The use of backpack-type ultra-low power sprayer

WH-5 Knapsack Ultra Low-Voltage Electric Sprayer was finally designed and trial-tested by the scientific research personnel of Beijing Ruzhi Agriculture and Forestry Technology Co., Ltd.!

The WH?5 backpack-type ultra-low-volume electric atomizer has maintained the following advantages on the basis of maintaining the good workmanship, labor-saving, water-saving, medicine-saving, and high-efficiency of the Haoyao brand products:

1. The appearance design is newer: The overall design is more in line with people's traditional habits. The backpack has a novel appearance, reasonable structure, outstanding personality, and simple operation.

2. The capacity of the liquid barrel is large: the liquid barrel capacity is 10 liters (10 kilograms), which can spray 3-5 acres (666.7 square meters/mu).

3, the amount of spray: by adjusting the speed of the centrifuge and increase the speed of liquid flow, so that more and more dense spray. Therefore, the spray is more thoughtful and covers a wider area.

4, dual-use battery is more convenient: In the use of four quarters on the basis of the battery, but also equipped with a battery as a power supply, this type of battery maintenance-free, large capacity, power enough to use more effort.

5, nozzle more flexible: flexible nozzle allows users to more freely, where to spray where to spray.

Oxygen Cylinder Filling System

With PSA principles, ETR Oxygen Cylinder Filling system can produce 93%±3% purity oxygen gas from compressed air directly.  ETR oxygen cylinder filling system is consisted of Atlas screw air compressor, refrigerated air dryer, compressed air filter, air buffer tank, ETR Oxygen Plant, oxygen buffer tank, oxygen booster, cylinder filling station and HMI control cabinet. 


Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure. With an oxygen booster, the oxygen pressure can be to 150bar and fill in cylinders.
