DIL 554/H Dilution System

DIL 554/H Dilution System for static dilution (1:100) of aerosols at static air flow rate (56,6 L/min) for mobile operation

The main application of the DIL 554/H Aerosol Dilution System is in the verification of test aerosols for testing clean rooms.

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

From the aerosol flow to be diluted, a sample is passed through a thin capillary. The particle concentration of the capillary flow rate remains unchanged, whereas a HEPA filter removes nearly all particles from the bypassing flow rate. After the capillary and filter both flows are remixed. The dilution ratio results from the ratio between the two single flow rates.
