Use abort dampers by N.R. Murphy when conveying combustible material

N.R. Murphy abort dampers are recommended for sawmills and other hazardous industries.

N.R. Murphy Limited is known as a top provider of dust collectors. But the company’s inventory is broader than that. Customers also have access to high-quality accessories, such as rotary air locks, dumpster bins, filter bags, and abort dampers. N.R. Murphy highly recommends its line of industrial abort dampers for businesses that face fire or explosion hazards – such as forestry sawmills, for example.

To protect workers and facilities

Each of these abort dampers is an instant aborting device, built out of heavy gauge reinforced steel, that a company installs in the cleaned air stream of a filtering system. The device expels the air into the atmosphere after a properly installed spark- or fire-detection system activates it. This makes industrial abort dampers an essential inclusion for facilities that pneumatically convey combustible material, in sectors like wood processing and pulp and paper. The risk of fire or explosion is always present in this industries, and abort dampers are designed to protect workers and plants in the event of such a catastrophe.

Other practical advantages

The best way to use industrial abort dampers is to wait until after turning off the exhaust system before activating and resetting them manually. It is also possible to activate the device manually during filtering problems that are not too serious, allowing the manufacturing process to continue without interruption until the system is repaired. During summer, manufacturers can operate abort dampers to expel cleaned return air to the atmosphere when the facility windows and doors are open, unless air conditioning is being used.

Fourteen different sizes of abort dampers are available from N.R. Murphy, for different types of material-handling exhaust systems. Dimensions go from 43 by 20½ by 37¾ inches (size 11) to 107 by 58½ by 114¼ inches (size 48), while approximate weights range from 195 to 1,545 pounds. N.R. Murphy reserves the right to make changes to the product without notice.

These abort dampers meet the strict 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.
