N.R. Murphy Limited supplies an unmatched range of dust-collection equipment, but its lineup spans even further. Many high-quality accessories are available too, like rotary air locks, dumpster bins, filters, silencers, exhaust fans, and abort dampers. N.R. Murphy recommends its abort dampers for workplaces that face fire or explosion hazards, like sawmills. When installed in the clean air stream of a filtering system, an abort damper functions as an instant aborting device that expels the air to the atmosphere when a spark- or fire-detection system activates it.
Heavy gauged reinforced steel
Fire and explosion are major risks in such sectors as forestry, wood processing, and pulp and paper. Abort dampers are designed to protect workers and facilities in these circumstances. These units are built out of heavy gauge reinforced steel and are vital for any work environments that convey combustible materials pneumatically.
In using these abort dampers, it is wise to wait until after switching off the exhaust system before activating and resetting them manually. Another way is to activate the device manually during filtering issues that are not too serious, as this allows all manufacturing operations to go on with no interruption until the system gets repaired. Customers can use abort dampers during the summer season to expel cleaner return air to the atmosphere when plant doors and windows are open, unless air conditioning is being used.
Fourteen sizes of abort dampers are available, and each size is good for a different sort of material-handling exhaust system. The dimensions range from 43 by 20½ by 37¾ inches, or size 11, to 107 by 58½ by 114¼ inches, which is size 48. The weights of these devices range from 195 to 1,545 pounds. N.R. Murphy abort dampers always comply with the strict standards of the National Fire Protection Association Code 664 section 22.214.171.124.2 (2) for recycling air from a wood refuse exhaust system.
N.R. Murphy makes a broad range of dust-collection accessories and components to upgrade or supplement existing systems. Always trust N.R. Murphy for the best in industrial air-quality solutions.
