Test Principle
Dust Loading Test: Measures differential pressure changes under dust load to determine operational capacity.
Gravimetric and Fractional Efficiency: Assesses filter performance using gravimetric and particle-size-dependent separation efficiency.
Loading Capacity: Determines maximum dust holding capacity for long-term stability.
Cyclic Aging Test: Measures performance after repeated loading and cleaning cycles to evaluate durability.
