WITT RF Flashback Arrestors – Reliable Protection Against Reverse Gas Flow and Flashbacks

WITT RF Flashback Arrestors provide reliable protection against dangerous reverse gas flow and flashbacks, fully tested in accordance with DIN EN ISO 5175-1. Every unit undergoes 100% quality control to ensure safety.

Why choose WITT RF Flashback Arrestors:

• Stainless steel flame arrestor (FA): Large surface area design stops any dangerous flashback entering the device from any direction.
• Temperature-sensitive cut-off valve (TV): Extinguishes sustained flashbacks well before internal temperatures reach hazardous levels.
• Spring-loaded non-return valve (NV): Prevents slow or sudden reverse gas flow from creating explosive mixtures in the gas supply.
• Inlet filter: Protects the arrestor from contamination, extending its service life.

Operation / Usage:
