Replacement Cartridge
This is the part a customer replaces, so it decides whether a filtration programme is profitable after the first sale. We build the membrane ourselves, which is why the element can be specified by polymer rather than bought in.
LX-A1 is the universal 10-inch element at Φ70 × 254 mm. LX-A2 is the same format built for OEM programmes, with custom flow rates and laser or inkjet end-cap branding. LX-A3 is the 1812 size at Φ56 mm for compact housings.
All three are available in PS, PVDF or PES and operate between 4 and 45 °C. Elements ship vacuum-sealed with food-grade silicone O-rings so the hydrophilic fibers do not dry out.
