# Industrial Specification: Dampers / Louvers

## 1. Technical Definition
Regulatory airflow control devices within humidity exhaust systems

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-25 m/s airflow velocity, 0-1000 Pa pressure differential**. Failure boundary: **Structural failure at 1500 Pa pressure differential, blade deformation at 35 m/s airflow velocity**, Mechanism: **Aerodynamic flutter instability at Reynolds numbers &gt; 5×10^5 causing harmonic blade vibration exceeding material yield strength (typically 250 MPa for aluminum alloys)**.

### 2.1 Analytical Physics Model
Governed by the **Harmonic Vibration Force Generation**:

> **Primary Equation**: $F_e = m \cdot r \cdot \omega^2 \sin(\omega t)$  
> **Engineering Impact**: Calculates centrifugal force for vibratory sifters/feeders.
