组件规格

定义
A precision-engineered structural component that provides rigid support and airtight sealing for perforated diffuser panels in industrial air distribution systems. It ensures proper panel alignment, prevents air leakage, and maintains consistent airflow patterns through the perforated surface.
工作原理
The frame provides structural integrity and mounting points for the perforated panel, while the seal creates an airtight barrier between the panel and ductwork. This prevents bypass airflow, ensures uniform air distribution through the perforations, and maintains system pressure integrity.
材料
Galvanized steel (frame)EPDM rubber or silicone foam (seal)powder-coated finish for corrosion resistance
Fire Rating
Class A (non-combustible)
Frame Thickness
1.2-2.0 mm
Pressure Rating
Up to 500 Pa
Frame Dimensions
Customizable to panel size
Seal Compression
30-40%
Operating Temperature
-20°C to 120°C
标准
ISO 5167DIN 24194ASHRAE 62.1

常见问题

What is the purpose of the seal in a perforated diffuser frame?

The seal prevents air leakage between the diffuser panel and ductwork, ensuring all air passes through the perforations for controlled distribution and maintaining system efficiency.

Can frame/seal components be customized for different panel sizes?

Yes, industrial frames and seals are typically custom-engineered to match specific perforated panel dimensions and mounting requirements.

How often should diffuser seals be inspected?

Seals should be inspected annually during routine HVAC maintenance. Replacement is recommended when compression loss exceeds 50% or visible degradation occurs.
