Product Description

Environmentally responsible Knockdown®, Class A foam concentrate from National Foam, is a unique formulation providing unmatched firefighting performance and flexibility. Knockdown is specially designed for use in Class A/B foam systems and is excellent for Compressed Air Foam Systems (CAFS).

Knockdown works in two ways. First, it improves the penetrating capability of water. It reduces the surface tension of plain water which allows it to penetrate surfaces where water might normally run off, to reach deep-seated fires. This helps reduce the amount of water required to extinguish the fire and also provides quicker knockdown.

Secondly, Knockdown increases the heat absorbing capabilities of water. Foaming ingredients give water the ability to adhere to vertical surfaces which allows the water longer contact with the fuel. The longer the water is in contact with the fuel, the more heat it is able to absorb. A coating of Class A foam may also be used for exposure protection to prevent fuels from igniting by raising their moisture content and providing a tough protective barrier to an oncoming flame front.
