Products Description
Foam chamber (also called a foam pourer with chamber) is mounted on the tank shell near the top. It introduces a mixture of foam concentrate, water, and air (foam solution) into the tank. The foam solution enters the chamber, expands, and passes through a deflector plate, which gently distributes foam onto the liquid surface.
Air Inlet Screen – allows air induction.
Vapor Seal / Glass Burst Disk – prevents tank vapors from escaping when the chamber is idle.
Deflector Plate – directs foam gently over the liquid or floating roof to avoid agitation.
Foam Generation – ensures proper expansion and stable foam blanket.

FAQ
Q: What is a foam chamber in a storage tank?
A: A foam chamber is a fixed fire protection device installed on storage tanks. It introduces and distributes firefighting foam solution onto the fuel surface inside the tank in case of a fire.
Q: Where is a foam chamber installed on the tank?
A: Typically at the top side shell of the tank, slightly above the liquid/vapor space. For floating roof tanks, they discharge onto the roof or into the rim seal area; for fixed roof tanks, they discharge directly onto the liquid surface.
Q: What is the working principle of a foam chamber?
A: The foam solution enters the chamber, passes through an orifice and air induction device, expands into foam, then exits via a deflector plate that gently spreads the foam onto the liquid surface to blanket and suppress vapors.
Q: What types of foam can be used?
A: Mainly AFFF (Aqueous Film Forming Foam), AR-AFFF (Alcohol Resistant), or protein-based foams depending on the stored liquid.
Q: How is the capacity of a foam chamber determined?
A: Based on the tank diameter, the foam application rate (per NFPA 11 / API standards), and required discharge duration (usually 55–65 L/min·m² for hydrocarbon tanks).
