ESAB PROTEX is the flashback Arrestors designed to eliminate explosion or fire caused by flashback. The flashback Arrestor fits perfectly on regular outlet. It is fitted with a large capacity filter that allows unrestricted fitted flow gas flow during normal operations.
· Incorporates a high capacity flame-arresting element that puts out flame in case of flashback.
· A non-return valve is fitted next to filter. It seals the passage and avoids reverse gas flow and opens again when the pressure of reverse gas-flow is reduced.
· A thermo-sensitive cut-off valve cuts off gas before reaching ignition temperature to eliminate incidence of fire.
· There is also a “Shock-Wave” activated cut-off to stop gas flow through arrestor. The valve closes when pressure drops to 1.5 bar. Hence, even during powerful flashback, explosions in hose are eliminated.
· The safety-reset button is “fail sate” and cannot be made operative by tying down.
