Air Filtration Performance Test System
Category：Filter Cartridge Filtration Tester
Introduction
1. Application Scenarios
The Air Filtration Performance Test System is designed for performance evaluation of various air filters, including:
Panel Filters
V-Bank Filters
Filter Bags
Cylinder Filters
Ideal for filter manufacturers, research institutions, and quality control laboratories, the system measures key performance indicators such as filtration efficiency, pressure drop, and dust holding capacity.
With optional dust generators and feeders, the system supports:
Dust holding capacity tests
Arrestance (gravimetric efficiency) vs. dust load
Resistance vs. dust load
Efficiency @ 0.4 μm vs. dust load
Fractional efficiency vs. final resistance
2. Compliant Standards
The system is compatible with international and industry standards for air filter performance testing. It is suitable for high-efficiency and medium-efficiency filters, including:
EN Standards
ISO Standards
ASHRAE Standards
Measurable parameters include:
Overall efficiency @ 0.3 μm, 0.5 μm, ePM1.0, ePM2.5
Pressure drop vs. airflow curve
Dust holding capacity
Arrestance vs. dust load
Resistance vs. dust load
Fractional efficiency vs. final resistance
