Model Overview
| Model | Configuration | Primary use | Selection note |
|---|---|---|---|
| DIL 541/C | 1:10; 28.3 L/min | Self-adjusting 1:10 aerosol dilution system for 28 | Select DIL 541/C for automatically controlled 1:10 dilution with a 28.3 L/min cleanroom particle counter. |
Key Features
Automatic dilution-ratio control
The dilution ratio is automatically adjusted and monitored to maintain defined aerosol conditioning during changing operating conditions.
Digital status communication
Supports status communication for integration with particle counters, test benches and supervised measurement workflows.
Closed aerosol path
Directs the complete intake flow of the connected particle counter from the sampling point through the dilution system.
Isokinetic capillary sampling
The fluidic design minimises changes to the aerosol particle-size distribution during splitting and recombination of the flows.
Positive and negative pressure operation
Designed for operation under overpressure or underpressure within the published counterpressure limits.
Cascadable configuration
Can be connected in series when a larger overall dilution factor is required for the measurement task.

Applications
Verification of cleanroom test aerosols
Reduces high upstream challenge-aerosol concentrations to a range suitable for optical particle counters during cleanroom and clean-air-device testing.
Laminar-flow and safety-cabinet acceptance
Supports acceptance measurements on laminar-flow boxes, work benches, safety cabinets and smaller cleanroom installations.
Filter separation-efficiency measurement
Extends the usable concentration range of particle counters in upstream and downstream filter-efficiency measurements.
Highly concentrated aerosol analysis
Conditions concentrated aerosol samples before particle counting to reduce coincidence-related measurement errors.
Aerosol research
Provides a defined dilution stage for experimental aerosol generation, transport and particle-size-distribution studies.
Measurement-range extension
Allows particle-measurement instruments to analyse aerosol concentrations that would otherwise exceed their operating range.
