In-Line Deflagration Flame Arresters, ATEX / CE / ISO

Series No. 45000E / 46000E

Gas Groups:
45000E – IIA | D
46000E – IIA, IIB3 | D, C 

Protectoseal Series 45000E and 46000E In-Line Deflagration Flame Arresters are designed to withstand low, medium and high pressure deflagrations (subsonic). These arresters are bi-directional and capable of stopping a flame approaching from either direction in a piping system and can be mounted vertically or horizontally in the pipeline. Suitable for varying distances from the unprotected side of the vent pipe, maximum distance (Lu/D=50), and within determined operating pressure, consult factory for specifics. These arresters prevent confined deflagrations from passing the arrester and entering a protected area. 

 

Description
