# Industrial Specification: HEPA/ULPA Filter Module

## 1. Technical Definition
A modular filtration unit containing HEPA or ULPA filters that provides sterile air supply and containment within aseptic barrier systems.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-1.0 m/s face velocity, 250-750 Pa pressure differential**. Failure boundary: **1.2 m/s face velocity causing filter media rupture, 1000 Pa pressure differential causing seal failure**, Mechanism: **Darcy's law fluid dynamics exceeding filter media tensile strength (3.5 MPa for HEPA glass fiber), Bernoulli principle creating pressure-induced seal deformation**.

### 2.1 Analytical Physics Model
Governed by the **Hansen Solubility Distance (HSP)**:

> **Primary Equation**: $R_a = \sqrt{4\Delta\delta_d^2 + \Delta\delta_p^2 + \Delta\delta_h^2}$  
> **Engineering Impact**: Predicts seal/gasket swelling when exposed to CIP chemicals.

| Symbol | Variable Definition | Localized Reference |
| :--- | :--- | :--- |
| \delta_d | Dispersive | Engineering Constant |
| \delta_p | Polar | Engineering Constant |
| \delta_h | Hydrogen | Engineering Constant |

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Moisture ingress exceeding 85% RH for 72 hours | 8 | Filter media delamination and microbial growth | Hydrophobic coating (contact angle &gt;110°) with integrated humidity sensors |
| Vibration amplitude exceeding 0.5 mm at 60 Hz | 8 | Gasket seal fatigue and particle bypass | Anti-vibration mounting with natural frequency &gt;100 Hz and damping ratio &gt;0.3 |

## 3. Key Technical Parameters
| Parameter | Value | Unit | Status |

## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What is the difference between HEPA and ULPA filters in these modules?
**A**: HEPA filters capture 99.97% of particles ≥0.3 microns, while ULPA filters capture 99.999% of particles ≥0.12 microns, providing higher purity for critical chemical manufacturing applications.

### Q: How do these filter modules maintain containment in aseptic barrier systems?
**A**: The modules feature polyurethane or silicone gaskets and sealed aluminum/stainless steel frames to prevent air leakage, ensuring sterile air supply and containment within controlled environments.

### Q: What maintenance is required for HEPA/ULPA filter modules in chemical facilities?
**A**: Regular integrity testing, gasket inspection, and filter replacement based on pressure drop monitoring are essential to maintain filtration efficiency and system performance in chemical manufacturing settings.
