Coralon Filter Elements

With Pall’s Coralon™ hydraulic and lube oil filter elements, protecting fluid systems has never been easier! 

 

A simple and risk-free upgrade that does not require any adapters or special tools and is directly interchangeable with the current Ultipor® filter installations, Coralon lube oil filters and hydraulic fluid filters are the ideal solution for those looking to achieve optimum performance and yield at lesser costs.

 

Benefits of switching to Coralon filter elements:

 

• Upgraded filtration with Stress Resistant Media Technology (SRT) at no extra cost
• Proven improved performance, irrespective of age or condition
• Reduced equipment operating costs
• Fluid and temperature compatibility
• Optimum performance in equipment protection; increase equipment output
• Anti-static, greatly reducing static charge build-up
• Cost reduction of up to 20%
• These hydraulic and lube oil filter elements produce up to 15x cleaner fluids and have 16x more consistent performance throughout the filter’s service life.

 

Why Choose Pall’s Coralon Filter Elements?

Overcoming the challenges faced in lube and hydraulic fluid applications, Pall’s Coralon filters provide an easy and advanced upgrade in oil filter media. These hydraulic fluid filter elements deliver improved and consistent performance that protect fluid systems while producing up to 15x cleaner fluids, and returning up to 20% savings in overall filtration costs.

Pall’s Coralon (anti-static) hydraulic oil filter elements provide:

• Consistent, high particle capture efficiency (high dirt-holding capacity)
• Low pressure drop for small envelop size and longer life
• Added benefit of significantly reduced static charge generation
• Optimum performance even under system stresses throughout the duration of the filter life, and;
• Production of consistently cleaner liquid

 

Overall, there is no drop in filter performance or efficiency, until the filter is blocked. And when the filter gets blocked, it indicates that the contaminants are in the filter rather than in the machines, all of which add up to improved equipment performance and longevity.

 

Coralon anti-static filters also eliminate problems related to electrostatic charging and its effects, such as:

• Noise, sparking, component and filter damage
• Varnish formation
• Charge generated by housings and pipes
• Excess electrostatic charge created by standard glass and paper media.

 

Advanced Lube and Hydraulic Fluid Filter Element Design

Coralon hydraulic and lube oil filter elements incorporate Pall’s advanced filter medium pack construction that benefits from Stress-Resistant filter medium Technology (SRT) along with,

• blended layers of fiberglass
• optimized construction for low differential pressure and stress resistance
• tapered pore construction
• uniform pore size control layer and
• epoxy resin bonded fiber structure.

 

Coralon Filter Performance

The effectiveness of a filter in an operating system reduces due to conditions such as varying flow, cold starts, shock and vibration. 

The Cyclic Stabilization Test (based on SAE ARP4205) examines the effects of cyclic flow conditions and the potentiality of the capture and retention characteristics of the filter in retaining dirt and contaminants. The result showed an improved filter performance reporting method, that simply tells the user via ISO Codes, the level of contamination control that can be maintained throughout the filter’s service life. *

A critical measure of a filter’s performance is its ability to sustain fluid cleanliness throughout its service life. Only Coralon filters have proven to produce sustained fluid cleanliness over the filter’s full life, compared to Ultipor® filters.

 

Measuring Filter Performance - the Cyclic Stabilization Test (based on SAE ARP4205):

Conditions such as varying flow, cold starts, shock and vibration can potentially reduce the effectiveness of a filter in an operating system.

 

The Cyclic Stabilization Test examines the effects of cyclic flow conditions and dirt loading on the capture and retention characteristics of the filter. The result is an improved filter performance reporting method that simply tells the user via ISO Codes (see Table 1) the level of contamination control that can be maintained throughout the filter’s service life.

 

Filter Performance Ratings

Pressure Rating: 

• 10 bard (150 psid) minimum for Coreless Ultipor filter elements (polymer end caps) and for use in filters with bypass
• 20 bard (300 psid) minimum for Ultipor filter elements (metal end caps and core) and for use in filters with bypass
• 210 bard (3,045 psid) minimum for Ultipor high strength filter elements (metal end caps and core) and for use in filters without bypass

 

Temperature Range:

 

• Fluorocarbon: -29 °C (-20 °F) to +120 °C (+250 °F)
• Nitrile: -43 °C (-45 °F) to +120 °C (+250 °F)
• Note: Maximum 60°C (140°F) in water-based fluids
• Seals: Fluorocarbon or nitrile
• Fluid Compatibility: Compatible with petroleum oils, water glycols, water-oil emulsions, and high water-containing fluids.
• Filter Element Hardware: Cored filters elements - Corrosion protected end caps and core Coreless filters elements - Polymer end caps only.

 

All Coralon filter elements are manufactured by Pall to rigorous procedures and strict quality controls. Elements are validated to the following ISO test protocols:

 

• Filter Ratings:
  • Cyclic Stabilization Test (80% Δp ) based on SAE ARP4205
  • ßx(c)≥1000 multi-pass filter ratings (per ISO 16889)
• Element Collapse Pressure Rating (ISO 2941)
• Fluid Compatibility (ISO 2943)
• Flow vs. Pressure Drop (ISO 3968)
• Flow Fatigue (ISO 3724)
• Fabrication Integrity (ISO 2942)

 

A critical measure of a filter’s performance is its ability to sustain fluid cleanliness throughout its service life. This graph compares a Coralon 7μm(c) rated hydraulic fluid filter to an Ultipor III filter and four competitors’ products with equivalent ratings.

 

Only Coralon filters produce sustained fluid cleanliness over the full life of the filter.

1. How effective are Coralon filters in fluid cleanliness?

The Coralon filter is consistent in its performance and efficiency throughout the filter life. When tested against other filters in the market, only Coralon filter displayed sustained fluid cleanliness over the service life of the filter. 

The filter can be used till it is blocked by dirt and contaminants, that would have, otherwise, adversely affected the equipment and operations.

 

2. In addition to improved performance, what difference will I see?

The Coralon Filters upgrade previously used elements of standard medium grades (Z,P,N,S,T). The new elements have a medium code of ‘C’ in place of the existing U,D,K,M,X codes in the current filter element part number.

 

3. How easily can Ultipor filters be replaced with Coralon filters?

Ultipor filters are easily replaceable with Coralon filters as they have the same fit, form and function. They are directly interchangeable with no adapters or special tooling required, all for the same price.

 

4. What are the performance ratings for Coralon filters?

The Cyclic Stabilization Test (based on SAE ARP4205) delivers the following performance rating:
