Multi-function Bag Filters

A simple and cost-efficient alternative to sand filters, multi-function bag filters remove particulate matter from small systems, trap detritus vacuumed from large tanks and are ideal for space-constrained plant-rooms.

Versatile. Compact. Easy to install.

This unidirectional pressure filter (working pressure 0-100 PSI) is suitable for a wide range of filtering and water treatment applications. Compatible with filtering media for carbon purification or biological filtration.

Why Clients Prefer AAT Multi-function Bag Filters

Ideal for small systems

  • Simple and robust alternative to sand-filtration in small systems.
  • Often specified for systems under 20,000 litres (depending on factors and circumstances).
  • Perfect for space-constrained plant rooms.

Easy to install

  • Mount onto a base only, or a wall and a base, or a wall only.
  • Four in-built mounting positions so the unit can be ‘rotated’ (vertical axis).
  • No fixed lid-handles jutting out either side -removable handles enable lid removal in small spaces.
  • Pipe size reducers enable connections of 4” and 2″.

Smart design

  • Designed by AAT personnel with intimate knowledge of the issues and challenges of onsite LSS construction.
  • Easy bag removal due to built-in bleed vent in the lid and hinged basket handle.
  • Connects easily to new and existing infrastructure.
