The main application of the DIL 554 Aerosol Dilution System is in the verification of test aerosols for testing clean rooms.
Standards
VDI 3491-15
VDI 3491-6
VDI 2083
ISO 14644-3
Guideline EN ISO 14644-3 defines the necessity of appropriate dilution systems when using test aerosols for verification. According to standard VDI 2083 for testing clean rooms and work benches it is compulsory to carry out measurements with increased concentrations in the incoming aerosol.
Benefits
- designed for mobile use (no auxiliary pressurized air and additional exhaust needed)
- battery-operated with status indicator (optional with power adapter)
- constant and reproducible aerosol dilution even under changing operation conditions
- continuous control and display of actual dilution ratio
- long-term lifetime and reliability, minimum maintenance required
- precise operation in both over and under pressure mode
Applications
- validation of laminar air flow boxes/benches and clean room/environments
- evaluation of filtration efficiency
- measurement of highly concentrated aerosols
- aerosol research
Accessories
- carry case for one dilution system DIL and one aerosol generator
