Cardboard Framed Panel Filter with Columbus® HC Collector
Cardboard Framed Panel Filter with Columbus® High Capacity Multilayer Collector.
Columbus Industries baffle-type High Capacity Multilayer Collector provides excellent efficiency and very high holding capacity.
It utilizes eight layers of kraft media, each slit and expanded into a mesh with baffle-like surfaces, creating a multistage collection design.
The cardboard frame gives the filter structural rigidity, low cost and easy disposal.
The Cardboard Framed Panel Filters with Columbus® HC Collectors are the most balanced choice to obtain storage capacity and good efficiency (Efficiency Class: G3 – EN779).
Available in custom frontal sizes with a thickness of 24 mm or 48 mm.

- Lx+ (Large Crossed Layer)
- S (Small Layer)
- MM (Mini-Mesh Layer)
Efficiency & Holding
Overspray collectors are not commodity items and all do not perform equally well on every coating. Specific types of coatings require certain collector designs and performance levels.
The four primary categories used to assess the overall effectiveness of a particular overspray collection system are as follows:
EFFICIENCY (formally known as “arrestance efficiency” or “weight arrestance”)
The average percentage of particulate extracted or collected from the exhaust air. The higher the collector efficiency, the cleaner the exhausted air and spray booth ducts, fan, neighboring properties, plant roof, etc. Higher efficiency lowers booth maintenance costs and, with less buildup, greatly reduces the chance of a duct fire.
The measure of resistance encountered by the particulate-laden air as it passes through the collector. (Generally it is stated in inches of water column, the static pressure required to draw air through the filter.) As the collector begins to load, the resistance increases. The velocity of the air through the booth also influences the initial resistance figures and, therefore, the holding capacity and service life. The importance of proper airflow in overspray collection cannot be overemphasized. The uniformity of airflow and increased efficiency minimizes the amount of overspray deposited where it is not wanted – in difficult to clean areas within the booth, inside of the exhaust duct, on fan blades, plant roof, neighboring properties, parked cars, etc.
The amount (weight) of overspray a collector will hold before its resistance to airflow becomes prohibitive. A collector should be able to hold overspray throughout its entire depth, which is referred to as depth loading.
The length of time a collector performs effectively in terms of hours or shift periods before the resistance to airflow becomes prohibitive.
The performance of the product described in this page varies and is characteristic of each individual installation; it must therefore be measured on the system.
As a guideline, we provide some experimental data:
