Features
Gas-tight Test Channels: Ensure no leakage during aerosol or gas testing.
Modular Structure: Adaptable to different filter sizes and test requirements.
High Degree of Automation: Software-based test sequences minimize manual intervention.
Standardized Reporting: Automatic generation of test reports for efficiency and adsorption results.
Versatile Testing Mediums: Support for aerosols (salt, oil, dust) and gases (NO₂, H₂, n-butane, toluene, SO₂, NH₃).
Accessories
(1) Filter adapters – enable secure mounting of different filter types.
(2) Aerosol generators – for fine dust, DEHS, NaCl, KCl.
(3) Gas dosing units – for standard and pollutant gases including NO₂, H₂, n-butane, SO₂.
(4) Gas sensors – FID, UV-fluorescence, CLD for real-time detection.
Test Procedures
Preparation:
Select the filter type and confirm its dimensions fit the test duct.
Set up the appropriate aerosol or gas medium according to the test standard.
Testing:
Insert the test filter into the filter adapter and mount it in the test duct.
Define test flow rate and start the automated sequence.
The system measures differential pressure, dust loading, fractional efficiency, and adsorption/desorption curves.
Data Analysis:
Collect data via software and analyze filter performance.
Generate standardized reports for quality assurance or R&D documentation.
Maintenance Information
Ensure all gas and aerosol lines are properly sealed to prevent leaks.
Periodically calibrate sensors and aerosol generators to maintain measurement accuracy.
Keep the system clean and check mechanical components for wear.
Ensure ventilation and follow safety guidelines when working with gases.
