Replace PARKER FO Series High Efficiency, Long Life Micro filter Cartridges
Recommends filter cartridges be changed when they reach 25 psi differential or in accordance with
your company’s fuel handling procedures. The amount of contaminant a cartridge will hold before that
point depends on many factors, the key one being the nature of the contaminant itself. A hard, particulate contaminant has very different filtration characteristics than a soft, gel-like contaminant.
Accurately estimating the life of a cartridge in a given application, therefore, is extremely difficult.
However, when a cartridge has been sized for an initial pressure drop of 2 psi, the following rule of thumb is often employed for particulate contaminants: A 1 or 2 micrometer cartridge will hold up to 3 pounds of contaminant, and a 5 micrometer or greater cartridge will hold up to 5 pounds.
Reduced Flow Rate Effects
The filter sizing above is based on a 2 psi initial pressure differential which is a widely accepted industry standard. However, where heavy contaminant loads are anticipated, a substantial savings in operating costs for cartridges and filter change labor can be achieved by over-sizing the filter. Reducing the flow rate per cartridge in half will increase the contaminant capacity of each cartridge by 30 to 50 percent. This means that doubling the size of the filter will increase the total throughput between cartridge change outs by as much as three times.
Benefits
1. Large Surface Area – Allows high flow rate with low initial pressure drop and maximum contaminant holding capacity.
2.Resin Impregnated Media – Maintains strength, resists effects of water and heat.
3. 75 psi Collapse Strength – Heavy gauge carbon steel end caps and center tube give
safety margin against pressure surges.
4.Coated Steel Components – Resist corrosion from most industrial fluids.
5.Corrugated Media – Prevents pleat pinch-off, assuring all filtration media is utilized.
6.Buna-N Gaskets – The best general gasket material available assures positive seal in most
fluids.
7.Thermoset Bonding Material – Durable end cap-to-media bond prevents internal bypassing.
8.Threaded Base Filter Elements – Available for easier installation.
