The MEDC DB4 Speaker is designed for use in potentially explosive gas and dusty atmospheres. This MEDC Speaker has a power rating up to 25 watts and is suitable for use in all gas groups including hydrogen.
The flame paths, flare and the body of the MEDC DB4 are manufactured out of UV stable glass reinforced polyester. Stainless steel screws and sinter are incorporated, ensuring a corrosion free product. A tapered flame path is used to overcome problems of assembly of parallel spigot flame paths.
An optional Exe terminal chamber is available. An uncertified version is also available for use in non-explosive atmospheres.
