Hand-Push Cold Spray Single / Double Gun Machine

Model: RN-100S

The RN-100S is the single / double gun upgrade of the RN-100. It keeps the same gasoline-engine driven high-pressure airless cold spray technology, but adds a dual-gun option that lays two lines at once or widens a single line — substantially raising on-site efficiency for highways, municipal roads, parking lots, airports, and residential areas.

An engine-driven diaphragm pump builds high pressure and pushes the coating evenly through the gun(s), forming clear, full, uniformly thick lines. Guns are quick to detach and swap, nozzles control line width, and limit baffles keep edges burr-free. The hand-push chassis steers and positions easily, making the RN-100S a strong fit for both professional crews and new contractors scaling up.

With a maximum spray output of 10 L/min (vs. 4.2 L/min on the RN-100), a 6.5 HP gasoline engine, CE certification, and an MOQ of just 1 unit, the RN-100S is the higher-throughput choice for large or time-critical projects.

Key Features

• Single / double gun selectable — dual gun lays two lines or a wider single line, boosting efficiency
• High-pressure airless spraying — clear, full lines with strong adhesion and uniform thickness
• 6.5 HP gasoline engine — powerful, no external power needed, standalone outdoor operation
• Max spray output 10 L/min — major step up from the 4.2 L/min RN-100
• Detachable guns + limit baffle — clean edges, no burrs, flexible steering
• Adjustable width — 50–500 mm, fits solid/dashed lines, arrows, text, zebra crossings
• CE certified — meets international export safety requirements
• Low MOQ — 1 unit, ideal for trial and small-batch orders
