# Industrial Specification: Suction Fan/Blower

## 1. Technical Definition
A mechanical device that creates airflow to draw dust and particles into a dust collection system

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-2.5 kPa negative pressure differential, 500-3000 m³/h airflow volume**. Failure boundary: **Impeller structural failure at 4500 RPM centrifugal force exceeding 15 kN, bearing seizure at 120°C lubricant temperature**, Mechanism: **Fatigue fracture from cyclic stress exceeding 275 MPa yield strength at blade root, lubricant thermal breakdown at Arrhenius rate constant k=1.2×10⁻⁵ s⁻¹**.

### 2.1 Analytical Physics Model
Governed by the **Darcy-Weisbach Pressure Drop**:

> **Primary Equation**: $\Delta P = f \cdot \frac{L}{D} \cdot \frac{\rho v^2}{2}$  
> **Engineering Impact**: Critical for sizing CIP (Clean-In-Place) pump heads.
