Columbus Industries Inc., Ashville, Ohio, provides no-charge laboratory testing service to its distribution partners. The primary function of the laboratory facility is to determine the performance levels of filtration products used in the spray booth. Several test methods are employed, including ASHRAE 52.1, which yields Arrestance Efficiency and Holding Capacity data for intake and exhaust filters as well as pressure-drop information. The liquid and powder coatings from actual end-user facilities are utilized as the challenge aerosols for the testing (52.1-modified). Additionally, the laboratory performs various physical testing of samples at the request of the company's partners.

Holding capacity and resistance-to-airflow data are of particular relevance to end users, as this data provides the basis for calculating filter service life and energy usage/operating costs, facilitating planning and future cost expenditures for those involved with liquid and powder coatings.
