Festo – 369589 – ILR‑03 Pneumatic Pressure Regulator (5–8 bar Inlet → 5 bar Out)

The Festo ILR‑03 (P/N 369589) is a compact block-type pneumatic pressure regulator designed to deliver stable downstream pressure in compressed-air systems. It reduces inlet pressure (up to 8 bar) to a fixed 5 bar output, making it ideal for modular system integration on valve terminals or manifolds.
