A knapsack sprayer is an essential agricultural tool used for spraying pesticides, herbicides, fertilizers, and other liquid solutions across fields, gardens, and plantations. On the official Chandak Agro website, they offer a range of Knapsacks Power Sprayer models suitable for various spraying tasks in agriculture and horticulture.

Typically, the tank capacity of a knapsack sprayer ranges between 15 – 30 litres, with many common models designed around 20 litres to balance coverage and ease of use. This capacity allows users to cover a significant area before needing to refill, making it efficient for medium to large fields. The design ensures that the sprayer is comfortable to carry on the back, even when filled with liquid.

For more powerful applications, a knapsack power sprayer combines a motor-driven pump with this tank capacity, offering consistent pressure and improved spraying efficiency across crops.

Here are a few examples of popular knapsack sprayers available online:
Agricultural 20L Knapsack Power Sprayer – 20 L capacity, 2-stroke model
BALWAAN Krishi BKS‑35 Knapsack Power Sprayer – 25 L tank with 35 cc engine
Honda Type GX‑35 Knapsack Power Sprayer – 25 L 4-stroke unit

Choosing the right capacity depends on your field size and spraying needs , 20 L is ideal for most agricultural uses, while larger capacities help reduce refill frequency on bigger tasks.
