Guardian Precoat is a conditioner for new dust collection baghouse bags. Any time new bags are introduced into a baghouse, they should be precoated with a conditioner. Guardian Precoat is a superior precoat option introduced into the ductwork after new bags are installed in the baghouse. Guardian Precoat will coat and condition the bags to allow for a more efficient operation and longer bag life. Guardian Precoat Conditioner is made from an engineered blend of low-density, porous, amorphous silica powder (perlite). Guardian Precoat creates a protective and absorbent dust cake. It absorbs hydrocarbons and moisture and protects against blinding and plugging. Guarding Precoat will improve your filter life and performance.
