AFC 132 Filter Media & Small Filter Element Test System
Flexible test system for filter media and small filter elements, supporting pressure-drop, gravimetric-efficiency, fractional-efficiency and dust-holding measurements across multiple air-filter standards.
Model Overview
| Model | System role | Primary measurements | Standards / application fit |
|---|---|---|---|
| AFC 132 | Filter-media and small-element test system | Pressure drop, gravimetric efficiency, fractional efficiency and dust holding capacity | General, cabin, intake and high-efficiency filter development and quality assurance |
Key Features
Multi-standard platform
Supports test concepts for general air filters, cabin filters, intake filters and high-efficiency media.
Liquid and solid aerosols
Can generate or use DEHS, paraffin oil, NaCl, PSL and customer-specific test aerosols.
Variable volume-flow range
Alternative measuring sections support different face velocities and specimen types.
Single-instrument sample switching
Upstream, downstream and purge sampling can be switched through a controlled sampling unit.
Flexible system expansion
Modular Topas components allow later changes in aerosol generation, dilution and particle measurement.
AFC132Win software
Integrated control and data acquisition support repeatable measurement sequences and reports.
