E2S STExL2F Explosion Proof Loud-Speakers

E2S STExL2F Explosion Proof Loud-Speakers

 

E2S STExL2F Explosion Proof Loud-Speakers for Hazardous Area Signalling Applications

The STExL2F are high output, 119dB(A) PA Explosion Proof Loud-Speakers with a re-entrant flare horn. The high output driver in a robust IP66 corrosion proof 316L stainless steel enclosure ensure the STExL2F is suitable for all Zone 1, 2, 21 & 22 explosion proof applications. Available with 70 or 100V line transformer or as low impedance versions, all models have triple cable entries, and large termination areas. The termination chamber and cover feature a threaded flameproof joint simplifying both installation and routine maintenance.
