Frazier Air Permeability - Universal Specimen Holder - FAP-USH-1

The Universal Specimen Holder FAP-USH-1 is an add-on accessory for the Frazier Differential Pressure Permeability Instrument that is used to increase the instrument’s versatility in checking the permeability of depth type materials. The FAP-USH-1 is one version of the Universal Specimen Holder (FAP-USH) that easily adds on to the Frazier Air Permeability Tester to test samples up to 1 inch (25 mm) in thickness. Samples can be quickly loaded and unloaded easily into unit. This holder will accept different shape samples with a parallel top and bottom up to 1" thick. Custom inserts that are the same thickness and shape as the specimen to be tested are used to hold the sample in position and seal tightly on the sample to eliminate edge leakage while avoiding compression of sample. Samples must fit into a 4" dia circle. The standard minimum sample size is 1.128" dia (1 sq in). Smaller custom sample sizes down to about 0.75" dia are available.
