RFU 564 Regulated Flow Unit
Compact regulated-flow unit providing adjustable and time-stable air or nitrogen flow for both suction and supply operation, simplifying aerosol test setups and conditioning workflows.
Model Overview
| Model | Group | Positioning | Core fit |
|---|---|---|---|
| RFU 564 | Regulated airflow unit | Compact controlled-flow source for underpressure and overpressure aerosol setups | Defined airflow generation, dilution air, purging and aerosol transport |
Key Features
Stable regulated airflow
Closed-loop flow control compensates changing pressure conditions to maintain the selected airflow over time.
Suction and supply modes
The unit supports both intake operation under negative pressure and supply operation under positive pressure.
Integrated clean-air path
A controlled side-channel blower draws air through a high-performance HEPA filter before delivery to the test setup.
Compact system replacement
The RFU 564 can reduce the need for separate blowers, valves, flow meters, filters and associated piping in laboratory setups.
Touchscreen operation
Flow settings and operating status are available through the integrated touchscreen for rapid setup.
Remote integration
An RS-232 interface supports incorporation into automated aerosol-conditioning and test-system workflows.
