DATA REPORT™
Our report tells the condition of bag filters, and also
tells of any problems you might experience within your baghouse.
Computer generated photo included.
Your tests were performed on our unique
STEROPTIC VIDEO ANALYSIS (see photo supplement
report) which compares your bags to OEM specifications

OVERALL TEST RESULTS:
Does FrisbieFilter recommend you recondition your filter
bags? (YES)
|
Frisbie's Filter Service, Inc. Technical Data Report
Test Information
- TEST 1) LIGHT TEST (PASS) The
light test is performed with a machine projecting a concentrated beam
of light through the filter. This allows for a rigided inspection of
the scrim (fibers) both inside and out examining for deterioration and
wear.
- Pass Bag is acceptable to wash.
- Damage Bag has weak area(s) needing repair. This area will
be repaired after washing.
- Fail The scrim (fiber) is beyond repair. The bag must be
replaced.
Failure from premature deterioration and wear can be isolated to
the following areas:
- Defective cages
- Incorrect installation
- Weak fabri
- Cage oxidation
- Poor dustcake release
- TEST 2) MULLEN BURST TEST: (PASS)
Machine tested for strength of the fabric. This is a Mullen Burst Test.
The test will determine if the fabric will stand the test of time. Longevity
is important when considering the cost of down-time to replace a bag which
should never have been installed. An explanation of different permeability
results follows:
- Pass The strength of the bag is assured for a long life.
- Weak: Bag life may be shorten, test is below new standard.
- Fail The fabric of the bag is weak. The bag must not be
cleaned. The bag must be replaced
.
- TEST 3) PERMEABILITY:(35.0) NORMAL
This test simulates the bag in actual use in a bag house. Proper air
flow and filtration falls within a measurable range. An explanation
of the Permeability Test follows:
- 60 - 85 (cu ft/min) sq ft Low The fabric will not filter
properly and bleed through will result.
- 25 - 40 (cu ft/min) sq ft Normal
- 15 - 25 (cu ft/min) sq ft High Restriction is too high.
The soil will not come out of the fabric
.
- TEST 4) WEIGHT TEST Weight Difference
= (0.5)
Dustcake Release is important. The results of the Weight test will
determine if maintaince repair or maintance intervals need to be reviewed.
WEIGHT BEFORE - WEIGHT AFTER = WEIGHT DIFFERENCE.
If the WEIGHT DIFFERENCE is greater then 1.5 lbs
- Consider increasing changout cycle.
- Check pulse intervals in bag house.
- Check with bag Manufacturer for special coatings for better cake
release.
- TEST 5) pH BALANCE TEST (7.5)
NORMAL Testing for the final ph of the fabric is crictical to the shelf-life
of any fabric. Bags are tested during the process to insure that the
ph will not cause a premature life cycle.
- Low.....4.5 - 5.9
- Normal.. 6 - 8
- High....8.5 - 10.5
- TEST 6) ELASTICITY TEST (0.50)
When bags are laundered the fabric will pull together in the washing
process. This is normal. All bags are then checked on cages for proper
fit. As a added measure, this test pulls the bags taunt to determine
the amount of elasticity in the fabric. After installing the bag in
the bag house you will see that it is a proper fit. Normal range .25"
to 1.00"
- TEST 7) INSPECTION TEST REPAIR
NEEDED AT -TOP -MIDDLE OF BAG
The bag is checked from top to bottom. If normal repairs are needed, the
repairs are made at no extra charge. Normal repair of the fabric will
not degrade the funtion of the bag. The bag will funtion like normal.
There is no charge for normal repairs. An explanation of different Inspection
tests follows: Repair Not Needed: The bag does not need repair. Repair
Needed: The repair will not obstruct the normal function of the bag Replace:
The bag is beyond repair. Replace with new.
- TEST 8) PIGMENTATION YES This
is a visual inspection to check the bag for discoloration and staining.
YES: This has no effect on the air restriction or the life cycle of
the bad. Bag is Okay to use
- Test 9) CALIBRATION (0.090) PASS
Calibration shows thickness of fabric. This O.E.M test must be performed
at the factory before manufacturing of new bags occurs. We follow the
factory specification for thickness
PASS
0.060" - 0.090"
12 - 16 oz
PASS: 0.020"- 0.35
10 - 7 oz |
Bags will perform proper filtration. Important when determining
bags life-cycle |
FAIL
0.055" - 0.035
12-16 oz
FAIL: 0.014" - 0.019
10-7 oz |
You will not receive a full life-cycle. You can suspect poor filtration |
- Test 10) TENSILE (200 LB SQ FOOT)
NORMAL
Test for strength under POUND PER SQ FOOT. This test is performed by a
trained technician with a air over hydraulic cylinder pulling on the bag.
Gauge read out in PSF tells if the bag filter can handle the dirt load.
- Normal 160 - 375 LB.SQ.FT Meets FRISBIE'S FilTER standard
for holding dirt load. The result will be good filter life and no
tearing or leaking of foreign particles
- Fail 90 - 150 If bags are installed with low PSF rating
you run risk of bag tearing and leaking around tube sheet. You will
experience high maintenance cost and short bag life.
AREA 2: LOW PERFORMANCE BECAUSE OF OUT SIDE SOURCE
PROBLEM AREA(S) THAT OUR STEREOPTIC VIDEO ANALYZER HAS FOUND. BEFORE THE
BAGS ARE RECONDITIONED AND TO INSURE LONGER BAG LIFE, YOU WILL NEED TO LOOK
AT THIS AREA(S) AND MAKE ADJUSTMENTS. WE HAVE ENCLOSED A PICTURE OF THE
PROBLEM AREA. (see photo supplement) IF YOU ARE
HAVING PROBLEMS WITH YOUR BAGHOUSE, PLEASE CALL OUR LAB. WE OFFER OTHER
DETAIL TESTING THAT CAN HELP YOU IN BAG PERFOMANCE.
AREA 5 FAILURE BECAUSE OF REMOVAL PROBLEM
AREA(S) THAT OUR STEREOPTIC PICTURE ANALYZER HAS FOUND. BEFORE THE BAGS
ARE RECONDITIONED AND TO INSURE LONGER BAG LIFE, YOU WILL NEED TO LOOK
AT THIS AREA(S) AND MAKE ADJUSTMENTS. WE HAVE ENCLOSED A PICTURE OF THE
PROBLEM AREA. (see photo supplement) IF YOU
ARE HAVING PROBLEMS WITH YOUR BAGHOUSE, PLEASE CALL OUR LAB. WE OFFER
OTHER DETAIL TESTING THAT CAN HELP YOU IN BAG PERFOMANCE. Comments: 194
BAGS HAD TO BE PATCHED 10 SNAP BANDS NEED SEWING REPAIR. 3 BAGS WERE SHORT.
OVERALL TEST RESULT: DOES FRISBIE'S RECOMMEND YOU RECONDITION YOUR BAG
FILTERS? (YES) FRISBIE'S REQUESTS THAT YOU SAMPLE EACH TEST BAG AFTER
RECONDITIONING TO ENSURE PROPER FIT ACCORDING TO THE CUSTOMER SPECIFICATIONS
BEFORE RECONDITIONING THE FULL SET.
