PRE-GUARD™
Standard Filter Corporation
Prestart Powder
PRE-GUARD™ (Prestart Powder) is used as an initial control layer on the filter bags. It also helps in the release of the dust cake during the cleaning cycle, improves initial efficiencies and protects the bags during critical initial startup after rebagging.
Prestart powder is packaged in 34 lb. bags. (Covers 680 sq. ft. of cloth)
Formula for prestart powder
Diameter. of bag in inches X 3.14 X length of bag in inches X quantity of bags divided by 144 = total sq. ft. of filter cloth area. Since 1 lb. of prestart powder per 20 sq. ft. of filter cloth is required, then divide total sq. ft. by 20 to give you the total amount of pounds required for test.
