AFC 131 Cleanable Filter Media Test System
Compact laboratory system for characterising cleanable filter media according to VDI 3926-2, with automated dust loading, pressure-drop monitoring, separation-efficiency measurement and pulse-cleaning cycles.
Model Overview
| Model | System role | Primary measurements | Standards / application fit |
|---|---|---|---|
| AFC 131 | Cleanable filter-media test system | Dust loading, differential pressure, fractional efficiency and cleaning-cycle behaviour | VDI 3926-2 and small-scale comparative filter-media testing |
Key Features
VDI 3926-2 workflow
Designed for standardised testing of cleanable filter media using defined dust-loading and cleaning cycles.
Long automated runs
Automated procedures can operate for extended test periods with limited operator intervention.
Solid and droplet aerosols
Supports Pural test dusts and DEHS for different filter-media characterisation tasks.
Pulse-cleaning control
Adjustable pressure-pulse duration and tank pressure support cyclic ageing studies.
Flexible laboratory platform
The compact system can be adapted for additional small-scale filter-media methods.
PAFWin control software
Computer-controlled operation supports sequence execution, data acquisition and reporting.
