Panel Sheet: Perforation Diameter 1.5-5.0 mm

Component Specifications

Definition

A precision-engineered sheet component with uniform perforations, designed as part of a perforated diffuser panel system to regulate airflow, reduce turbulence, and ensure even air distribution in industrial ventilation and air handling applications.

Working Principle

Operates on the principle of pressure equalization and laminar flow control. Air passes through precisely sized perforations, converting high-velocity turbulent air into low-velocity laminar flow, ensuring uniform distribution while minimizing noise and pressure drop.

Materials

Typically manufactured from cold-rolled steel (CRS), aluminum alloys (e.g., 3003-H14), or stainless steel (e.g., 304/316), with corrosion-resistant coatings (e.g., powder coating, galvanization) for durability in various environments.
