MEDC DB3 Sounder (up to 118 dB(A)) with 27 output tones, Weatherproof only, IP66 and IP67, designed to be used on potentially explosive gas and dust atmospheres. -55C to +70C. *** Phased Out *** Replaced by DB3B

Inquiry

This range of light weight all GRP, flameproof sounders is intended for use in potentially explosive gas and dust atmospheres and has been designed with high ingress protection to cope with the harsh environmental conditions found offshore and onshore in the oil, gas and petrochemical industries.

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.

An optional Exe terminal chamber is available.

An uncertified version is available for use in non-explosive atmospheres.
