Filter Mounting Frame: Flatness Tolerance ≤0.5 mm/m

Component Specifications

Definition

A rigid structural component designed to provide precise mounting, alignment, and support for filtration media within industrial filtration systems. It ensures proper sealing, maintains filter positioning under operational pressures, and facilitates maintenance access while withstanding mechanical stresses and environmental conditions.

Working Principle

Provides mechanical support and precise positioning for filtration elements through a rigid frame structure that distributes loads evenly, maintains alignment tolerances, and interfaces with the machine's filtration section housing. The frame typically incorporates mounting points, sealing surfaces, and alignment features to ensure optimal filter performance and prevent bypass leakage.

Materials

Typically constructed from corrosion-resistant materials: stainless steel (AISI 304/316), powder-coated carbon steel, or aluminum alloys (6061-T6). Gaskets/seals often use EPDM, silicone, or Viton for chemical resistance.

Frequently Asked Questions

What are the critical tolerances for filter mounting frames?

Flatness (≤0.5 mm/m) and parallelism of mounting surfaces are most critical to prevent filter bypass and ensure proper sealing. Alignment holes typically require ±0.1 mm positional tolerance.

Can filter mounting frames be customized for different filter types?

Yes, frames are often custom-designed for specific filter cartridges, bags, or panels, with variations in mounting mechanisms, sealing methods, and dimensional requirements.

How does material selection affect frame performance?

Stainless steel offers best corrosion resistance for harsh environments, aluminum provides lightweight strength, while coated carbon steel balances cost and durability for standard applications.
