Maintaining fluid cleanliness is essential for the longevity and performance of hydraulic and lubrication systems. Fluid conditioning through efficient filtration is crucial to removing contaminants such as solid particles and water, which can cause component wear, system failures, and increased maintenance costs. HYDAC’s offline filters provide reliable solutions for ensuring superior fluid conditioning and system efficiency.
HYDAC offers a variety of offline filtration solutions to meet different industrial needs:

OLF 15/30/45/60 Series: These robust units are designed for stationary applications in large hydraulic and lubrication systems. They feature Dimicron® elements for superior contamination retention and environmentally friendly disposal. With housing capacities of up to 78 liters and an operating pressure of up to 6 bar, they extend component service life, increase machine availability, and reduce maintenance intervals.

OLF 5 Series: Compact and stationary, the OLF 5 is ideal for fine filtration of hydraulic and lubricating oils in bypass flow. It offers optional integrated fluid sensor technology to monitor contamination levels, water saturation, and temperature in real-time. With a flow rate of up to 15 l/min and an operating pressure of up to 4.5 bar, this unit enhances reliability and extends oil change intervals.

The MFU (Mobile Filtration Unit) is a portable solution for maintaining fluid cleanliness across multiple systems. Designed for flexibility, it allows on-site filtration of hydraulic and lubrication oils, ensuring optimal fluid quality wherever needed.
