Any filter blockage will result in serious problems. As the industrial combustion system bogs down under a clogged filter, your process may not get the required input. Clogged filters put undue strain on the combustion air blowers over time, so your electrical and motor maintenance costs may escalate. And, worst of all, the burners may go fuel rich. This wastes fuel and can create carbon, which at its best is an insulator and a mess. At its worst, it is a fire hazard.
