Product Description

Cold starts, load spikes, and high-vibration applications necessitate a Return Filter that refuses to fail. The LI3421 filter is engineered for exactly these punishing scenarios, offering superior durability for FISPA machinery. When standard components risk media migration or collapse, this industrial-strength element holds its shape and stable running, certifying your circuit remains protected from sudden contamination events.

We achieve this resilience by utilizing a specialized Cellulose that operates effectively at a 25μm@β2 efficiency, regardless of fluid temperature or frequent pulses. Combined with its exact OD70xID29xH85mm architecture, the LI3421 filter fits tightly into the manifold block. This provides engineers with the assurance that their hydraulic oil is being filtered continuously, even in the most hostile environments.
