AtlasIED MLE-1 Explosion-Proof Compression Driver – 30W

The AtlasIED MLE-1 is a heavy-duty 30-watt explosion-proof compression driver designed for voice paging, public address announcements, and electronic signaling in hazardous industrial environments. Engineered for use with compatible AtlasIED explosion-proof horn assemblies, the MLE-1 provides high-efficiency sound reproduction in facilities where conventional paging equipment may not be suitable.

Built with a rugged die-cast aluminum housing, the MLE-1 is designed for demanding industrial applications involving potentially hazardous atmospheres. Its high-intelligibility driver provides a specified 300Hz–14kHz frequency response, supporting clear voice announcements and audible signaling.

When paired with the appropriate AtlasIED horn, the MLE-1 provides high sound pressure levels for industrial paging and notification systems. The driver delivers a specified sensitivity of 107dB with the HLE/MLE-30 horn or 110dB with the HLE/MLE-32 horn.

The MLE-1 features an 8-ohm connection, a continuous power rating of 30 watts, and a durable construction intended for specialized industrial communication installations.

Important: The AtlasIED MLE-1 is a compression driver only. A compatible horn assembly is required and must be selected separately. Only the AtlasIED HLE/MLE-30 and HLE/MLE-32 horns are identified by the manufacturer as UL Listed for use with the HLE/MLE explosion-proof driver series.

Designed for Hazardous Industrial Environments

The AtlasIED MLE-1 is intended for professional paging and signaling applications where hazardous-location-rated equipment is required.

Its explosion-proof construction makes it suitable for consideration in appropriately classified industrial environments, subject to the exact equipment certification and installation requirements.

Potential applications include industrial processing facilities, manufacturing operations, chemical facilities, and other locations requiring specialized communication equipment.

The MLE-1 is designed to reproduce voice announcements and electronic signals as part of a professionally engineered industrial communication system.

Installation Note: Hazardous-location suitability must be confirmed against the equipment's actual certification markings, the site's hazardous-area classification, and applicable electrical codes.

High-Output Voice and Signal Reproduction

The MLE-1 features a 30-watt continuous-duty compression driver designed to provide efficient audio output when used with a compatible horn.

Its 300Hz–14kHz frequency response supports speech reproduction and electronic signaling.

The driver is designed to work with AtlasIED horn assemblies that provide different acoustic coverage characteristics.

Specified sensitivity varies according to the selected horn:

With AtlasIED HLE/MLE-30 Horn

• Sensitivity: 107dB
• Compatible with the MLE-1 compression driver
• Final dispersion and dimensions depend on the horn assembly

With AtlasIED HLE/MLE-32 Horn

• Sensitivity: 110dB
• Compatible with the MLE-1 compression driver
• Final dispersion and dimensions depend on the horn assembly

These configurations allow system designers to select a horn based on the required coverage and output characteristics.

Rugged Die-Cast Aluminum Construction

The AtlasIED MLE-1 incorporates a durable die-cast aluminum housing intended for demanding industrial installations.

Its construction supports use in environments where mechanical durability and specialized equipment protection are important.

The driver assembly includes ½-inch conduit access for wiring connections and an adjustable mounting arrangement as described in the supplied product information.

Installation must follow the manufacturer's instructions and the requirements of the hazardous-location classification.
