Spark Proof Exhaust Fan

Amca a spark resistant construction.

Spark proof exhaust fan. Src is commonly used in systems where a spark in the airstream could cause fumes or contaminants in the airstream to ignite. How is src defined. Choose the wheel diameter voltage and motor horsepower. Typically aluminum is the non ferrous material used but for certain applications such as high temp where aluminum cannot be used twin city fan has the capability to use alternative materials including.

Type a fan construction requirements specify that all materials that are in contact with the air stream be constructed of spark resistant nonferrous material such as aluminum or brass. These fans offer the highest degree of spark resistance. Use spark resistant blowers from grainger wherever the need for efficient exhaust combines with the potential for fire or explosion such as a kitchen or chemical laboratory. Common applications include paint booths chemical storage areas and lab fume exhaust systems.

Proper spark resistant fan selection should involve consideration of the application s ambient location and conditions since the fan will need to operate reliably in that environment. Type a construction requires that all parts of the fan or blower that are in contact with the air stream be made of spark resistant nonferrous material such as aluminum or brass. Airstream parts are constructed out of non ferrous materials. These fans may include amca type a type b or type c spark resistant construction and an nfpa 70 nec compliant explosion proof motor.

The amca has three main classifications for spark resistant fans and blowers. The class division system is based on class division and group. These belt drive backward inclined blowers offer you spark resistant aluminum wheels in a wide range of choices. The user shall electrically ground all fan parts.

Spark resistant construction is an amca requirement when dust fibers gases vapors or liquids could cause an explosion in the case of any kind of spark. As an explosion proof fan. They will either use an a rating type a b rating type b or c rating type c. Additionally our fans are rated as atex explosion proof.

Highest degree of spark resistance. Spark resistant fan construction is the technical term for industrial fans typically classified as explosion proof exhaust fans.

The use of aluminum or aluminum alloys in the presence of steel which has been allowed to rust requires special consideration. When referring to a fan spark resistant construction is used.
