Hydac OLF Offline Filters: Advanced Protection for Your Hydraulic System
The Hydac OLF (15/30/45/60) offline filters are designed to provide robust and reliable filtration in stationary applications with large oil volumes in hydraulic and lubrication systems.
🔍 What are offline filters used for?
Unlike inline filters installed directly in the main circuit, offline filters operate in a separate loop. They draw oil from the reservoir, filter it, and return it clean—without interrupting the system’s main operation. This delivers:
-
Effective removal of solid particles and contaminants 🛑
-
Extended service life of critical components (pumps, valves, actuators)
-
Increased fluid stability and hydraulic system efficiency
🛠 Key Features of the OLF 15/30/45/60 Series

Heavy-duty design for stationary use
-
Filter housings with integrated motor-pump units (flow rates: 5, 10, 15, and 20 gpm)
-
High-performance N15DM filter elements (2 µm filtration rating)
-
Operating temperature range: 15 °F to 175 °F (–9 °C to +80 °C)
-
High capacity for large oil volumes and efficient contaminant removal
