water.
