Precoat new filters for better airflow and longer filter life
When your dust stream contains a significant percentage of submicron particles, precoating can reduce or prevent failure or pre-mature blinding of your new filter media.
Precoating new filters, provides other benefits, too. By keeping particles on the filter surface, precoating improves the dust collector's initial filtering efficiency at startup. Precoated filters are easier to clean and provide better dust cake release. Precoating materials, which don't burn, can be applied to filters made of fire-retardant media to help reduce explosion risks in spark-producing process such as milling, welding, and grinding. >> When to Change Your Filters
