Highest degree of spark resistance.
Spark proof exhaust fan.
They will either use an a rating type a b rating type b or c rating type c.
Airstream parts are constructed out of non ferrous materials.
Also amca air movement and control association rates fans and blowers by spark resistance.
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 may include amca type a type b or type c spark resistant construction and an nfpa 70 nec compliant explosion proof motor.
Src is commonly used in systems where a spark in the airstream could cause fumes or contaminants in the airstream to ignite.

Common applications include paint booths chemical storage areas and lab fume exhaust systems.
The user shall electrically ground all fan parts.
The amca has three main classifications for spark resistant fans and blowers.
Choose the wheel diameter voltage and motor horsepower.
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.
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.
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.
These belt drive backward inclined blowers offer you spark resistant aluminum wheels in a wide range of choices.
The class division system is based on class division and group.
As an explosion proof fan.
The amca a spark resistant construction is the highest degree of spark resistance.
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.
When referring to a fan spark resistant construction is used.
Amca a spark resistant construction.
Additionally our fans are rated as atex explosion proof.
It is critical that the right type of spark resistant construction is selected and that the motor is properly classified for your area.
The use of aluminum or aluminum alloys in the presence of steel which has been allowed to rust requires special consideration.
These fans offer the highest degree of spark resistance.
How is src defined.
