An important safety feature in a dust collector is a fire suppression system that is instantly activated in the event that particulates are accidentally ignited during welding or other operations. The best collectors offer a system that can detect both the presence of smoke and heat. Typically, when smoke is detected a damper is closed to eliminate oxygen and smother a fire. If heat is detected, FM-200 fire suppressant gas is deployed to extinguish the fire.
When it comes to buying industrial ventilation equipment, it can be difficult for welders and fabricators to evaluate a dust collector’s capabilities properly. What buyers see most often are claims about construction, reliability, or how long a supplier has been manufacturing them. Even though these claims have become standard promotional tactics, they do little to help a buyer differentiate one ventilation unit from another.
To compound the matter, manufacturing’s needs have changed over the past 20 years. Improving plant safety and productivity are constant, pressing issues. Obviously, achieving regulatory air-quality standards is an important factor in reaching those goals. But, creating an effective ventilation system requires that a wide range of variables be considered, from the type of dust and fumes produced to the air-flow dynamics that carry the particulates and pollutants throughout a plant.
Here are five important features for buyers to examine to ensure the right factors are considered when choosing a dust and fume collection system.
1. Rough And Ready — A well-designed dust collector integrates every component needed to make it operational (cabinet, motor, blower, control panel, safety features, filters) into one cohesive design. The only things that should be required on-site are simple electrical and compressed air connections. Too often buyers have to spec a cabinet and the mechanical components separately, and then are faced with hours or days of labor expenses to wire and connect the individual components.
Engineering the proper fit and performance, compounded by this more complex installation makes it more expensive and challenging. Today, choosing a complete package eliminates the need to source and spec individual components, or schedule and coordinate a more complicated installation.
