Flash Back Arrestor High Flow - Reg Mount 3/8 BSP

High Flow Regulator Mounter 3 Function Flash Back Arrestor - Multiple Use. Special purpose high flow flashback arrestors stocked with G3/8 connections but are available with G1/2 connections if required. (Flow capacity is the same). Our German manufactured FBAs have 3 functions:- "FA" Flame Arrestor - The first is the flame quenching element which is of course a sintered metal filter which absorbs the heat from a flashback (when the conditions are within the design parameters) "NV" Non Return Valve - The second function is that these regulator mounted FBA incorporate a non-return valve to prevent the back feeding of gases, the primary cause of flashbacks. "TV" The third and final element to this flashback arrestor is the thermal cut off valve which is activated by heat. This thermal trip is a final fail safe designed to cut the incoming gas supply off permanently. The thermally activated cut off valve is not and will not be triggered by experiencing a flash back alone. An external fire or an internal fire would cause the valve to close, helping to prevent further damage. These flashback arrestors may be used continually even when having suffered many flashbacks, these flashback arrestors do not require resetting. Should you be unfortunate and experience a flashback then it is important to investigate why so you may prevent any future problems from occurring. The primary cause for the majority of flashbacks will be due to incorrect lighting up procedure and failure to purge the gases properly. The second most common cause is lighting up with too low a fuel gas flow combined with a leaking oxygen valve. Therefore - check your gas equipment for - damage - for leaks et cetera before lighting up and then light up correctly. If you need advice please give us a call.
