Canada Blower industrial aerfoil (AF) blowers and fans are supplied with aluminum wheel or corten wheel to meet requirements of AMCA A, and AMCA B spark resistant construction. Mild steel wheels are of all welded construction. If higher pressure is required wheel can be furnished of high strenght steel. Stainless steel wheel in 304 SS, 316 SS, 316 SS, 2205 SST are supplied for corrosive applications, or high temeparature applications. The pressure curve remains stable at the top are of the fan curve and to the right of the pick point.
Ventilation equipment manufactured for operation in potentially explosive environments has been required to comply with the EU’s ATEX Manufacturer’s Directive (94/9/EC). The ATEX Directive applies to all countries in the EU and the European Economic Area (EEA).
ATEX (ATmosphères EXplosibles) is a conglomeration of European Union (EU) directives outlining equipment installed and operated in potentially explosive atmospheres. The ATEX directive coordinates various technical and legal conditions throughout Europe to ensure a high level of safety for the end-user by reducing the explosion risk through established design methods.
The ATEX Directive places the burden directly on the end-user. The end-user is responsible for the following:
• Prevention of the formation of explosive atmospheres and possible ignition threats
• Evaluating the risk of explosion for their specific atmosphere and process
• Eliminating or reducing the level of risk for a specific atmosphere and/or process
• Classifying the work and equipment environment into “zones/categories” for determining preparation of documentation for explosion protection
• Identifying hazardous areas and utilizing warning signs to alert personnel and equipment suppliers of the potential hazard
• Specifying suitably safe equipment for use in the zone to the engineer or equipment supplier
The end-user is required to evaluate the environment where equipment is to be located and operated. When evaluating hazardous locations, it is important to consider the hazardous material (gases or dusts) itself, how the material may interact with the surroundings (atmosphere, equipment and personnel), likelihood of explosion due to the surroundings, and the level of any anticipated effects.
Since the introduction of the ATEX Directives in 2003, mechanical equipment manufacturers have been subject to similar certification requirements as electrical equipment manufacturers. Fan manufacturers have been allowed to subscribe to the manufacturing process as detailed in the European Standard EN 14986:2006, “Design of fans working in potentially explosive atmospheres,” which provides a guide for meeting the ATEX Directive (94/9/EC).
European Standard EN 14986 outlines manufacturing and design criteria for fan manufacturers to adhere to. Such design requirements include, but are not limited to, permissible material pairings, minimum clearances between rotating elements and the fan casing, casing design, bearing selection, impeller-to-shaft attachment and motor/electrical selection. As long as the fan manufacturer meets the requirements of the European Standard EN 14986:2006, they are in compliance with the ATEX directive (94/9/EC) ventilating.com fanblower.com highpressureblower.net industrialblowerfan.com industrialfanblower.net industrialfanblower.com pressureblower.net northernindustrialsupplycompany.com industrialpressureblower.com tenderall.com chicagoblowercanada.com cbblower.com buffaloblower.com buffalofan.com nis-co.com canadianblower.com olegsystems.com canadablower.com abbblower.com acmefan.net industrialblower.net fansandblowers.net americanblower.net barryfan.com cincinnatifan.net canadafans.com barryfan.net greenheck.net pennbarry.net pennfan.net tcffan.com.
