Urgent: What do the filter models FW4C and LPG-HE each represent?
Thread Content
Hello everyone, this is my first time at Haichuan, and I truly hope to learn from all of you experts. I have a rather urgent question right now: when choosing between the filter models FW4C and LPG-HE, what do these models mean?
I checked, and it’s not a standard model; it should be an internal model of the manufacturer
No relevant information found....
LPG refers to a straight-through backwash filter; the HE mentioned later is probably the manufacturer’s code. As for FW4C, it’s not clear what it means
Well, the medium suitable for use has been confirmed; it’s the factory-supplied basket filter with backwashing functionality
Mm-hmm, yes, it has been verified again based on the application medium; the factory-supplied basket filters and backwashing are used
