Flame Arrestors
NAO FLAME ARRESTORS
Engineered Flame Arrestors for Critical Process Safety
NAO designs and manufactures high-performance Flame Arrestors engineered to protect vessels, storage tanks, flare systems, stacks, and process equipment from the dangers of flame propagation and explosive gas ignition.
Every flame arrestor is custom-engineered to meet the specific requirements of your application, ensuring reliable protection while maintaining optimal process performance.
Deflagration and Detonation Protection
Our flame arrestor product line includes both deflagration and detonation arrestors designed to stop flame fronts before they can enter and damage critical equipment. These systems provide proven protection against flashback events in applications where flammable gases, vapors, or air-fuel mixtures are present.
By dissipating heat from the advancing flame front and reducing temperatures below the ignition point of the process gas, NAO Flame Arrestors help prevent explosions, equipment damage, production downtime, and personnel hazards.
