Smoke and Fumes from Extruding & Injection Molding:
M266O media based air cleaner
The process of extruding itself creates a good deal of smoke that should be filtered with an air filtration system. Extruding and molding can be done with a variety of materials including plastics, rubber and various metals. In addition to the smoke created, a good deal of gases are also generated, particularly when working with plastics or rubber. These gases, commonly referred to as VOCs (volatile organic compounds) can be moderately harmful and should be taken into consideration. It is important to understand that gases (VOCs) are not filtered by the same mechanisms as particles (smoke) and require different filters. While particles (smoke in this instance) can be filtered by multiple processes such as electrostatic precipitation, HEPA filters, cartridges and a variety of other media based filtration methods, the gases can really only be either exhausted to the outside, or filtered by activated carbon.

Portable Air Cleaners for Purging:
A common air pollution problem associated with molding comes from the purging of the molds for injection molding. When changing materials or colors, the molds are heated to burn off any remaining materials so as not to contaminate the new parts with old material. Portable air cleaners are frequently used during this purge cycle as not all of the molds would typically be purged at once. Air Quality Engineering manufactures a wide line of portable air filtering systems for use with this specific problem. Portable systems can also be configured with activated carbon filters in addition to a wide variety of particulate filters to address both the smoke and vapor problem.
