Valairdata II
Since 1990 and the launch of the unique VALAIRDATA aerosol integrity test system, the aerosol test method has become widely accepted in a variety of applications and industries as a routine
method for integrity testing air filtration systems. The VALAIRDATA II integrity test instrument is a second generation design offering further practicality in air filter testing.
The VALAIRDATA II combines the sound principles of aerosol testing, as recommended in the ‘PDA’s Sterilising Filtration of Air - Technical Report #40’, with a compact, portable and ergonomic
design reducing test times and improving multi cartridge system sensitivity.
The VALAIRDATA II aerosol test is correlated to an aerosolised Brevundimonas diminuta and bacteriophage (such as Enterobacteria phage MS2) challenge.
Aerosol methods are rapid, can identify filter non-integrity on very large systems, allow immediate use of filter systems after testing as drying is not required and provides direct measurement of filter performance for gas filters.
- 30 second test time for a single 10¨ (250 mm) cartridge challenge
- Results correlated to aerosol bacterial and viral challenge
- Increased sensitivity compared to liquid based tests especially on multi-cartridge systems
- Built-in test instrument system integrity check
- Well established with over 200 current VALAIRDATA II users
- Fully validated secure option design to GAMP 4 Guidelines and meets the FDA’s 21CFR11 requirements
- Stores up to 200 test results and supported with software for PC download
- PDA recommended for use where filtered gas not in direct contact with exposed sterile product or surfaces
