Metalworking Emissions Control

Air Clear has extensive experience in controlling the emissions from Metalworking Manufacturing processes. We have Air Pollution Control Systems in operation on many production lines.

Metalworking process exhaust contains a variety of particle sizes ranging from submicron and larger, and the objective is to control the opacity and associated odor resulting from the particulate emissions.

In cases where VOC control is not required, Air Clear recommends the use of an Air Clear Coalescing Fiberbed Filter Mist Collector System to control opacity. Air Clear systems use fiberbed diffusion filters to collect the submicron particulate that is the cause of opacity. Fiberbed filters are designed to collect both solid and liquid particulate, and have been used successfully for many years to control oil mist emissions effectively and economically.

In some cases an Indexing Drum Pre-Filter System using a durable poly pre-filter material is offered to remove oils, lint, waxes, and particulate from the exhaust to protect the main filters and extend their life. As the filter media gets dirty, the pressure drop increases. At a fixed point the drive motor indexes pulling off the dirty media and replacing it with clean media.

In cases where Volatile Organic Compounds (VOC) control is required, Air Clear recommends the use of a Regenerative Thermal Oxidizer (RTO) utilizing a variety of Pre-Filtering”Technologies to remove contaminants up steam of the RTO. The plugging problem is exasperated due to the numerous types of contaminants plugging the RTO. The right pre-filter has resulted in the adaptation of several filtration technologies which have been a part of Air Clear’s product line for years.
