HEPA Filter.
CF-ECO can be equipped with a HEPA Filter on the outlet side.
Compressed Air Supply for Jet-Pulse Filter Cleaning System.
A constant 80 psi(6 bar) pressure is recommended (not over 90 psi and not below 70
psi). Reasonably clean and dry air is required. Oil and/or water will reduce the
lifetime of the filter.
Connect the included 3/8" compressed air hose to the compressed air system. Test
by opening the valve 5-10 seconds. You should hear a vigorous "Jet-Pulse"
oscillation from inside the filter unit the entire time. If you don't, your air supply is not
maintaining the 30 cfm (800 l/m) flow rate required to operate the "Jet-Pulse"
cleaning system at spec. Check the compressed air system.
Jet-Pulse Cleaning
When the filter gets dirty the airflow volume will drop off to a level where capture of
contaminates is not adequate. Activate the Jet-Pulse cleaning.
1. Turn unit off. Disconnect electric power.
2. Connect the compressed air hose to the air system.
3. Open the valve on the unit 3 times 10 seconds. 30 seconds pause between
each 10 sec.
4. CF-Eco, open the door and take out the dust tray and dispose of material in
accordance with local regulations. Put the dust tray in again and close the
door.
5. Restart the unit. In many applications cleaning once a day or once a week is
sufficient or even less often. In some applications multiple cleanings per day may
be needed.
Replacement of Filter.
At some point all filters will retain enough non-removable dust such that even Jet-
Pulse cleaning becomes ineffective. Filter replacement is required at that point.
Check Jet-Pulse actuator mechanism at the same time.
1. Turn unit off. Disconnect electric power, disconnect compressed air.
2. Open door and loosen knob in center of filter. Remove filter from unit.
3. Remove dust bin and dispose of material in accordance with local regulations.
Caution: Dirty filters can be awkward to handle. Wear personal protective
equipment.
4.
While the filter is out, inspect the Jet-Pulse hose for cracks, splits, or
degrading. Conical end wear is normal. The hose should be approximately 7"
(175mm) long. Replace a hose that does not appear normal or which is worn to
less than 6" (150mm). See below!
5.
Install new filter.
