Precoating powder is a chemically inert powder used to protect industrial dust filters from fine, sticky or difficult-to-release dust particles. For information about applications, consumption rates or pricing, please contact us.
Precoating is commonly used in applications such as:
The powder is applied to the filter media before the system is started up and forms a protective layer between the filter media and the dust.
During filtration, a dust layer or filter cake forms on the surface of the filter. With certain dust types, this filter cake can adhere strongly to the filter media, causing premature filter blockage and making cleaning more difficult.
Precoating powder creates a temporary protective layer on the filter surface. As a result, dust particles attach primarily to the precoating layer rather than directly to the filter media.
This provides several benefits:
Lime is often used as a precoating material. However, our precoating powder offers several advantages:
As a result, the protective layer remains active for longer, helping to extend the service life of filter sleeves, filter bags and other industrial dust filters.
The required consumption depends on the filter area, filter type and application.
As a general guideline, a consumption rate of approximately 40 to 70 g/m² of filter area is recommended.
The exact quantity depends on the dust characteristics, the filter surface area and the properties of the filter media.
For specific applications, we are happy to advise on the correct dosage and application method.
