LIQUI MOLY AC System Cleaner Gun

LIQUI MOLY AC System Cleaner Gun (4090) | Professional HVAC System Deep Cleaning

Achieve professional-grade AC cleaning with the LIQUI MOLY Cleaner Gun (SKU 4090). Features a flexible probe, ball-shaped spray, and 1.2L tank for thorough evaporator cleaning and removal of odors. Ideal for workshops and pro use.

The LIQUI MOLY Air-Conditioner System Cleaner Gun (SKU 4090) is a professional-grade application tool specifically engineered for the deep and hygienic cleaning of automotive, commercial vehicle, bus, and industrial air conditioning systems. This specialized spray gun works in conjunction with LIQUI MOLY's A/C System Cleaner Fluid (such as Active-2P/Item 20001 or equivalent) to deliver the cleaner directly onto the evaporator surface and into the ventilation ducts. The core of its design is the flexible probe which is tipped with a unique ball-shaped spray jet (360° nozzle). This allows technicians to navigate complex ductwork and directly target the evaporator fins, ensuring the cleaning fluid is distributed evenly and thoroughly over the entire surface. This crucial step ensures the effective removal of mold, bacteria, fungi, and dirt deposits—the primary causes of musty odors and allergens. The gun features an approximately 1.2 liter (0.32 gallon) tank connected via a quick connector, which provides excellent handling and mobility during the cleaning process. This system ensures a more comprehensive cleaning compared to standard spray-can applications, leading to restored AC performance, better air quality, and long-lasting freshness in the vehicle's cabin. This is an essential piece of equipment for any professional workshop or serious automotive enthusiast.

Best Uses

1. Professional Automotive Workshops & Garages: Primary tool for offering a premium, thorough A/C system cleaning service to customers.
2. Commercial Fleets and Transit Maintenance: For the regular, hygienic cleaning of air conditioning systems in buses, trucks, and other commercial vehicles.
3. Industrial/Large HVAC Systems: Suitable for cleaning industrial or large domestic air conditioning evaporators where precise, directed application is required.
4. Hygienic Maintenance: Essential for removing biological contaminants (mold, bacteria, fungi) that cause unpleasant odors and pose health risks.
5. Restoring AC Performance: Used to clean dirt and deposits off the evaporator fins, which restores cooling efficiency and improves airflow.

Features

1. Flexible Application Probe: A long, flexible probe designed to navigate complex air ducts and reach the hard-to-access evaporator core.
2. Ball-Shaped Spray Jet (360° Nozzle): Delivers a directed, omni-directional spray pattern for comprehensive and uniform saturation of the entire evaporator surface.
3. 1.2 Liter (0.32 gal) Tank: Provides an ample fluid capacity for cleaning most vehicle A/C systems in a single filling, enhancing efficiency.
4. Quick Connector: Features a quick-release coupling for fast, secure, and hassle-free attachment of the gun to the cleaner fluid hose/tank.
5. Compressed Air Operation: Designed to be operated with compressed air (sold separately) to ensure powerful application and deep penetration of the cleaning fluid into the evaporator fins.

Benefits

1. Maximum Cleaning Effectiveness: Ensures the cleaning fluid reaches and saturates the entire evaporator, which is not possible with simple aerosol sprays.
2. Eliminates Foul Odors: Thoroughly flushes out mold, bacteria, and dirt deposits, permanently removing musty smells instead of just masking them.
3. Improves Air Quality: Removes allergens and contaminants, leading to a healthier, fresher, and more hygienic environment in the vehicle cabin.
4. Restores AC Efficiency: By cleaning dirt and deposits from the evaporator fins, it helps restore the system's optimal heat transfer and cooling performance.
5. Professional and Targeted Application: Provides workshop-grade results and simplifies the cleaning procedure for technicians, offering an efficient, non-disassembly-required solution.
