Bogen GA-MLE3-E32 Specsheet

• Explosion-proof loudspeaker for signal and communications systems

• Internally mounted, factory-installed transformer

• 30-watt high-intelligibility driver in cast aluminum housing

• Efficiency of reflex-style projectors with wide angle or circular sound dispersion

Bogen Model GA-MLE3-E32 is used to designate the Atlas Sound®explosion-proof compression driver/horn assembly Models MLE-3T and MLE-32 when specifying and ordering through Bogen. These assemblies are engineered for high-efficiency voice and electronic signal communication in hazardous areas. Drivers, which are protected within a rugged die-cast aluminum housing, have 30-watt power handling, and are equipped with 1/2” conduit access and an adjustable mounting bracket. The spun aluminum bell provides a 95-degree circular distribution emphasis.

Install this loudspeaker to efficiently and safely communicate in combustible and dust-filled areas. Driver complies with the regulations governing electrical equipment at hazardous locations as set forth by the National Electric Code. Driver listed by UL.
