Backpack motorized sprayers are indispensable for plant protection.

Backpack electric sprayer is one kind of plant protection machinery, which is widely used in agricultural plant protection work.

In the 1990s, the use of backpack electric sprayers gradually increased, but because of the large size is not conducive to a long period of operation. 2005, the WH-5 backpack ultra-low volume electric sprayer was born to avoid the disadvantages of the traditional backpack electric sprayer. Its features are:

1, the appearance of more innovative design: the overall design is more in line with people's traditional habits - backpack, the appearance of novel and generous structure is reasonable, outstanding personality, easy to operate.

2, liquid barrel capacity: liquid barrel capacity of 10 liters (10 kg), can spray 3-5 acres (666.7 square meters / mu).

3, large spray volume: by adjusting the rotational speed of the centrifuge and increasing the speed of liquid flow, the sprayed fog is more and denser. So the spray is more thoughtful and covers a wider area.

4, dual-use battery more convenient: in the use of four batteries on the basis of the first, but also equipped with a battery as a power source, this battery maintenance-free, large capacity, power enough to use more labor-saving. 

5, the nozzle is more flexible: flexible nozzle makes the user more at will, where you want to spray where you spray.
