# Industrial Specification: Gas Flushing Unit / Vacuum Pump

## 1. Technical Definition
A combined unit that removes oxygen from beverage containers by first evacuating air and then flushing with inert gas to prevent oxidation and extend shelf life.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.1-1.0 bar absolute pressure, 5-20 m³/h gas flow rate, 15-25°C operating temperature**. Failure boundary: **Vacuum pump failure at 0.08 bar absolute pressure (80 mbar) due to insufficient differential pressure for effective gas removal, or at 30°C due to lubricant viscosity breakdown**, Mechanism: **Cavitation in vacuum pump at vapor pressure of water (0.023 bar at 20°C) causing impeller erosion, or gas permeation through container walls following Fick's law (D=1.5×10⁻¹⁰ m²/s for O₂ in PET) when residual oxygen exceeds 0.5%**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Particulate contamination exceeding 10 μm in gas stream | 8 | Seal abrasion leading to 0.1 bar/min vacuum loss | Install 5 μm absolute rated particulate filter with differential pressure monitoring |
| Condensate accumulation in vacuum line reaching 100 mL | 8 | Water hammer pressure surge of 15 bar damaging pump diaphragm | Integrate condensate trap with 80 mL capacity and automatic drain valve |

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

### Q: How does this gas flushing unit prevent beverage oxidation?
**A**: The unit first evacuates air (oxygen) from containers using the vacuum pump, then flushes with inert gas like nitrogen to create an oxygen-free environment that prevents oxidation and extends shelf life.

### Q: What materials make this unit suitable for food/beverage applications?
**A**: Constructed with 316L stainless steel (corrosion-resistant), food-grade elastomers (safe for contact), and aluminum alloy, ensuring hygiene, durability, and compliance with food safety standards.

### Q: What are the key specifications for production efficiency?
**A**: Key specs include cycle time (seconds per container), gas flow rate (L/min), power consumption (kW), and ultimate vacuum level (mbar), which together determine throughput and preservation effectiveness.

## 6. Manufacturing Compliance
- ISO 8573-1:2010 (COMPRESSED AIR PURITY CLASSES)
- CE MARKING (EU MACHINERY DIRECTIVE 2006/42/EC)
