strength.


HEPA: High Efficiency Particulate Air
3.3.2. Filter Packaging, Shipping and Handling
Packaging practice varies among the filter unit manufacturers.
Filter units are typically packaged in cardboard cartons with
varying approaches for strengthening the container and making it
impact-resistant. Shipping cartons are typically marked with a
vertical arrow and "This Side Up" (Figure 5). A filter unit is placed
in the carton so the pleated folds are vertical (running from top to
bottom), versus side to side.
The filter is typically shipped in the original carton or package provide by the filter manufacturer.
This carton or package provides good storage and maximum protection from dirt and moisture.
Store and move HEPA filters upright in the shipping carton. Minimize handling of the filter.
During installation, remove the filter from the shipping carton and install directly into the oven.

LCC oven chamber temperature transitions must not exceed
1.5°C/minute to maintain class 100 chamber conditions. For ramp
rates greater than 1.5°C/minute and up to 5°C/minute, the LCD model
will maintain class 100 chamber conditions.

Despatch does not recommend using D.O.P. or other organic challenge
agents.

Ship, handle, store and install HEPA filters with pleats positioned
vertically. Horizontally-positioned pleats risk breaking at the adhesive
line of the filter medium. Horizontally-positioned pleats also collect
entrapped material on “shelves.” The accumulated weight of the
entrapped material may cause sag and lead to early failure of the filter
unit.
