decreases as filter restriction approaches 8" to 9" water column. If restriction cannot
be reduced by cleaning and pulsing, filters should be replaced.
F. DST-6 Filter Box Cleaning
The DST-6 Filter Box provides a collection area for the dust pulsed off the filters.
Once a month, the filter box should be inspected and cleaned. Remove all four filters
from the box. Wash dust from the box walls and floor. Open access door on opposite
side and direct water through filter purge ports to clean opposite wall and around
pre-cleaner area.
1. Pressure Taps - Four static pressure sensing taps are found inside the DST-6
box, two are located in the dust collection box, one is in the pre-cleaner chamber
and one is in the cleaner air exhaust area and is reached through the access
door.
Proper operation of the DST-6 requires these static pressure taps be inspected
and kept clean. Remove pressure sensing lines at bulkhead fittings and use com-
pressed air to back blow through static pressure taps. An assistant should be
able to hear the air if static pressure tap is clear.
G. AIR COMPRESSOR
The Bendix Air Compressor, belt driven on the end of the sweeper PTO assembly, is
critical for the proper pulsing of the DST-6 filters. Proper service and maintenance is
critical. Should a problem develop, take the unit to a local authorized Bendix Dealer.
Should the compressor need replacement, a Bendix re-manufactured compressor
will be provided with full OEM warranty.
NOTE: For tracking purposes, the re-manufactured compressor will have a differ-
ent Bendix part number than the OEM compressor, but the compressors
will be identical.
