LOFMET
Metallic filter cartridges


LOFMET filter cartridges are cylindrical filter elements fabricated with ss 304 or 316 mesh fabric. They are available with a plain or pleated (enlarged filter area) outer surface.

LOFMET filter cartridges are especially recommended for high temperature and pressure conditions, i.e. as commonly is the case with high viscous liquids. They may be chemically, mechanically or thermaly cleaned and are therefore often economical and environmental alternatives to single use cartridges in low solid contaminated liquids.

Process data

  • differential pressure : 0,1 bar
  • bursting pressure : 10 bar
  • max. pressure drop : 2,5 bar
    (to avoid strong mechanical blocking by solid particles)
  • max. operating temperature : 250°C
  • max. flow rate : 75 l/min
    * (water / delta P = 0,15 bar / 9 3/4" filter cartridge)
Length

9 3/4" (248 mm) plain + pleated, 19 1/2" (496 mm) plain, 29 1/4" (744 mm) plain and 39 1/2" (1000 mm) plain

 
Diameter

O.D. 65 mm - I.D. 27 mm or 36 mm

 
Material of construction

Core and end caps : SS 304 or 316, wire mesh SS 304 or 316

 
Gasket material

Flat gasket : Buna N (max. 150°C), EPDM (max. 175°C), FPM (max. 200°C) or PTFE (max. 250°C)

 
Max. differential pressure
The plain filter element can withstand, without deformation, 20 bar of differential pressure.
The pleated filter element size 9 3/4" (248 mm) can withstand, without deformation to 6 bar of differential pressure. It is good practice to clean or replace the filter elements when the pressure drop reaches 2,5 bar.
 
Temperature range

The plain filter element finds application in a range from -50°C to +250°C.
The pleated filter element can be used in the range of temperature listed below depending upon the type of seal between ends and filter media.

  • option K (epoxy resin for food use) : -54 to +150°C
  • option C (polyvinyl resin for industrial use) : -10 to +95°C
 
Filter fineness

10, 25, 50, 80, 100, 140, 200,250, 300, 400, 500 and 1000 µm

 

Filter area

plain surface : 9 3/4" cartridge = 0,05 m² (all welded)
pleated surface : 9 3/4" cartridge = 0,15 - 0,20 m²
 
Connections :
double open end cartridge (DOE) = standard
R 1" threaded single open end (SOE) = special
(option for back washing)
