Paintbooth Filtration
Downdraft
Prep Station
Crossdraft
Flanders offers a wide variety of filtration products for
downdraft and crossdraft paintbooths and prep sta-
tions. For the most part, fitlration products required for
all of these fall into three general categories which are
color coded to the drawings at left which indicate their
placement in each type of booth.
Air Intake filters are as important to a great paint job
as the booth itself. The intake filters are the primary
defense against foreign particles landing on the paint-
ing surface. Any particle larger than 10 microns can
cause a defect on a paint job. Intake filters are typi-
cally either panels or pads. Intake filters in a down-
draft booth and prepstations are above the painting
surface. In crossdraft booths, they are typically in the
door.
Exhaust filters play an important role in maintaining
proper air flow balance, increasing cleanliness of
exhaust stacks, reducing maintenance of the exhaust
system and in controlling V.O.C. emissions. The pur-
pose of exhaust filters is to capture overspray parti-
cles and remove them from the airstream as air is
removed or recirculated back into the booth.
Crossdraft and semi-downdraft booths use media
pads which are placed on grids in the rear wall or
lower portion of the side walls in filter housings.
Downdraft booths use a long pad that is placed into a
pit below the painting surface.
A prefilter is designed to filter out large particles
before the air reaches the intake filter. This prolongs
the life of the intake filter, increases airflow in your
booth and reduces maintenance costs on the intake
stack and mechanical parts. The prefilter is typically
found only in heated booths. Crossdraft booths will
very rarely have a prefilter. In downdraft and semi-
downdraft booths, the prefilter is located somewhere
along the duct-work bringing air into the booth.
