Metal High Flow Filters

Larger Filter Area, Longer Filter Life

Pall ‘Rigimesh’ and ‘PMF’ range of cleanable metal cartridges has been extended to include a high area, large bore version. These are specifically designed to provide a very high surface area, up to 4.1 m2, for handling large flow rates. Manufactured from Rigimesh or PMF medium to give very low clean differential pressure drops. Absolute removal from 2.5 micron up to 105 micron in liquids and .25 to 85 micron in gases.

 

 

 

Features Benefits
  • Large diameter high surface area 
  • Low clean differential pressure
    High dirt capacity
    Longer filter Life
    Can replace up to 30 conventional metal filters
  • More flow per cartridge
  • Smaller systems
    Quicker changeout
  • Absolute removal ratings from 2.5 up to 225  µm
  • Offers consistent and reproducible filtration throughout filter life
    Single housing offers wide variety of removal solutions
  • Cleanable
  • Easier to clean than conventional metal filters

Applications

Typical Applications

  • Used where high flow rates combined with high temperatures
    preclude the use of polymeric products.
  • Gas compressor inlets to reduce the effects of fouling.
  • Catalyst protection, to increase catalyst life.
  • Heat exchanger protection to reduce energy costs.
  • Pump protection to increase pump life.

* For fluids compatible with the filter element at the stated temperature


To correct for different viscosity, use the following formulas:

GAS  Differential Pressure x (Gas viscosity/.018)
LIQUID  Differential Pressure x Viscosity

These values are for the media only.


You will need to add the tubesheet p as follows:

GASES  The differential pressure caused by the connections is negligible at .001mbar and can be ignored
LIQUIDS  The differential pressure caused by the connections can be taken as constant for each application at 55 mbar
