1 In-Line Deflgrtion Flme Arrester eccentric design, bidirectionl d dismntling dimension for servicing (temerture sensor) Design with one or two temerture sensors b Ø c The stndrd design will work t n oerting temerture of u to +60 C / 140 F nd n oerting ressure (bs.) u to 1.1 br / si. Devices with secil rovls cn be obtined for higher temertures nd ressures. Tye-roved ccording to ATEX Directive 94/9/EC nd EN s well s other interntionl stndrds.

Due to its eccentric design the device cn be instlled in ielines tht run close to fl oors or wlls nd low oints, where condenste cn collect within the iing system, cn be voided. When instlling the defl grtion fl me rrester, mke sure tht the distnce between otentil ignition sources nd the loction of the instlled device, does not exceed the L/D rtio (ie length/ie dimeter), for which the device ws roved. According to EN the instlltion limits re L/D mx 50 for defl grtion flme rresters of exlosion grous IIA nd IIB3 (NEC grous C to D) nd L/D mx 30 for exlosion grou IIC (NEC grou B). The defl grtion fl me rrester is symmetricl nd offers bidirectionl fl me trnsmission rotection. The device consists of two housing rts (1) nd PROTEGO fl me rrester unit (2) in the center. The fl me rrester unit is modulr, consisting of severl FLAMEFILTER (3) instlled within the FLAMEFILTER cge. The number of FLAMEFILTER nd their g size deend on the devices intended use. Providing the oerting conditions such s the temerture, ressure, exlosion grou nd the comosition of the fl uid, enbles PROTEGO to select the best defl grtion fl me rrester for your liction. The FA-E series of defl grtion fl me rresters is vilble for substnces from exlosion grous IIA to IIC (NEC grous B to D). Design nd Secifictions There re three different designs: Bsic defl grtion fl me rrester design Defl grtion fl me rrester with integrted temerture sensor* for dditionl rotection ginst short-time burning from one side Defl grtion fl me rrester with two integrted temerture sensors* for dditionl rotection ginst short-time burning from one side Additionl secil devices vilble uon request *Resistnce temerture sensor for equiment grou II, ctegory (1) 2 FA-E - - FA-E - T - FA-E - T - B All rights nd ltertions reserved cc.
