Flame arrestors
Flame arrestors are safety devices for reliable protection against hazardous flame flash-back in gas supply systems.
Safety Devices – F53N-ES and F53N/H-ESAV619 Series
The F53N-ES and F53N/H-ES Series safety devices provide protection against flame flash-back and extinguish flame blow-backs in gas supply systems. They are employed in gas supply systems with corrosive gases, such as fuel gas or oxygen, in the chemical industry, in the laboratory sector or in process technology. The devices can be installed in any position. The ambient temperature must not exceed 70°C.
The F53N-ES and F53N/H-ES Series safety devices are designed without check valve for minimum working pressures upline and downline of analysis devices.
F53N-ES and F53N/H-ES Series safety devices extinguish hazardous flame flash-backs by means of flame arrestors (FA) of sintered chrome-nickel steel. The temperature-controlled cut-off valve (TV) extinguishes flame blow-backs.
