Abort damper units by N.R. Murphy: perfect for explosive environments

N.R. Murphy can supply abort dampers.

N.R. Murphy Limited is a leading supplier of dust-collection equipment, but its portfolio is wide-ranging, with a number of high quality accessories like rotary air locks, dumpster bins, filters, silencers, exhaust fans, and abort dampers. These abort damper units are recommended for sawmills and other businesses that face fire/explosion risks.

When installed in the clean air stream of a filtering system, an abort damper serves as an instant aborting device that expels the air to the atmosphere when activated by a spark- or fire-detection system.

With 14 sizes available

Made out of heavy gauge reinforced steel, N.R. Murphy abort dampers are essential for workplaces that convey combustible material pneumatically. In such industries as forestry, wood processing, or pulp and paper, fire and explosion are constant hazards. Abort damper units are designed to protect workers and plants in such circumstances.

To use these abort damper units, the N.R. Murphy team recommends waiting until after turning off the exhaust system before activating and resetting them manually. Another way is to activate the device manually during filtering problems that are not excessively serious; this allows the manufacturing operations to carry on with no interruption until the system is repaired. During the summer months, businesses can use abort dampers to expel cleaned return air to the atmosphere when plant doors and windows are open, unless air conditioning is being employed.

N.R. Murphy offers 14 different sizes of abort dampers; each one is good for a different kind of material-handling exhaust system. The dimensions range from 43 by 20½ by 37¾ inches – size 11 – to 107 by 58½ by 114¼ inches, or size 48; weights of these units run from 195 to 1,545 pounds. The company reserves the right to alter any of these dampers without notice. In addition, N.R. Murphy abort dampers always comply with the stringent standards of the National Fire Protection Association Code 664 section 8.2.2.7.4.2 (2) for recycling air from a wood refuse exhaust system.

For the best in industrial air-quality equipment, the name to trust is N.R. Murphy.
