10. Slide the spring/clamp up over the hose and 3/8” hose barb until it
fully seats against the barb’s hex, see Figure 10.
11. Tighten the hose clamp using screw driver or 1/4” nut runner. DO
NOT OVERTIGHTEN!
12. Replace filter(s) into unit. Note: Make sure NOT to pinch hose
- position Vibra Pulse
hose into the center of the cartridge
filter. Engage filter mechanism if required.
13. Reinstall dust tray.
14. Reinstall filter access door.
15. Reconnect air line and power.
16. Test the Vibra Pulse
system for operation manually or electrically
as appropriate for your unit’s configuration.
FILTER SERVICE
The filters have been charged with pre-coat (an inert white mineral dust) at the factory. This pre-
coat material will increase initial efficiency and help to extend the cartridge filter life. Upon initial unit start up,
go through one cleaning cycle (see filter cleaning below), most of the pre-coat will be removed from the filter
and fall into the dust pan. The remaining pre-coat will stay on the filters. Save any material that falls into the
pan for treating replacement filters. A Material Safety Data Sheet (MSDS) will be furnished upon request.
Please contact the Airflow Systems Representative or the AFS Factory.
Filter service is required when a reduction of airflow (suction) is observed. The optional pressure gauge is
used to judge the amount of particulate collected on the filter. As the worker gets accustomed to the units’
effectiveness of capture, and the associated gauge reading, the gauge can then become an indicator of filter
condition.
The optional pressure gauge is calibrated as follows:
In most applications, with clean filters, turn unit on and mark the pressure reading on the
gauge. Make a second mark at 2.0" higher than initial reading (i.e. if initial reading is 3.0" the
second mark should be at 5.0"). Note that a reading of 5.0” is typical of when the filter should
be cleaned in most applications.
NOTE
Unit can continue to run safely beyond the 5.0 " pressure differential recommended,
however performance will be reduced. Exceeding 6.0" pressure differential across the
filter may cause reduced filter life.
