Is my fan explosion proof?
While there are enclosures and motors that are rated explosion proof, it is not possible to rate a fan as explosion proof. The Air Movement and Conditioning Association (AMCA) Standard 99-0401 Classification of Spark Resistant Construction was developed to meet the need for fans in potentially explosive environments.
What does explosion proof fan mean?
A fan or blower for a hazardous location, often called an explosion proof fan, may be required where flammable or combustible materials are in the atmosphere or being conveyed. These fans may include AMCA Type A, Type B, or Type C Spark Resistant Construction and an NFPA 70/NEC compliant explosion proof motor.
Are brushless fans explosion proof?
The use of a brushless motor eliminates the sparking and electromagnetic interference (EMI) that may occur with a brushed motor. Using a spark-proof IP68-ATEX rated EC fan eliminates the possibility of explosions or fires in these applications, providing maximum protection with reduced energy usage.
What is an ATEX fan?
ATEX fans are fans designed for use in potentially explosive atmospheres and are governed by EU Directive 2014/34/EU. This Directive is intended to increase safety by using a logical risk identification and mitigation method for design manufacture and use.
Where can you use an explosion proof fan?
Explosion proof fans or hazardous location fans and blowers are an essential part of a warehouse, plant, mill, spray booth, tank, confined space or any other area where ignitable fumes, gases or dust may be present.
What is the rating system for explosion proof?
Explosion Proof Ratings. These ratings are designed to classify the hazard levels of working environments and the different motor features available. In order to better understand this concept, we will go into detail on the levels of complexity of this rating system. There are four components to this grading system: class, division, group,
What are the requirements for an explosion proof enclosure?
To meet the criteria for the explosion proof rating, an enclosure must be able to contain any explosion originating within its housing and prevent sparks from within its housing from igniting vapors, gases, dust, or fibers in the air surrounding it.
What are the different classes of explosion proof?
Explosion Proof Classifications Class Definitions Class I Locations: Are those in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. Class II Locations: Are those which are hazardous due to the presence of combustible dust. Class III
