설명
Please Note: The following information is provided to support existing users of Pall Cleanliness Cabinets (PCCs) for technical reference and order of consumables and spare parts. The complete cabinet assemblies are no longer available to purchase.
The PCC-FR Component Cleanliness Cabinet has been specifically developed by Pall to assess the cleanliness level of components or manufactured parts by flushing them out, simulating their functional operation under turbulent flow conditions. This is accomplished by passing a filtered, low viscosity fluid through the component or finished part under turbulent flow conditions to flush contaminants from surfaces and transport them to a test membrane for subsequent analysis.
The PCC-FR enables operators to assess the cleanliness levels of manufactured parts and components in accordance with ISO 18413, ISO16232 and VDA 19 procedures.
Features
- Small footprint and ergonomic design
- Simple to install and operate
- Stainless steel and carbon steel construction
- PLC controlled operation
- Pressurized solvent flushing and recycling circuits
- Programmable flushing, blowing and drying sequence
- Requiring only a power and pressurized air source
- Fitted with adjustable feet, requiring only an electrical power supply and pressurized air source
Principles of Operation
During the test filtered solvent is passed through the component, flushing contaminants downstream and capturing them on an analysis membrane. After passing through the membrane the solvent is filtered to 0.2 μm and then returned to the test component (a re-circulating loop) to continue the flushing procedure.The flushing process is stopped when the ISO or VDA standard ‘End Point’ is reached. The overall extraction procedure is finalized with a blowing and drying sequence that ensures both the component and the circuit are entirely free of solvent traces.

Reynolds (Re) Number: A non-dimensional number that provides a qualification of the degree of turbulence within a pipe or hose
The flow conditions in a pipe or a hose can be assessed using Reynolds Number as follows:
Re = 21,200 x Q / (V x d)
Q = Flow rate (L/min)
d = Pipe internal diameter (mm)
V = Kinematic viscosity of fluid in cSt (mm2/s)
Laminar Flow: Reynolds Number < 2,000
Transitional Flow: Reynolds Number 2,000 - 4,000
Turbulent Flow: Reynolds Number > 4,000
Examples of simple applications
| Flow Rate (L/min) | Pipe Diameter (mm) | Re |
| 2 | 5 | 4,240 |
| 10 | 25 | 4,240 |
| 20 | 50 | 4,240 |
