DB16
This range of loudspeakers, intended for use in potentially explosive gas and dust atmospheres, has a power rating of up to 30 Watts and is suitable for use in the harsh environmental conditions found offshore and onshore in the oil, gas and petrochemical industries.
With an integral increased safety chamber, for termination, this unit offers both high output and easy installation.
In addition, the 25 Watt version still offers superior output with a higher ambient certified temperature (+65°C).
The flamepaths, flare and body, are manufactured from a UV stable glass reinforced polyester. Stainless steel screws and mounting stirrup are incorporated to ensure a corrosion-free product.
