# Industrial Specification: Dampers

## 1. Technical Definition
A device used to regulate or control airflow within a ducting system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0-1000 Pa differential pressure, -40°C to 120°C ambient temperature**. Failure boundary: **Structural failure at 1500 Pa differential pressure, actuator failure at 85°C continuous operation**, Mechanism: **Material yield strength exceeded at 1500 Pa (using ASTM A36 steel with 250 MPa yield strength), thermal degradation of actuator polymer seals above 85°C (glass transition temperature of EPDM rubber)**.

### 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.
