DB4 Range

Description:

This range of loudspeakers, intended for use in potentially explosive

gas and dust atmospheres, has a power rating of up to 25 watts and

is suitable for use in all gas groups including hydrogen.

The ﬂamepaths, ﬂare and the body, are manufactured completely

from a UV stable glass reinforced polyester. Stainless steel screws

and sinter are incorporated thus ensuring a corrosion free product.

A tapered ﬂamepath is used to overcome the problems of assembly

of parallel spigot ﬂamepaths.
