The M-D Pneumatics® EX ATEX rotary positive displacement blowers were designed to be able to perform to high-quality standards specifically for hazardous areas as defined in Directive 2014/34/EU and ISO/IEC 80079-34/36/37 standards. A hazardous area is defined as an area in which potential or existing explosive atmospheres are present in quantities that require special precaution for the construction and use of equipment. The EX ATEX series blowers are designed for critical applications in the chemical and petrochemical industries meeting Zone 1&2 requirements for Gas Groups IIA, IIB & IIB+H2 while operating in T3-T1 temperature classes. Rated up to 34 PSIG max allowed working pressure (MAWP) or 15” Hg dry vacuum.
