Filtration Solutions For Commercial Aircraft

Improved Reliability of Engine Lube Systems

On any Powerplant, the lubricant fluid is a natural repository for particulate contamination. This contamination comes from several sources. Built-in Debris Wear debris generated during operation Environmental contamination during maintenance If this contamination is not removed it will be recirculated through the fluid system and cause numerous problems. 

Benefits Of Fine Filtration

Fine filtration removes harmful contaminants from the lube system and this will:

• Improve operating reliability and performance
• Increase component service life
• Reduce maintenance costs

Improved Reliability of Engine Fuel Systems

The fuel system can contain particulate, water and biological contamination. This can cause both immediate and longer-term damage. 

Problems Caused by Contamination

Fuel system contamination can:

•  Block or erode nozzles and valves
• Cause wear of fuel system components
• Cause leakage (e.g. particles trapped under valves)
• Cause corrosion of fuel system components
• Foul sensors Gum together surfaces
• Cause fuel degradation

Benefits Of Fine Filtration

•  Improves fuel system and component reliability
• Maintains appropriate system fluid cleanliness
• Reduces maintenance costs 

Applications

Pall has been supplying lube and fuel elements to the major aerospace engine OEM's since the 1970's. These parts have to undergo a stringent qualification test program to meet the OEM specification requirements.

Pall engine applications include:

CF6, GE90, CFM56 series, GP7200, GEnx, LEAP-X, JT8, JT9, PW2000, PW4000, PW6000, GTF1000, RB211, Trent, V2500 and XWB. 

Improved Reliability of Hydraulic Systems

The hydraulic systems that control aircraft require equipment performance with long term reliability and state-of-the-art technology. By removing particulate contamination, Pall’s advanced filtration solutions provide consistent cleanliness in fluid systems throughout their expected life cycle.

Benefits Of Fine Filtration

Fine filtration removes harmful contaminants from the hydraulic system and this will:

• Improve component reliability
• Increase component service life
• Reduce maintenance costs

Applications

Palls Filters are qualified for all the major civil and military aircraft programs.

OEMS include: Airbus, Boeing (military and commercial), Embraer, Gulfstream, Cessna, Lockheed, Northrop and Sukhoi among others.

Ground Support Equipment

To complement the flight-approved filter solutions, Pall offers a range of products for ground support equipment (GSE) and test rigs.

Fluid Recycling

For commercial operators, hydraulic, lubrication and cooling fluids account for a significant part of their annual operating costs. Airlines therefore require a process to extend fluid service life and also reduce the procurement and disposal costs due to waste fluids. The portable fluid purifier provides an environmentally friendly solution to remove free and dissolved water and gases, solvents and particulate contamination.

Fluid Cleanliness Monitor

Monitoring the cleanliness of lubricants, hydraulic fluids or fuels, can provide advance warning of a pending component malfunction and/or system failure.

The PCM400 is a portable diagnostic monitoring device which displays the fluid cleanliness level. Unlike other instruments the results are not affected by the presence of air, water or high particulate levels

Water Sensor

The water sensor measures moisture content in the fluid as a percent of the water saturation level of the fluid. It provides a display showing % saturation or ppm. The sensors can be portable or they can be permanently installed in the fluid system

Flushing Filters

To remove damaging debris on a single pass basis, during initial 'Green Run‘ or flushing of fluid systems, it is necessary to employ high efficiency, fine filtration. This minimizes the possibility of catastrophic component failure and reduces component wear and damage to component surfaces. 

Improved Cabin Air Quality

Pall ‘true HEPA’ cabin air filters remove dust, allergens and microbes (‘microbes’ includes viruses and bacteria) from the air recirculated into the cabin and cockpit. This helps to provide a safe, healthy and comfortable environment for the passengers and crew.

Pall Cabin Air Features

• True HEPA filters (>99.999% microbial removal efficiency)
• High dirt holding capacity
• Minimum pressure loss
• High collapse strength
• High adsorption capacity for odors / VOCs (with optional carbon filters)

Benefits

• Reduced weight
• Extended filter element service life
• Fewer filter changes / reduced maintenance costs
• Control of microbial and viral contaminants without the need for chemical additives, coatings, or other surface treatments.

Applications

• Pall provides cabin air filters for all the major commercial aircraft programs including:
• Airbus, Boeing, Bombardier, Embraer, GlobalExpress and Saab.

The solution can be either the complete cabin air filter assembly (including housing and HEPA filter element) or the cabin air filter element only
