Argo-Hytos FNL 1000 Low-Pressure In-Line Filter (High Performance)
The Argo-Hytos FNL 1000 is a large-capacity low-pressure in-line filter for hydraulic and lubrication pressure circuits operating at up to 40 bar. With a nominal flow of 555 l/min, it's built for high-volume systems where maintaining oil cleanliness is critical to uptime.
Star-shaped pleated EXAPOR®MAX 3 filter media delivers a large surface area, low pressure drop, and high dirt-holding capacity — extending service intervals and minimising maintenance costs. Clogging indicators (optical or electrical) are available to take the guesswork out of servicing.
