1. What is the operational life expectancy of the Teflon® and
Synthetic cartridge?
Facet Teflon® & Synthetic separator
cartridges are cleanable and reusable. They should be inspected
and tested before reusing. Cartridge service life should not be
extended beyond 5 years. Follow Facet cleaning procedures for Teflon
and Synthetic cartridges.
2. What is the shelf life expectancy of the Facet cartridges?
Most elements are a minimum of five years
if sealed and in temperature controlled environment. Monitors should
be installed within 2 years of shipment from Facet stock.
3. When do I changeout my filter/separator coalescer?
A. Coalescer elements must be replaced
when:
>>1. Filter Membrane (Milipore®) Test indicates elements
are not performing (Refer to Section 3).
>>2. Differential pressure exceeds 15 psi or there is a sudden
drop in differential pressure.
>>3. Continuous sump samples indicate surfactants, microbial
or solid contaminants.
>>4. 12-month service life has expired and approved extension
procedure is not accomplished.
>>5. Free water detection test indicates elements are not
performing (Ref. Section 3-3).
 4.
Is there a minimum flow rate for filter, filter/separators?
Operating a coalescer separator at less than
25% of rated flow, along with extended periods of inactivity, can
increase the risk for microbiological growth on the elements due
to free water not being released from the coalescer.
5. What is the typical clean differential pressure drop?
>>Filter/separators
2-4 psid clean at ambient temp.
>>Micronic Filters .5-4 psid clean at ambient temp.
>>2" Monitors 6-7 psid clean at ambient temp.
>>6" Monitors 3-4 psid clean at ambient temp.
6. Typical element change-out recommendations at maximum rated flow.
>>Filter/Separators 15 psi
>>Monitors 15 psi
>>Micronics 15 psi
>>“HP” 15 psi
>>Clays Based on MSEP test
7. What is the rupture pressure for each element?
>>Filter/Separators 75 psi
>>Monitors 174 psi
>>Micronics 75 psi
>>“HP” 15 psi
>>Clays N/A
8. What is the purpose of the Slug valve?
The slug valve stops the flow of product when
excessive water is collected in the coalescer/separator sump. It
works in conjunction with the float control valve. The slug can
also be furnished with rate of flow control which is used to control
flow through the coalescer/separator and with a check valve feature
to prevent back-flow.
