PERMEABILITY TESTS
Permeability tests can be performed on clean bags, or with process dust on the surface. For pulse jet bags Filter Holdings uses a special apparatus that can simulate pulsing conditions in the baghouse. By comparing permeability before and after cleaning with reference standards, specific process problems may be identified.
WEIGHT ANALYSIS
Weight analysis, before and after cleaning can be a valuable indicator of the level of dust loading and penetration when compared to reference standards.
MULLEN TEST
The Mullen Burst Strength Test is a measure of the two dimensional, or planar, strength of the media, measured in pounds per square inch. The sample is securely clamped over a rubber diaphragm. The diaphragm is steadily pressurized with fluid until it expands to the point where it breaks through the media. The corresponding pressure of the fluid within the diaphragm at the point when the media ruptures is recorded as the strength. The effects on the filter from mechanical, chemical, or thermal stress are determined.
