Pall Portable Fluid Purifier

The Pall Portable Fluid Purifier was specially developed to ensure that the working properties of the fluid being purified are not degraded. Unlike systems that use desiccants, high vacuum or added heat, the Pall Portable Fluid Purifier employs spinning disk and low vacuum dehydration technologies, which are the most gentle to fluids.

Designed to prevent pollution, increase equipment reliability and performance, and reduce costly maintenance, the Pall Portable Fluid Purifier will automatically remove water, gases, solvents and particulate from hydraulic fluids, lubrication fluids, coolants and synthetic and organic ester based liquids.

Easy to connect, simple to operate and requiring minimum operator attention, the Pall Portable Fluid Purifier uses standard line voltage and connects to your system using inlet and outlet hoses.  There are no adjustments to make, no controls to set, no other hookups necessary.

Return on Investment

• Low operating and maintenance costs make the Pall Purifier cost effective and minimize the investment payback period

 

 

Contaminated fluid is drawn into the spinning disk vacuum chamber through a mesh strainer.  A float valve regulates the inlet flow, keeping it equal to the output of the discharge pump.

Oil entering the vacuum chamber impinges on the center of the spinning disk.  As the disk rotates, oil flows outward to the edge of the disk, progressively decreasing in film thickness.  The oil is thrown off the disk and breaks into very small droplets yielding a large surface area.

Maximizing surface area directly increases the water removal rate of fluid dehydrators.  Pall’s unique spinning disk technology produces a uniform surface area significantly greater than that achieved by other mass transfer devices.

Ambient air is drawn into the vacuum chamber through an air breather filter.  The air expands to approximately five times its former volume, resulting in an 80% reduction relative humidity.  Water, air and solvents are carried from the vacuum chamber with the dehumidified air flow as exhaust.

Dehydrated fluid from the vacuum chamber exits the purifier via a discharge pump through a 3µm absolute non-bypass discharge filter exhibiting an extremely high dirt capacity.

The PAC portable fluid purifier is easy to connect, simple to operate and requires minimum operator attention.  It uses standard line voltage and is easily connected to your system using inlet and outlet hoses.  There are no adjustments to make, no controls to set; unit is self-contained.

System Reliability
Proven system with more than 3,000,000 operating hours logged.

Easily Portable
Small, lightweight, and mounted on wheels for high mobility.

Service Indicators
Indicator lights signal the condition of the filters when element change is required.

Unattended Operation
Automatic controls will safely shut down the system if fluid levels and pressures venture outside normal limits.

High Efficiency Particulate Removal Filter
Solid particulate removal is achieved using a highly efficient 3 µm absolute filter with a minimum 99.5% gravimetric efficiency when tested per MIL-PRF-81836, and ß3 [5(6)] ≥ 2000, when tested per ISO 16689.

Unique Operating Principle
Removes free and dissolved water; as well as free, entrained, and dissolved gases, and particulate contamination.

 

When you need to know water contamination levels, the Pall water sensor is a fast acting, highly repeatable in-line device measures relative humidity and temperature which are used to calculate parts per million (PPM) water content.  Fluid relative humidity is the amount of dissolved water in a fluid expressed as a percentage of the amount of water necessary to cause 100% saturation.  This in-line device provides instant feedback on water contamination of the fluid being purified. The digital display can be used as a simple indicator of water contamination.
