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.

Key Features:

Model: ILR‑03 (Festo 369589)
Function: Pneumatic pressure regulator, block-mounted type
Inlet Pressure (P₁): Maximum 8 bar
Outlet Pressure (P₂): Regulated to approximately 5 bar
Flow Characteristics: Nominal flow ~420 L/min (I → II) with minimal leakage (~5 L/h)
Medium: Filtered compressed air (≤ 40 µm particle size)
Design: Via piston regulator; integrated non-return valve; modular screw-in mounting on sub-base
Temperature Range: –10 °C to +60 °C (ambient & medium)
Construction: Compact dimensions (approx. 26×39 mm), ~30–50 g weight
Approval Standards: CE marked; compliant with Festo engineering specifications
