12 - 1 High efficiency filter / dust filter for VAM350-2000FB
12 - 1 - 1 Information for filter selection
1
choose required airflow
2
choose the filters
3
add up all the pressure drops of the duct system on the installation site and the filters
[For filter characteristics, refer to D-drawings]
4
compare this with the unit performance characteristics to see resulting airflow & ESP
Download the VAM selection software on the Daikin extranet for easy selection
12 - 1 - 1 - 1 Choose required airflow
Choose the required airflow based upon the application/information
12 - 1 - 1 - 2 Choose the filters
Depending on the application prefilters and/or dust filters will be needed.
