Overview

Highlights

High Productivity.

Mist dusters (NTS420, SR420, NTS423) use a 41.5–72.3cc engine and fan to throw liquid or powder over a long horizontal reach (the NTS423 lists up to 15 m horizontal reach), which reaches the top of fruit trees. Power sprayers such as the 26cc NTS768 with a 25 L tank use a piston pump for fine, even droplets on vegetables and vineyards. Manual 16–20 L sprayers with brass pumps need no fuel and suit smallholders.

Applications

Orchard and vineyard spraying
Field crops and vegetables
Greenhouse and warehouse fogging
Mosquito and public-health pest control
Powder dusting and seed spreading

Ordering and OEM

Thermal foggers turn chemicals into a dense fog for greenhouses, warehouses and mosquito control.

Questions

What engine does the SR420 56.5cc 2-Stroke Knapsack Mist Duster use?

It uses a 56.5cc 2-stroke gasoline engine rated at 2.6kW/3.5hp/6000rpm. Full engine data is in the specification table on this page.

Can the SR420 56.5cc 2-Stroke Knapsack Mist Duster be supplied with my brand?

Yes. Housing colour, logo decals, manuals and cartons can carry your brand. We send artwork proofs before production.

What warranty and certification does it have?

Warranty is 6 months for core parts. Ask for certificate copies with your quotation.

How is it packed for export?

Each unit is packed in an export carton with inner protection. Mixed-model containers are available.

What is the difference between a mist duster and a power sprayer?

A mist duster uses a high-speed air stream to carry droplets or powder over a long distance and into dense canopies. A power sprayer uses a pump to create pressure and is better for precise, low-volume spraying close to the plant.
