The range of S&P explosion-proof fans includes fans of all types: channel, axial, centrifugal and roof fans, altogether 150 series. They differ in capacity, design and protection class. Almost any S&P fan may be manufactured in explosion proof performance.
Explosion proof S&P fans are available with the following protection classes: 2ExeIIT3, 1ExdIIBT4/T5, 1ExdIICT4 and Ex tD A22 T125oC/T135oC (the last two classes are used to move explosive dust).
Class 1ExdIICT4 is suitable for air+hydrogen mixture moving. This level of equipment protection together with the stainless steel performance allow the fan to operate in accumulator rooms.
