Air Intake Filter Test System SC-5011

Test Overview

It is used to evaluate the performance of air intake filters . Below are the key test parameters:

1. Restriction and Differential Pressure Test

· Test Purpose: Measures resistance variations at different airflow rates to plot the resistance-airflow curve.

· Test Method:

o Select five flow rate points between 50% and 150% of the rated flow.

o Record the pressure drop (ΔP) at different flow rates.

· Application: Evaluates airflow capacity and ensures the filter does not excessively restrict engine intake.

2. Initial Efficiency

· Test Purpose: Determines the filter’s efficiency in capturing particles at the start of operation. 

· Test Method:

o Uses A4 Fine (fine dust) or A2 Coarse (coarse dust) for testing.

o Adds either 20g of dust or a mass equivalent to six times the flow rate (m³/min) (whichever is greater).

o Weighs the test filter and absolute filter increment, calculating initial efficiency (%).

· Application: Evaluates the initial filtration capability of new filters.

3. Full-Life Efficiency

· Test Purpose: Measures overall filtration efficiency when the filter reaches its final restriction.

· Test Method:

o Dust is continuously introduced until the filter reaches its final pressure drop (e .g., 250 mmH₂O or 2.5 kPa).

o Measures cumulative filtration efficiency over the entire test.

· Application: Provides insight into the filter’s performance over its lifespan.

4. Incremental Efficiency

· Test Purpose: Evaluates filtration efficiency at different loading stages before reaching the final restriction.

· Test Method:

o Efficiency is measured at 10%, 25%, and 50% of the difference between final and initial pressure drop.

o Weighs the test filter and absolute filter, calculating efficiency at each stage.

· Application: Assesses how filtration efficiency changes over time.

5. Dust Holding Capacity Test

· Test Purpose: Measures the total dust mass retained in the filter when it reaches its final restriction.

· Test Method:

o Records the total weight difference of the filter before and after the test to determine its dust holding capacity.

o The test stops when the rated final restriction (e.g., 2.5 kPa) is reached.

· Application: Determines filter longevity and replacement intervals.
