Air-Emulsion Fire Extinguishers (OVE): Efficiency, Features, and Usage
At safsale.com, we explore the most advanced and efficient fire safety tools available—air-emulsion fire extinguishers. Renowned for their safety and effectiveness, these devices offer superior fire suppression with minimal collateral damage.
What Are Air-Emulsion Fire Extinguishers?
Air-emulsion fire extinguishers (OVE) combine water-based solutions with air to create a fine mist or emulsion that suppresses flames effectively. This innovative approach ensures rapid cooling and oxygen displacement, making them ideal for a wide range of applications.
Structure and Functionality
Each OVE extinguisher includes:
- Durable Steel Cylinder: Anti-corrosion coatings inside and out.
- Pressure System: Operates with consistent internal pressure.
- Discharge Mechanism: Features a lever-operated ZPU with a siphon tube.
- Safety Features: Includes a pressure gauge, safety pin, and tamper-proof seal.
The extinguishing agent, mixed with surfactants and optional anti-freeze compounds, is dispensed through a precision nozzle, forming a high-adherence film over fire sources.
Applications and Benefits
Primary Use Cases:
- Effective against Class A fires (solids like wood, paper).
- Suitable for Class B fires (flammable liquids).
Advantages:
- Safe for indoor use without respiratory hazards.
- Reduces the risk of re-ignition with a non-corrosive, easy-to-clean film.
- Usable in environments with people present, such as schools and public transit.
Special Considerations:
- Limited use for Class C fires (flammable gases) only with certified models.
- Not suitable for reactive metals like sodium or materials burning without oxygen.
Key Features
- Efficiency: Covers up to 70 square meters with a discharge range of 3+ meters.
- Longevity: Operates for 10 seconds or longer, with up to 40 uses before replacement.
- Temperature Range: Functions reliably between -40°C and +50°C, making it versatile for varied climates.
Why Choose Air-Emulsion Extinguishers?
While slightly more expensive than traditional models, their safety, efficiency, and reduced secondary damage make them a superior choice for fire safety. Compared to foam or powder extinguishers, a 5-liter OVE matches the performance of a 50-liter powder unit or a 100-liter foam unit in Class A scenarios.
Maintenance and Environmental Impact
OVE extinguishers require less frequent maintenance:
- Refills Every 10 Years: Versus annual checks for traditional units.
- Eco-Friendly: Emulsion dissipates naturally without harmful residues.
These features make them an optimal choice for schools, offices, warehouses, and transport systems.
