DIL 550: 0.3-100 l/m

The Aerosol Dilution System DIL 550 is designed to accurately dilute aerosols to produce a defined particle concentration for certain measuring tasks. The main application of the dilution system DIL550 is the verification of test aerosols for testing clean rooms. DIN EN ISO 14644-3 defines the necessity of appropriate dilution systems when using test aerosols for verification.

In the applied principle that corresponds to the standard VDI 3491-15, particles are removed from the sample according to the specified dilution ratio. The particle size distribution remains unchanged.

  • Constant and reproducible aerosol dilution even under changing operation conditions
  • Continuous control and display of actual dilution ratio
  • By default aerosol dilution ratio of 1:100 at 28,3l/min intake flow rate of a particle counter
  • Number of dilution systems can be cascaded easily
  • Vertical flow duct of aerosol guarantees minimal deposition also for coarse particles
  • Designed for mobile use (no auxiliary pressurized air and additional exhaust needed)
  • Long term lifetime and reliability, minimum maintainance required
  • Precise operation in both over and under pressure mode
  • Modifications to user defined requirements (flow rates, dilution ratio) available
  • In combination with particle counters self-priming system
  • Dilution systems of series DIL can easily be cascaded in order to achieve higher dilution ratios. E.g., by cascading a 1:100 and a 1:10 dilution system an overall dilution ratio of 1:1000 can be achieved.
  • Validation of laminar air flow boxes/benches and clean room/environments
  • Evaluation of filtration efficiency
  • Measurement of highly concentrated aerosols
  • Basic aerosol research
