The 20L Electric Knapsack Sprayer from Agronest Equipment eliminates the physical effort of manual pumping, allowing you to focus entirely on spraying accuracy and coverage. Powered by a rechargeable 12V battery, the electric diaphragm pump maintains a steady 4–6 bar pressure throughout the entire tank without any manual intervention. The 20 litre capacity handles serious workloads across farms, estates, vineyards, and commercial grounds, while the battery provides 4–6 hours of continuous spraying, enough to empty the tank multiple times on a single charge. Multiple interchangeable nozzle attachments give you the flexibility to switch between wide-area herbicide coverage and precision spot treatments within seconds. Padded backpack straps distribute the weight comfortably, and the convenient on/off switch mounted on the spray lance handle gives you instant control without reaching behind you. For professional farmers, landscapers, grounds maintenance teams, and pest control operators who spray large areas daily, this electric knapsack sprayer delivers consistent, fatigue-free performance that manual models simply cannot match.
