30L Rolling Sprayer with Self-Cleaning and Variable Speed

The 30L Rolling Sprayer with Self-Cleaning and Variable Speed from Crosstec is designed for growers, landscapers, pest control contractors, and agricultural distributors seeking a reliable and low-maintenance spraying solution. Combining a large-capacity tank, patented self-cleaning technology, variable speed control, and a durable diaphragm pump, this battery-powered rolling sprayer delivers consistent performance for orchards, farms, nurseries, vineyards, and public sanitation projects.

Compared with conventional backpack sprayers, this lithium-powered rolling sprayer significantly reduces operator fatigue while increasing spraying coverage and productivity. The rolling design allows users to work longer with less physical effort, making it an ideal choice for commercial and professional applications.

Key Features & Benefits

Large 30L Capacity for Higher Productivity

The large 30-liter tank minimizes refill interruptions and improves work efficiency during large-area spraying operations.

• 30L (8 Gallon) capacity for extended coverage
• Suitable for orchards, vineyards, nurseries, and farmland
• Less downtime and higher spraying efficiency
• Ideal for commercial agricultural spraying projects

Patented Self-Cleaning System Reduces Maintenance

One of the biggest challenges in agricultural spraying is chemical residue accumulation inside the pump and hose system. The patented self-cleaning technology developed by Crosstec automatically flushes residual chemicals after operation.

• Prevents crystallization and sediment buildup
• Reduces pump blockage risks
• Extends diaphragm pump lifespan
• Minimizes maintenance requirements
• Improves long-term equipment reliability

For distributors and professional users, this feature helps lower maintenance costs and improves equipment uptime throughout the spraying season.

Variable Speed Control for Precise Application

Different spraying tasks require different output levels. The variable speed system allows operators to adjust flow rate according to crop type, chemical concentration, and spraying distance requirements.

• Fine mist for seedlings and greenhouse crops
• Medium flow for vegetable farms and nurseries
• High-pressure spraying for orchards and vineyards
• More accurate chemical application
• Reduced chemical waste

The 30L Rolling Sprayer with Self-Cleaning and Variable Speed provides greater spraying flexibility compared with fixed-pressure sprayers.

Industrial-Grade Diaphragm Pump

Built around a corrosion-resistant diaphragm pump, the system is designed to handle a wide range of agricultural and sanitation chemicals.

• Pump life up to 1000 hours
• Corrosion-resistant internal components
• Suitable for pesticides, herbicides, fertilizers, and disinfectants
• Stable pressure output
• Low noise operation

Unlike piston pumps, diaphragm pumps provide smoother flow and better chemical compatibility, making them a preferred choice for professional spraying equipment.

20V Lithium Battery Platform

The sprayer is powered by a 20V lithium battery system with intelligent battery management protection.

• Over-charge protection
• Over-discharge protection
• Short-circuit protection
• Long runtime for field operations
• Quick charging capability

The battery-powered design eliminates fuel costs, engine maintenance, and exhaust emissions associated with gasoline sprayers.

High-Pressure Long-Distance Spraying

The included high-pressure spray gun and interchangeable nozzle system provide excellent coverage for both close-range and long-distance applications.

• Spraying distance over 10 meters
• Vertical reach up to 5–6 meters
• Multiple spray patterns available
• Suitable for tall fruit trees and vineyard rows

Heavy-Duty Rolling Structure

The rolling frame design improves mobility across various terrains while reducing operator fatigue.

• Easy transportation across fields and gardens
• Stable support during spraying
• Comfortable ergonomic handle
• Suitable for uneven agricultural terrain
