Operating in Dust-Heavy Environments
On construction or agricultural sites where airborne dust is unavoidable, the 25-micron microfibre media prevents abrasive particles from entering the hydraulic circuit. This helps reduce component scoring and extends the service life of pumps and motors.
Continuous-Duty Manufacturing
In factories running hydraulic presses or injection moulding machines around the clock, consistent filtration is critical. Installing the SPM-HYD-1666 ensures steady contaminant removal during long production runs, minimising unplanned downtime caused by fluid contamination.
Streamlined Fleet Maintenance
For operators managing multiple machines powered by Hydac hydraulics, this filter standardises spares inventory. Keeping a single aftermarket part number on the shelf simplifies reordering and reduces the risk of stocking mismatched elements across a mixed fleet.
Predictive Maintenance Scheduling
Planning filter changes at set intervals helps maintain hydraulic system health. The SPM-HYD-1666 allows you to schedule replacements based on hours or condition monitoring, confident that each service restores full-rated filtration without overspend.
Yes, the SPM-HYD-1666 is engineered to match Hydac OEM filter dimensions and flow requirements. It directly cross-references to Fai Filtri and Oxfil part numbers as well. Always verify your existing element’s height (170 mm), largest outer diameter (56 mm) and largest inner diameter (25.5 mm) against these measurements to confirm fitment.
The element features a 25-micron rating and is built with inorganic microfibre media. This synthetic material provides consistent particle retention at the stated micron level, supporting clean hydraulic fluid throughout the service interval.
Total height is 170 mm, largest outer diameter is 56 mm, and largest inner diameter is 25.5 mm. The flow direction is out-in, meaning fluid passes from the outside of the element to the inside, which is typical for many hydraulic return-line and pressure-filter applications.
It is manufactured using premium inorganic microfibre media and closely follows OEM design parameters, so you get dependable filtration without the premium price tag. Every SPM hydraulic filter is covered by a 30-day money-back guarantee and our price-beat promise.
The SPM-HYD-1666 is a drop-in replacement, so anyone familiar with basic hydraulic maintenance can install it. Always depressurise the system, follow the machine manufacturer’s filter-change guidelines, and properly dispose of the used element.
We provide worldwide shipping with full tracking on every order. You are protected by a 30-day money-back guarantee and a price-beat guarantee. Please contact our support team if you have any concerns after receiving your filter.
