Tube filter (tubular filter)

Compact stainless steel tubular filter for individual piping applications.

Data sheet

Product information

The tube filter, also known as a tubular filter, is the ideal solution for filtering liquids, viscous media and gases directly in piping systems. It protects pumps, fittings and heat exchangers from particles and ensures trouble-free operation. Thanks to its compact design and the possibility of customization, the tube filter is suitable for demanding applications in the chemical, energy and food industries.

Magnetic inserts for strainers, filters and strainers

Armaturenfabrik Basket strainer Duplex strainer Simplex strainer Magnetic rod Magnetic insert Option Magnetic filter Stainless steel

Our magnetic inserts are the perfect addition to strainer inserts in strainers, basket strainers, simplex strainers and duplex strainers. They ensure the reliable separation of ferromagnetic particles such as iron, steel chips or magnetite, which occur in many process media. This increases operational reliability and extends the service life of your systems.

Our features:

  • Integrated magnetic rods made of high-performance neodymium for maximum holding force
  • Combined filtration: mechanical sieving + magnetic separation
  • Customization: For all common screen geometries and filter types
  • Material: Stainless steel for magnetic holders, corrosion-resistant and hygienic
  • Easy cleaning: Magnetic bars are easy to remove and easy to maintain

FAQs

What is a tubular filter?

A tubular filter is a compact pipe filter that is integrated directly into pipelines and removes particles from liquids or gases.

Liquids, viscous media and gases – also aggressive media with stainless steel design.

Via screw plug or blind flange, optional quick-release fastener for fast screen change.

Yes, e.g. with heating jacket, magnetic rod, differential pressure indicator or special connections.
