WITT FLASHBACK ARRESTOR HAS HIGHER PERFORMANCE USING A PARALLEL CONNECTION

85-10 Flashback arrestors from Witt, the gas safety, control, mixing and analysis equipment supplier when connected together in parallel give users the opportunity to use a higher gas flow rate as well as a lower cost alternative to using an 85-30 flashback arrestor. Witt EN 730/ISO 5175-1 standard 85-10 flashback arrestors are BAM certified and used with shielding gases in welding as well as in foundries and steel making protecting gas cylinders and gas supply hose outlet points against gas back feeding and flashbacks. By using 2 x parallel connection tee-pieces supplied by Witt, two of these flashback arrestors can be connected together in parallel to supply an increased flow rate of up to 64%. It is also a simple, economical yet safe option to using a 85-30 flash back arrestor. This option can be used as both a temporary or permanent installation. They can be mounted in any orientation and provide triple protection against gas back feeding and flashbacks with their built-in flame arrestor, thermal cut off valve and non return valve. It is recommended for safe working of flashback arrestors that the non-return valve, body leak tightness and flow capacity is checked and serviced annually by the manufacturer, however the dirt filters can be replaced by trained staff.
