Maintenance Powder
Prestart Powder
 Prestart Powder is used as an initial control layer on the filter
bags. It also helps in the release of the dustcake during the cleaning
cycle, improves initial efficiencies and protects the bags during
critical initial startup after rebagging.
Prestart powder is packaged in 50 lb. bags. (Covers 1,000 sq. ft.
of cloth)
Formula for prestart powder
Dia. 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.
 Leak Detection Powder
Leak detection powder is an aid in finding thosetroublesome
leaks in your baghouse. By injecting the leak detecting powder into
the baghouse inlet, the powder will travel throughout your baghouse.
By using a backlight, the leaking area shows up as a bright colored
powder marking.
 Packaged 4-1 gal. cans, 25 gal. pail or 55 gal. drum.
