Designing a baghouse system requires careful calculation and optimization of multiple design variables to ensure reliable performance, regulatory compliance, and long-term durability.

What Is Precoating Powder?

Precoat powder comes in 50-lb bags.

Precoating powder is a fine, inert material applied to new or cleaned filter bags before they’re used. It forms a protective layer between the bags and the incoming dust.

Importance of Applying Precoating Powder

Precoating improves filter performance by preventing fine, sticky, or oily dust from penetrating and blinding the media. It helps form a stable dust cake and extends bag life. This is especially important in high-moisture or hydrocarbon-heavy environments like asphalt or food processing.

Note: Precoating is effective but must be done correctly. The type of precoating powder, amount applied, and how it’s introduced all matter. Work with a baghouse expert to ensure proper application.
