Process flame arrestors for flameproof enclosures:
A flame arrestor is a safety device purposed to prevent flame propagation inside process lines of a system to avoid an ignition. It provides connection of tubing systems for electro/pneumatic and gas/liquid analysis devices through the wall of the explosionproof enclosure.
Pressure switches, moisture analyzers and gas analyzers are typical applications where these flame arrestors are used.
The FT-Cross flame arrestor has an improved flame path which allows more flow and/or lower pressure drop compared to the normal FT series.
