Fan applications with airstreams of explosive or flammable particles or gases require spark resistant system components for the safe handling of such airstreams. Spark Resistant Construction (SRC) is intended to minimise the potential for any two or more fan components to generate sparks within the airstream by rubbing or striking during operation. AirEng can design and manufacture fans to meet AMCA SRC specifications, NFPA containment standards, and ATEX requirements.

The three most common types available are AMCA A, AMCA B, and AMCA C. AMCA A (Airstream) SRC includes all airstream parts constructed of a spark-resistant alloy. AMCA B (Wheel) SRC includes the fan wheel constructed of a spark resistant alloy and a buffer plate around the housing shaft-hole opening. AMCA C (Buffer) SRC includes a spark resistant alloy buffer affixed to the housing interior adjacent to the wheel back-place, a spark resistant alloy inlet cone, and a buffer plate around the housing shaft-hole opening.

AirEng designs and manufactures customised and tailored air-movement solutions specific to your required application. Contact us to request a quote for spark resistant construction equipment.
