Selexsorb Filter Cartridges and Systems

Fewer fluid change outs, increased equipment life

Cartridges fit most standard filter housings

• Lifting handle - for convenience in handling.
• Ambient - Perforated steel or expanded metal ambient provides added strength.
• Lifting tab - for convenience in handling.
• Polyester media retainer - under the ambient for superior chemical resistance and media retention.

Selexsorb  is a adsorbent specifically designed for use with gas turbine lube and hydraulic control fluids. Another application is steam turbine EHC control industrial hydraulic systems. The unique composition of this adsorbent maintains the original, superior properties of these fluids for prolonged periods. This media, in cartridge form, is available through your authorized distributor.

When systems are used in conjunction with a fluid maintenance program designed by your supplier, you can expect the following benefits:

• Longer fluid life- Fluid change out intervals are greatly lengthened, and the fluid is maintained in near-original condition.
• Increased equipment life- A result of continual removal of acid phosphates and moisture.
• Standard sizing- Designs fit most standard filter housings
• Superior efficiency- Maintains total acid number (TAN) much more effectively than fuller’s earth.

When systems are used in conjunction with a fluid maintenance program designed by your supplier, you can expect the following benefits:

Advantages versus other filter types:

The key features of Selexsorb  cartridges and systems over conventional fuller’s earth and activated alumina are as follows:

• Fuller’s earth- Low comparative removal of acid phosphates; acid removal relies upon neutralization with media surface. Major disadvantage is the presence of metal impurities.
• Activated alumina- Acid capacity is 2-3 times that of fuller’s earth; relies on neutralization of media surface with acid phosphates. Again, basic metal impurities can create similar problems as with fuller’s earth through extended use.
• Selexsorb - Similar acid capacity to activated alumina types. However, acid phosphates are adsorbed or chemically bonded to the surface of the filter media as they are formed.

A neutralization reaction is not involved nor are free ionic metals liberated in the hydraulic system. Also can remove moisture but preferentially bonds acid phosphates in lieu of moisture. Cartridge life can be extended 2-3 times versus fuller’s earth. Flow rate in auxiliary filter system must be slowed to allow chemical exchange to occur. Normal rate is 1/2 GPM maximum per 7” x 18” Selexsorb  cartridge.

NOTE: Ideally, acid number should be maintained below a level of 0.1 TAN. Similarly, a moisture level of less than 0.1% (by weight) is desirable.
