Airbrush Rockforce RF-SL150B, 0.3 mm nozzle, 6 ml capacity, side-feed

The Rockforce RF-SL150B airbrush is a precision side-feed tool designed for detailed painting tasks. Fitted with a 0.3 mm nozzle and a 6 ml side-mounted paint cup, it provides controlled atomization for fine lines, gradients and small-area coverage. The airbrush is intended for use with thinned paints and inks and works with standard airbrush compressors and fittings.

Advantages

The 0.3 mm nozzle delivers a balance between fine detail and moderate coverage, allowing crisp lines and controlled spray. The 6 ml side-feed cup offers convenient paint changes and good visibility of paint level while minimizing interruption during work. Side-feed configuration improves access to narrow areas and makes multi-layer masking and precision work easier. Compatible with common compressor setups and accessories, the tool supports a wide range of hobby and modelling workflows.

Suitable for

• Scale models and miniatures
• Hobby and craft detailing
• Touch-up painting and small repairs
• Stencilling and fine shading work
• Applying inks and thinned lacquers

Key specifications

• Nozzle diameter: 0.3 mm for fine to medium detail
• Paint cup capacity: 6 ml side-mounted reservoir
• Feed type: side-feed for improved maneuverability and visibility
• Material: metal airbrush body with precision needle and nozzle (metal construction for durability)
• Compatibility: works with standard airbrush compressors, hoses and fittings

How to use

Before use, ensure the paint is properly thinned to the manufacturer’s recommended viscosity for a 0.3 mm nozzle. Attach the airbrush to a compatible compressor and test spray on scrap material to adjust air pressure and paint flow. Hold the airbrush 10–20 cm from the surface for general coverage and move closer for finer lines. For detailed work, use short, controlled bursts and modulate trigger pressure to control paint volume. Clean the nozzle and needle after each session to prevent clogging and maintain consistent performance.

Usage recommendations

Use low-to-moderate air pressure suited to thinned paints (typically 15–30 psi / 1–2 bar depending on paint viscosity). Flush the cup and nozzle between colour changes and perform regular deep cleaning of the needle and nozzle to keep the 0.3 mm tip performing reliably. When working on small models, consider masking and staged thin coats rather than heavy single passes to avoid pooling and loss of detail.
