Products Description
Air Aspirating Foam Nozzle
Air aspirating foam nozzle is a specialized firefighting nozzle designed to mix foam concentrate with water and air to produce finished foam for fire suppression. These nozzles are particularly effective against Class A (ordinary combustibles) and Class B (flammable liquids) fires.
These nozzles draw in ambient air (aspiration) as the foam solution (water + foam concentrate) flows through them. The air mixes with the solution to create a finished foam that expands and is applied to the fire. Produces high-quality, expanded foam with good bubble structure.
Types of Foams Used:
Primarily used with AFFF (Aqueous Film Forming Foam) and protein-based foams. Also effective with Class A foams used in wildland and structural firefighting.
Applications: Petrochemical facilities. Aircraft rescue and firefighting (ARFF). Fuel storage tanks. Warehouses with flammable liquids

FAQ
Q: What is an air aspirating foam nozzle?
An air aspirating foam nozzle is a firefighting device designed to mix foam concentrate with water and air to produce an expanded foam for fire suppression, particularly effective on flammable liquid fires (Class B).
Q: How does air aspirating foam nozzle work?
The nozzle uses the Venturi principle to draw in ambient air as foam solution (water + foam concentrate) flows through it. The mixture of water, foam concentrate, and air creates a finished foam that blankets the fuel surface to suppress vapors and cool the fire.
Q: What types of foam are compatible with air aspirating foam nozzles?
Air aspirating foam nozzles are typically used with:
AFFF (Aqueous Film Forming Foam)
AR-AFFF (Alcohol Resistant AFFF)
Protein-based foams
Fluoroprotein foams
Q: Can air aspirating foam nozzle be used with portable and fixed systems?
Produces more higher-expansion foam
Effective vapor suppression
Excellent burnback resistance
Reduced water usage compared to water-only nozzles
Q: How does air aspirating foam nozzle work?
Yes. Air aspirating foam nozzles can be integrated into both portable units (e.g., fire hoses) and fixed suppression systems.
