Flushing the Filter

For highest performance and robustness, the 1290 Infinity Quaternary
Pump uses 3 solvent filters:
1 Solvent inlet filter, 20 µm pore size (5041- 2168) as part of Bottle Head
2 An outlet filter (average pore size 5 µm; Outlet filter 1290 Infinity
70
Assembly (G4220- 60007) have a large pore size of about 20 µm and
filter out particles before they reach the pump.
Solvent inlet filter
Quaternary Pump (G4204- 60004)) between pump head and pressure
sensor filters out particles which may be created in the pump by wear
of piston or wash seals.
This filter can be replaced as required.
