PURGEnVENT Model 7950 Automatic Inline Air Vent (ILV)

Automatic Air Venting for Corrosion Protection in Fire Sprinkler Systems

AGF’s PURGEnVENT Model 7950 Automatic Inline Air Vent is designed to help prevent corrosion in wet fire sprinkler systems by efficiently removing trapped air. Built with a specialized separation chamber and integrated air scoop, the 7950 ILV promotes the effective separation of air from water as the system fills. The separated air is automatically released through the patented Model 7900 AAV Automatic Air Vent, which is included in the assembly, helping to extend the life of the system and minimize maintenance needs.

Manufactured with quality and compliance in mind, the Model 7950 ILV meets the requirements of the Build America, Buy America Act (BABAA), making it suitable for use in federally funded projects.

Integrated Components for Enhanced Functionality

• FM Approved and UL Listed 7900V Automatic Air Vent – Ensures reliable air release to mitigate corrosion.
• Built-in Isolation Valve and Strainer – Provides system protection and allows for easy maintenance.
• Purge Valve with Union and Hose Connection – This speeds up air removal during filling, facilitates strainer flushing and cleaning, and functions as a vacuum breaker to improve system drainage while preventing gasket displacement.
• BABAA-Compliant Domestic Components – Includes domestically manufactured couplings and end cap with fittings to meet current federal requirements.

Key Advantages of the 7900V Air Vent:

• Conical Shape – Maximizes clearance and shields the venting valve from contamination and moisture.
• Recessed Design – Protects the vent from damage and prevents the need for vent redundancy.
• Single-Float Mechanism – Allows only vertical movement for precise operation.
• Bubble Breaker – Enhances air passage and acts as a secondary filtration layer.

Specifications:

• NFPA 13 Compliant / BABAA Compliant
• FM Approved & UL Listed 7900V Air Vent
• 175 PSI Rated
• System Drain Vacuum Break for Faster Drainage
• Inline Speration Chamber with Air Scoop

Recommended Installation:

The 7950 ILV is ideal for installation directly after the floor control assembly, providing reliable air elimination at a key point in the system layout. For added installation flexibility, the separation chamber can be rotated 45 degrees to accommodate spatial constraints; however, the air vent must remain in a vertical position to function properly.
