5/24/10 (new) .20” wg. .20” wg. wg. 9/25/10 .24” .44” wg Pressure drop tests 30/30 - Measurements showed a slow and relatively small increase in pressure less than a 20% increase. Field measurements indicate that the AAF Perfect pleat had a significant increase. The filter more than doubled in resistance in 90 days. Visual Observations Camfil Farr 30/30 Visual inspection revealed that the 30/30 is remaining rigid in the holding frames. Dirt and contaminants are accumulating evenly across the entire pleat surface. Visual inspection indicates that after 14 weeks of service, the 30/30 is rigid and is clearly maintaining filtration capability. Camfil Farr is confident that no other filter in the industry would perform and load like the 30/30 Air Entering Side 30/30 Air Leaving Side 30/30
