Stop Explosive Dust in Its Tracks With our Proprietary IDA DeltaMAXX Filters

Save the lives of your employees in the metalworking industry!

As a metal fabricator you’re no stranger to the everyday dangers of the metalworking industry. Metalworkers encounter hazardous smoke, fumes, sparks, and dust. The inhalation of smoke and fumes can cause short term health effects such as respiratory issues to eye irritations, and long term health effects such as chronic lung infections. The most common hazard in the metalworking industry is a combination of dust and sparks which creates explosive dust.  

How Does Explosive Dust Create An Explosion?

The accumulation of combustible dust occurs during processes such as grinding, buffing, and sand casting. During these processes the dust can accumulate in the air ducts and vents making it a recipe for disaster. The Occupational Safety and Health Administration (OSHA) explains the 5 components that create the prime environment for an explosion.

A dust explosion requires 5 components to create the “Dust Pentagon”.

  • A fuel that will burn
  • Oxygen
  • A source of ignition – sparks or heat
  • The suspension of the dust particles in just the right amount
  • Confinement of the dust particles in a limited amount of space.

This provides the perfect formula for the pressure to build up and cause an explosion.

How does the metalworking industry keep explosive dust to a minimum?  Implementing a cleaning protocol, and training employees to identify a hazardous situation is the first line of defense. Abiding by the guidelines put into practice by OSHA, and having a highly efficient ventilation, and dust collection system will keep the combustible dust to a minimum.

Imperial Systems continues to dedicate itself to ensure the safety of those in the metalworking industry. This is why when our proprietary IDA (In-line Deflagration Arrester) DeltaMAXX filters were designed to fit our CMAXX Dust Collector System.  It’s been PROVEN to confine a deflagration and stop a flame front.  In order to safeguard those in the metalworking industry we tested our CMAXX System numerous times with the IDA DeltaMAXX filters and all tests with each filter was able to isolate the flammable dust and completely stop a flame front each and every time.  Not only was it capable of stopping the deflagration, but there were zero traces of flames or sparks in the clean air plenum or down from the the IDA filters. This proves that the CMAXX Dust Collector System is one of the best in the industry.  

We wanted to do a comprehensive test on the effectiveness of the IDA DeltaMAXX filters so we covered the explosion venting on the CMAXX to see how it could withstand the full force of an explosion. The results show how the explosion changed course through the IDA DeltaMAXX filters, and caused very little damage to the filters.  

The IDA filters internal cages remained intact with no visible signs of deformation or melting.  All explosion testing was conducted by a third party. The CMAXX Dust Collector System along with IDA DeltaMAXX filters is now IDA certified, with the end result being safety for those working in the metalworking and manufacturing industries.
