09-04083 - ACF-50 Standard Pump System - Model 50003 – Turns ACF-50 Into a Dense Fog

The ACF-50 Pump System 50003 is designed to apply ACF-50 corrosion prevention compound efficiently to aircraft surfaces and internal areas. It delivers a fine atomized mist for penetrating hard-to-reach areas, including lap seams, joints, and around rivets. This ensures thorough coverage of both accessible and inaccessible metal surfaces, making it ideal for ongoing corrosion control in aviation environments.

Using the wand system included with the 50003 kit, technicians can direct ACF-50 into confined or hidden spaces such as leading edges, floor beams, or fuselage cavities. These wands produce an atomized spray that coats internal surfaces evenly without needing disassembly. This is particularly useful for long-term corrosion prevention in areas prone to moisture entrapment.

The pump system is suitable for both fixed-wing and rotary-wing aircraft, including general aviation planes, helicopters, and larger commercial airframes. OEMs, MROs, and individual aircraft owners use it to protect various structural components, avionics housings, landing gear, and electrical connectors from corrosion. Its versatility makes it a go-to system for corrosion control across multiple aircraft platforms.

The kit typically includes a 1-gallon refillable stainless steel tank, 60 PSI pump assembly, 15-foot hose, various quick-disconnect spray wands, and a control valve with trigger. Among the included applicators are 45-degree and 90-degree spray tips, a 360-degree fogging wand, and a flat fan nozzle for external surfaces. This range of tools provides comprehensive coverage for targeted and wide-area applications.

The ACF-50 Pump System 50003 is optimized specifically for use with ACF-50, which has a low viscosity and is designed for atomization. While technically it could be used with similar light oils or corrosion inhibitors, doing so may void warranties or reduce performance. Always refer to the user manual and manufacturer recommendations when considering alternative fluids.

For most aircraft, ACF-50 should be reapplied approximately every 12 to 24 months, depending on usage, environmental exposure, and maintenance cycles. Heavily used or coastal-based aircraft may require more frequent treatment. The pump system allows for precise application, making periodic re-treatment efficient and cost-effective.

Yes, the 50003 system includes a flat fan nozzle that allows for even, misted coverage across exterior panels. This is ideal for treating gear wells, wing roots, and access panels where moisture tends to collect. The atomized spray does not leave a heavy residue and will not attract dirt, making it safe for use on painted and polished surfaces.

No. ACF-50 is nonconductive, nonflammable, and safe for aircraft paint, plastics, insulation, and wiring. It penetrates and displaces moisture without softening or degrading electrical insulation, and it will not harm composite materials or coatings. Its dielectric properties make it ideal for sensitive avionics environments.

The stainless steel tank is designed for up to 60 PSI of compressed air. This allows for effective atomization of ACF-50 through the specialized wands and spray tips. However, to maintain safety and optimal performance, it is important not to exceed the recommended pressure.

Yes. After each use, it is recommended to flush the system with a light solvent or clean mineral oil to prevent residue buildup. The stainless steel components and hoses are corrosion-resistant, and the quick-disconnect fittings make cleaning and maintenance simple. Keeping the wands and nozzles clean ensures consistent spray quality over time.

Absolutely! The pump system is designed for shop or hangar use where access to a compressor is available. It is quiet, compact, and safe to use indoors since ACF-50 is nontoxic, low-odor, and environmentally friendly. Proper ventilation is always encouraged, especially when applying inside fuselage sections or enclosed areas.

The longevity of a gallon depends on application technique and aircraft size, but typically, one gallon can treat two to three small general aviation aircraft or one mid-size airframe. The atomizing wands ensure minimal overspray, maximizing product efficiency. For larger fleets, purchasing ACF-50 in bulk and using this pump system offers cost savings and consistent protection.
