As you use your FinePointe WBP system, some parts will wear out and may need to be replaced. Proper care and maintenance will help ensure consistent results and that your equipment investment will last for years.
Consider replacing/servicing the following components on a scheduled basis:

Tubing:

• Calibrator Tubing
• Bias Flow Filter, Tubing, and Isolation Resistor

Screens:

• Pneumotach Screens

O-Rings:

• 22mm Port O-ring
• Transducer O-rings
• H₂O Bottle O-ring
• Pneumotach O-Rings
• Chamber O-Ring
• Bias Flow Adaptor O-Ring
  
  

Miscellaneous:

• Nebulizer

The frequency of replacement will depend on a variety of factors that may include: testing environment, frequency of use, aerosol exposure, and proper care of equipment throughout. Good Laboratory Practices (GLP) and routine equipment maintenance/servicing are recommended. At a minimum, tubing and screens should be replaced annually.

See FPWBP Application Manual for proper care and cleaning of the FinePointe WBP system.
