Original MANN-FILTER U 620/4 y KIT - Urea filter – For trucks

Product Overview

The MANN‑FILTER U 620/4 y KIT – Urea Filter for Trucks is a high‑performance component designed to integrate seamlessly into diesel engines equipped with Selective Catalytic Reduction (SCR) systems. It captures and stores urea (AdBlue) in a dedicated reservoir, ensuring that the vehicle’s emissions control system operates at peak efficiency.

Key Features

• Optimised Flow Path: Engineered to minimise pressure drop while maintaining maximum urea delivery to the SCR catalyst.
• Durable Construction: Made from corrosion‑resistant materials that withstand the harsh operating environment of heavy‑duty trucks.
• Compact Design: Fits within standard engine bay layouts, reducing the need for extensive modifications.
• Easy Installation: Comes with all necessary mounting hardware and a gasket set to ensure a leak‑free seal.
• Compatibility: Designed for a wide range of MAN, Neoplan, Van Hool, Vison, DAF, and Otokar models that use the U 620/4 SCR system.

Technical Specifications

Installation Guide

1. Preparation: Ensure the engine bay is clean and dry. Verify that the existing urea reservoir housing matches the U 620/4 specifications.
2. Mounting: Align the filter with the mounting flange. Secure using the supplied bolts, tightening to the manufacturer’s torque specification (typically 12 Nm).
3. Sealing: Apply a thin layer of compatible sealant around the gasket area before final tightening.
4. Connection: Attach the urea inlet and outlet hoses. Use hose clamps rated for 200 °C to prevent leaks.
5. Testing: After installation, start the engine and monitor the urea pressure gauge. Confirm that there are no abnormal pressure spikes or drops.

Performance Benefits

• Reduced NOx Emissions: By delivering precise amounts of urea to the SCR catalyst, the filter helps maintain NOx levels below regulatory limits.
• Extended Catalyst Life: Consistent urea flow prevents catalyst fouling and prolongs its operational lifespan.
• Fuel Efficiency: Proper SCR function allows engines to run at optimal combustion settings, improving fuel economy.
• Reliability: The robust construction resists corrosion from acidic urea solutions, ensuring long‑term reliability.

Compatibility Matrix

The U 620/4 y KIT is engineered for a broad spectrum of heavy‑duty vehicles. Below are representative models that accept this filter:

• MAN: TGS, TGA, TGX, TGM, TGL series; LION S Regio; NM 6.9 (1990‑1993); NM 4.58 (1992‑1997)
