EuroSupra© 2 Overspray Collectors
Columbus Industries’ EuroSupra® 2 overspray collectors employ both baffle and strainer principles, performing with high efficiently and excellent holding capacity.
In these collectors, five layers of slit and expanded kraft with multistage designed baffle openings are combined with one synthetic layer, which is less dense than the EuroSupra© 1, but still provides high efficiency collection for a wider range of coatings.
EuroSupra® 2 overspray collectors have a longer service life when employed with coating that have slightly drier overspray.

Layers
The EuroSupra© 2 Overspray Collector consists of the following layers, in the sense of Air Flow:
- L (Large Layer)
- Lx (Large Crossed Layer)

- P2 (Polyester Type 2)
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.
AIRFLOW RESISTANCE
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.
HOLDING CAPACITY
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.
SERVICE LIFE
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.
