Key Features
- Genuine OEM Filtration Media — Paper filter element manufactured to Multiquip's exact flow-rate and particulate-capture specifications for the hydraulic return circuit on RAMMAX rollers.
- Direct-Fit Replacement — Engineered to drop into the existing filter housing on compatible units with no rework or adapter hardware required.
- Confirmed Fitment — Verified for RW1403HF, RW1404, and RW1404MR rollers, including RW1404MR machines from S/N 326075 and up.
- Hydraulic System Protection — A clean return filter traps wear particles before they re-enter the hydraulic reservoir, preventing pump and valve wear that leads to costly component failures.
- Correct Part, First Time — Ordering by Multiquip part number 51665 eliminates guesswork and ensures the filter element matches the housing geometry and pressure rating of your machine's return line.
The paper return filter sits in the hydraulic return line between the working components and the reservoir, capturing contaminants — such as metal particles and debris — before clean fluid cycles back into the system. On RAMMAX rollers like the RW1404 and RW1403HF, maintaining a clean return filter is critical because any bypass of contaminated fluid accelerates wear on the hydraulic pump, control valves, and drive motors. A clogged or deteriorated filter element can cause sluggish drum response, overheating, or hydraulic pressure loss, making timely replacement an essential part of routine roller service.
