pertaining to aviation filtration.
23. Can you convert a filter/separator to a monitor unit?
Yes. However, if the system pressure can exceed
115 psi, some type of surge suppressor would need to be installed
upstream. Consideration should be given to relieve high-pressure
build up.
24. Which monitor cartridges would you use when converting a filter/separator
and why?
Generally you would use the FGI series monitor
elements. There are several (good) explanations for using this series.
Here are a few of the more common reasons. First, all coalescer
separator units have more coalescer stools than separators. Therefore,
you would be able to achieve the flow rate that you are looking
for. In some instances you could actually increase the flow of the
vessel. Second, if again the flow can be met with either, you will
find that the ones most readily available will be the FGI series.
25. Is the delta P gauge on a clay treater actually telling you
anything?
Not really. This is a common misconception.
The only true way to tell if the clay is working is to take a MSEP
test. This test will be taken on the inlet and the outlet and compared.
The reading from the outlet should be higher. A good quality fuel
has a reading of 85 or better. The closer you get to 100 the better
the fuel quality. If the fuel going in is 80 and the outlet is 80
or less, you would need to change out the clay.
26. How many pounds of solids does our MP series filter element
hold?
Up to 3-5 pounds per 14" length dependent
upon the micron rating and type of solids present.
27. With AVGAS, can you flow more through the same filter/separator?
Yes. Approximately 20% more through the same
unit.
28. What is the recommended sealing torque on screw base cartridges?
30 lbs. Ft.
29. What is the mesh size and micron rating of Facet’s Synthetic
separator?
50 micron, 267 mesh.
30. What are the benefits of Facet’s CIF Cartridge?
No metal components, less expensive while
maintaining high efficiency of M Series elements and
reduced disposal volume and cost.
31. How much water can monitors absorb?
>>FGI 614 holds 800 milliliters
>>FGO 614 holds 925 milliliters
>>FG 230 holds 170 milliliters
32. Does the size of the water droplets indicate the coalescing
efficiency?
Downstream: Yes, the bigger the drops the
more the fall. Saves Separator from having to do anything.
33. How is the gallon per minute of the coalescer calculated?
Flow per linear inch which is based on EI
test (Jet Fuel).
34. Can our immersion heaters be wired for a signal light?
Yes.
35. Which cartridges should be used in converting a F/S to a monitor?
The appropriate lengths can be used on either
the coalescer stools or separator stools. The FG-O monitor must
be installed on the separator stools and the FG-I monitor must be
installed on the coalescer stools unless the flow is reversed.
36. Why are F/S being modified to use monitors?
To increase flow rate, less expensive, no
single element test, no water detection sensor needed and assures
dry fuel. Fail safe feature.
37. What are certificates of similarity?
To provide certificate of test data in similar
type vessels using flow rates that determine the correct amount
of coalescers and separators. Upgrading an older vessel to EI 1581
current edition or changing from competitor vessel to Facet.
38. What are Monitor Certifications?
Monitor Certificates are designed to document
that the element and vessel configuration is capable of meeting
EI 1583 performance standards.
39. Are Material Safety Data Sheets (MSDS) required for the products
manufactured by Facet?
Items manufactured by Facet are considered
"articles" by definition of the regulations and therefore
do not need MSDS sheets.
40. What is the correct procedure for draining the sump on a coalescer
separator?
Per ATA-103 guidelines, drain fuel at maximum
practical flow into a suitable container. The vessel must be pressurized,
but fuel does not have to be flowing.
