FASTEK Osmonics Membrane
I’m trying to replace a filter with the following printed on the outside:
S/N 8436 – 8905
The Osmonics TFM-18 (TLC-15) is same as TLC-18.
Just a different label.
It’s a standard size RO Membrane
A 1.50 – B 11.75 – C 10.00 – D 0.875 – E 0.678 (1 inch = 25.4 mm)
NOTE: The original Fastek S1312-18S TLC-18 came with a SEALED membrane housing.
If the membrane (housing) you have is sealed, a NEW Membrane WITH housing is needed. Select Model TLC-15MOD-G
How the Membrane System Works
The spiral membrane is constructed of one or more membrane envelopes wound around a perforated central tube. The permeate passes through the membrane into the envelope and spirals inward to the central tube for collection.
Hope this helps.
