These suction units are designed to be connected directly to the vacuum pump
through the flanged manifold. The suction units prevent foreign bodies (with
dimensions greater than the degree of filtration of the filtering cartridge) from
entering inside the pumping system.
The suction units are available in three versions:
- Filter suction unit LC420-RV520 (code 18521 2L4 B0) made of aluminium;
- Filter suction unit LC300-RV360 (code 18521 CNG B0) made of aluminium;
- Filter suction unit PN-R (code 18521 9N7 B0) made of aluminium;
All versions are equipped with an aluminium filter housing (having a stainless
steel cartridge), a side flanged aluminium manifold and a rear steel flange.
