50000 - ACF-50 Handheld Spray System - Model 50000 – Turns ACF-50 Into a Dense Fog

The ACF-50 50000 spray system is engineered to apply ACF-50 anti-corrosion treatment to aircraft and other vehicles efficiently and evenly. It enables technicians to atomize the solution into hard-to-reach areas using a variety of interchangeable wands. The system is commonly used for both preventative corrosion protection and post-maintenance treatments on fixed-wing aircraft, helicopters, and other metal-intensive platforms.

While both systems are used for applying ACF-50, the 50000 spray system is a handheld unit with a built-in 32 oz. reservoir and operates using shop air at 50 to 90 PSI. In contrast, the 50003 pump system is larger, designed for shop use with a 3.78-liter container and delivers product via a siphon mechanism. The 50000 is more portable and ideal for targeted applications or fieldwork, while the 50003 is suited for extended or high-volume spraying jobs.

The spray system includes a durable spray gun, multiple interchangeable extension wands, and a 32-oz. fluid container. It comes with seven distinct lances/wands, each designed for specific application scenarios such as wide-area misting or precision application in confined spaces. A durable carrying case is also provided for the storage and transport of the complete system.

The ACF-50 50000 spray system requires a clean, dry compressed air source delivering between 50 and 90 PSI. Optimal results are typically achieved at around 70 PSI. Using air that exceeds the recommended pressure can damage the internal components of the spray gun, while insufficient pressure may reduce atomization and result in poor spray coverage.

The system is specifically designed and calibrated for ACF-50, a nonflammable, aircraft-approved corrosion inhibitor. While it may be physically compatible with other light fluids, using unapproved chemicals could degrade seals, clog the fine misting nozzles, or lead to suboptimal spray performance. For best results and to ensure long-term durability, it is recommended to use only ACF-50 as directed by the manufacturer.

After each use, the gun and wands should be cleaned using a solvent compatible with ACF-50, such as mineral spirits or a mild degreaser. Flush the system by spraying a small amount of solvent through each wand and nozzle to prevent buildup. Cleaning is essential to prevent clogs and ensure the system remains operational for future treatments.

Routine maintenance includes cleaning after each use, inspecting the wands for obstructions, and checking all fittings for air leaks or wear. The O-rings and seals in the spray gun should be lubricated occasionally with a non-reactive lubricant. Store the unit in its provided carrying case to protect against damage and contamination.

Absolutely! The ACF-50 50000 system is widely used on motorcycles, marine vessels, drones, and vehicles with complex metal structures. It’s ideal for reaching corrosion-prone areas like wiring harnesses, battery terminals, hinges, and seams. However, make sure to follow all safety and application instructions, especially when working around sensitive electronics.

Yes, the unit is safe for indoor use, provided there is adequate ventilation. ACF-50 produces minimal odor and does not contain flammable solvents, but mist overspray should be avoided around sensitive surfaces or instruments. Protective eyewear and gloves are recommended during use to avoid direct contact with the product.

The set includes seven specialized wands, each designed for a specific purpose:

• A 6" 360° lance for fogging enclosed areas
• A 90° lance for hard-to-reach spots
• A flex wand for maneuvering around bends
• A fan-pattern lance for wide-area coverage
  

These wands allow for targeted, efficient application.

While the spray gun itself doesn’t require FAA certification, ACF-50 fluid is approved under MIL-SPEC MIL-C-81309E, Type II, and is widely accepted for use in both civil and military aircraft. The 50000 system is simply the delivery tool for applying this approved corrosion inhibitor and is used in compliance with aviation maintenance practices globally.

A 32 oz. fill can cover approximately 300–500 square feet, depending on the application method, surface material, and level of atomization used. Fine misting with proper wand selection allows for efficient use and minimal overspray. This makes the system suitable for complete corrosion treatment on small to midsize aircraft or focused spot treatment on larger platforms.

This is not recommended. For best results and to prevent clogging or seal degradation, the reservoir should be emptied and flushed with solvent after each use. Leaving ACF-50 in the gun may lead to buildup in the nozzles and reduce the unit’s spray efficiency over time.
