is pleased to announce that the DB4B, a high quality explosion proof loudspeaker, has now been further developed to include a wider range of certification. In addition to existing ATEX, IECEx, cULus, CUTR, CQST and Inmetro certifications, DB4B has confirmed that it includes Inmetro, DNV, CCOE and SIL2 and expands its wide applications in the oil and gas industry.

Manufactured from GRP Ex enclosure and durable thermoplastic glare, DB4B offers a product that is both corrosion resistant and aesthetically pleasing. The specific SPL figure for sensitivity (1W @ 1m) is 110dB at 1d, and the reserved power for a 25W unit produces 124dB, a 15W unit produces 122dB and an 8W unit produces 120dB. With 8W and 15W units producing enough SPL to meet most specifications, end users can install units with lower power consumption, thus reducing the amount of application and support equipment required. (Please note all SPL ratings are +/- 3dB).
