SURTEC NTS423

The SURTEC NTS423 sits at the top of the mist duster line for outright power. Its 72.3cc 2-stroke engine produces a rated output of 3.0kW (4.1hp) and drives a maximum air flow of 1300m³/h through a fine droplet misting system, pushing a horizontal reach of 15 meters across the crop. For tall tree crops, dense bush rows, and wide plantation blocks, that combination of engine muscle and droplet quality is what separates a powered backpack sprayer that finishes the block on schedule from one that leaves gaps in the canopy.

The fine droplet system is the working heart of the machine. By shearing liquid into small, uniform droplets and carrying them on high-speed airflow, the NTS423 achieves wide and uniform coverage with lower chemical consumption per hectare — more of what is sprayed lands where it is needed, and less settles on the ground or drifts past the target. The 12L container is deliberately sized for this working method: a full load of correctly concentrated mix, carried at 11.5kg net weight, keeps the operator moving without the shoulder strain of oversized tanks.

As a backpack pesticide sprayer for professional programs, the NTS423 handles insecticide, fungicide, and foliar fertilizer work across orchards, field crops, and greenhouse operations. The float-type carburetor meters fuel steadily through long full-throttle runs, and a 1.4L fuel tank matches tank-to-tank endurance to the chemical load, so fuel and mix run down together instead of stranding half a tank of chemical at the end of a row.

Durability is engineered into the engine architecture. The cylinder is available with two plating options — ceramic-plated for superior wear resistance and better heat dissipation, or chrome-plated for proven durability at a cost-effective price point — letting buyers match the build to their climate, duty cycle, and budget. Complete engine assemblies, from crankshafts and pistons to ignition coils and mufflers, are produced to strict tolerances for efficient combustion and reduced emissions, and robust starter and body components resist both field impacts and chemical exposure.

For distributors and dealers, the NTS423 rounds out a mist duster range with a flagship-power option: a portable backpack sprayer backed by standardized production, batch-to-batch consistency, and a structured parts catalog covering every critical system. Pest control backpack sprayer fleets, agricultural contractors, and municipal sanitation teams sourcing from garden machinery suppliers get one proven platform — with the coverage, economy, and engine options to match demanding professional schedules.
