About Cashco – 7A00 Detonation Flame Arrestor

The Cashco 7A00 detonation flame arrestor is a device that can be fitted to the opening of an enclosure or to the connecting pipe work of a system of enclosures. Its primary function is to allow the flow of gases or vapor of flammable liquids through the enclosure, but prevent the  transmission of a flame.

The element inside the housing provides an extinguishing barrier to the ignited vapor mixture by absorbing heat from the flame. The Model 7A00 is used as an independent safety system to ensure explosion protection.

We have full valve repair and reconditioning facilities in Secunda & Durban.
