Karcher Cup Foam Lance Basic 3 900–2500 L/h 4.112-055.0

Karcher Cup Foam Lance Basic 3 (900-2500 L/h)

Maximize detergent efficiency and achieve superior vehicle cleaning results with the Karcher Cup Foam Lance Basic 3 (4.112-055.0). Standard low-pressure chemical injectors often produce a weak, runny soap mixture that slides off vertical surfaces immediately, providing zero dwell time. This professional-grade high-pressure foam lance completely aerates the cleaning chemical, projecting a thick, dense layer of clinging foam. This allows commercial degreasers and traffic film removers to dwell on the surface, actively dissolving severe road grime before the high-pressure rinse phase.

Engineered explicitly for Karcher commercial pressure washers operating with a water flow rate between 900 and 2500 Litres per hour (L/h), this premium attachment is constructed around a highly durable, heavy-duty brass base body. A critical feature of the Basic 3 is its highly accurate, three-stage dosing system (1%, 2%, 4%), controlled via an integrated selector plate. This prevents accidental adjustment during operation and can reduce chemical consumption by up to 50%. Complete with a 1-Litre ergonomic detergent bottle and the Karcher EASY!Lock connection system, this commercial foam cannon is an essential tool for automotive detailing, fleet washing, and industrial sanitation.

Ideal For:

• Commercial Vehicle & Fleet Washing: The thick foam clings to the vertical sides of large trucks, trailers, and vans, dramatically increasing chemical dwell time to melt heavy road film.
• Automotive Detailing Bays: Essential for applying high-quality 'snow foam' as a pre-wash to safely lift abrasive grit off vehicle paintwork without scratching.
• Industrial Sanitation: Highly effective for rapidly applying foaming degreasers or sanitizers across large factory floors, tiled abattoirs, and food processing areas.

Key Features & Operational Benefits:

• Extreme Chemical Economy: The optimized aeration chamber creates massive volumes of foam from minimal chemical. When paired with high-quality detergents, it reduces chemical usage by up to 50%.
• 3-Stage Integrated Dosing: The selector plate allows operators to lock the chemical draw rate accurately at 1%, 2%, or 4%, preventing accidental knocks that lead to severe chemical wastage.
• Heavy-Duty Brass Body: Forged from premium commercial brass to withstand the massive 300 Bar maximum pressure rating and resist corrosion from harsh alkaline degreasers.
• EASY!Lock Connection: Features Karcher’s proprietary quick-thread system, allowing operators to attach the foam lance securely to the spray gun with a single 360-degree turn.
