Karcher 9.990-879.0 Accessory Kit for Liquid DN50

The Kärcher Liquid/Solid Accessory Kit Expert DN50 (9.990-879.0) is a professional accessory set developed for compatible Kärcher industrial vacuum cleaners requiring a robust DN 50 suction system for the recovery of liquids and wet contamination. Supplied as a coordinated set of genuine Kärcher components, it provides the essential hose, handle and nozzle equipment needed to turn a compatible industrial vacuum into a versatile hand-operated cleaning system for demanding workshop, manufacturing and industrial maintenance applications.

At the heart of the kit is a 3-metre polyurethane (PU) suction hose (9.989-619.0). The generous hose length provides operators with a practical working radius around machinery, production equipment, tanks and other obstacles without continually repositioning the vacuum cleaner. PU construction is particularly appropriate for professional environments where flexibility, durability and resistance to everyday mechanical wear are important.

The kit also incorporates the Kärcher DN 50 curved handle (9.977-678.0). Kärcher specifies this component as an electroconductive stainless-steel handle with a 45° bend and DN 50 inner cone, providing a strong and comfortable connection between the suction hose and cleaning nozzle. Its curved configuration improves handling when working at floor level or around industrial equipment, while its robust construction is intended for frequent professional use.

Two different nozzles are supplied to increase versatility. The standard nozzle (9.988-402.0) is intended for targeted suction and accessing smaller areas, while the 120 mm surface nozzle (9.988-119.0) provides a wider working area for recovering liquids from floors and other accessible surfaces. Switching between the two allows operators to tackle localised spills as well as broader areas of wet contamination without requiring a completely separate accessory system.

The kit's DN 50 nominal diameter is particularly important in industrial vacuum applications. The larger suction pathway is designed to complement Kärcher's high-capacity IVR, IVR-L and IVS industrial vacuum systems, allowing substantial airflow through the accessory system and providing a practical solution for demanding liquid-recovery work. Kärcher lists the kit for an extensive range of its professional industrial vacuums rather than limiting it to a single machine family.

For facilities that regularly deal with leaks, spills, process liquids and wet contamination, having a dedicated liquid accessory kit can considerably improve the versatility of an existing industrial vacuum. Typical applications include engineering workshops, production facilities, maintenance departments, manufacturing plants and industrial cleaning operations, particularly where operators need to move quickly between concentrated suction work and larger surface-cleaning tasks.

As a genuine Kärcher Expert accessory set, the individual components have been selected to work together as a complete DN 50 system. Kärcher specifies a total packaged weight of approximately 5.5 kg, making this a substantial professional accessory package designed for repeated industrial use.
