Overspray collectors are not commodity items and all donot perform equally well on every coating. Specific types ofcoatings require certain collector designs and performance levels.Acontinuing dedication by Columbus Industries to research and develop better overspray collection systems has brought about a complete, highly versatile line of cost- effective dry overspray collectors. Some Columbus Industries collectors provide optimum performance under general conditions while others are designed to provide maximum performance under speciү́c spray booth applications. One of Columbus Industriesoverspray...

The High-Capacity Mini-Mesh Collector is excellent for use with a wide range of coatings and especially with heavier, tacky-type coatings, conventional coatings and in High-CapacityMini-Mesh Collector also provides excellent efficiencyand very high holding capacity.The High-Capacity Mini-Mesh Collector utilizes eight layers of slit and expanded kraft, again creating a multistage collection design.The first three layers of this collector employ extremely large baffle openings for Supra ll Mini-Mesh Collector also employs...

Differentcoatings react differently to any filter media from a resistance and service life standpoint Columbus Industries֒collectors fully address those differences. HIGH-CAPACITY SUPRA I & II/ HIGH-CAPACITY SUPRA I & II MINI-MESH > Multiple-Pocket Polyester Bags fromColumbus Industries are designed to provide a highly efficient secondary or tertiary ٯ́ltering media while maintaining a low resistance to airflow.The pocket construction, or extended surface area, makes these benefits possible.These collectors, which are available in a wide array of pocket counts, frame configurations and material...

This flexibility allows for the specific requirements of an end user to be designed into the system. The roll concept saves time which is particularly important in high- production situations. Less frequent replacement of the secondary (downstream)media should always occur.These readily replaceable rolls allow for easy maintenance and reduce downtime of production equipment. the flexible design accommodates the use of a single layer of media or two layers of rolls or a roll and pad combination. 4) Determine the type of collection system best suited toyour needs.

We at Columbus Industries are committed to promoting anincreased awareness concerning the environment and our industrys relationship to it.As the concern over environmental issues becomes moreurgent, the need for higher efficiency ү́lters increases. The chart on page 10 shows the relationship between filter efficiency and the amount of overspray passed through the filter and into the environment.The more efficient the filter, the less overspray passed intothe environment. Higher efficiency is especially important when VOC-abatement systems are being used. > ?Overspray collectors constructed of multilayered,...
