N.R. Murphy abort dampers boost safety in sawmills and more

Abort dampers are recommended for explosion risks.

Although businesses across Canada and beyond rely on the N.R. Murphy Limited team for its broad selection of dust-collection equipment, the manufacturer offers a variety of other options. Examples include high-quality accessories, such as rotary air locks, dumpster bins, filters, silencers, exhaust fans, and abort dampers. Abort dampers are recommended highly for work environments that face considerable fire and explosion hazards, especially sawmills. They are essential for workplaces that convey combustible material pneumatically.

Heavy gauge reinforced steel

Abort dampers are made out of heavy gauge reinforced steel and designed and manufactured to protect workers and facilities in fields and sectors in which fire and explosion are substantial dangers – such as forestry, wood processing, and pulp and paper. When they are installed in the clean air streams of their filtering systems, these units serve as instant aborting devices that expel the air into the atmosphere as soon as spark- or fire-detection systems activate them.

People who use these abort dampers should wait until after switching off the exhaust system before resetting them manually. Another way is to activate the device manually during filtering issues that are not too serious, as this allows manufacturing operations to continue with no interruption until the system is fixed. Abort dampers can be used during the summer months to expel cleaner return to the atmosphere when facility windows and doors are open, unless air conditioners are running.

Fourteen different sizes of these abort dampers are available, each one compatible for a specific type of material-handling exhaust system, and they all meet the strict standards of the National Fire Protection Association 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, including abort dampers. For the peak of industrial air-quality options, N.R. Murphy is the name to trust.
