Cooper Wheelock DB4 Range Specification

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.
This product does not include a blocking capacitor. Contact Cooper
Wheelock Technical Support for models with a blocking capacitor*.
