Types of Products

  • Manual: You will flick the hand lever several times to create pressure in the tank. Flesser Sprayer or Rainmaker 4 Gallons are such sprayers.

  • Electricity: These products run on batteries. The average usage time of the device is 1.75 hours. Some models such as WOEKBON 4 or VIVOSUN 4 have a usage time of up to 8 hours from a full charge.

Buying Guides

You can be highly disappointed when you buy the wrong backpack sprayer that doesn't fit your needs. To avoid this, you should consider the following factors when choosing to buy a product:

  • Pump type: piston or diaphragm construction? Piston pumps can produce high pressure but are pretty limited in handling concentrated solutions or absorbent powder products.

Meanwhile, you can still be satisfied with diaphragm construction models with only 40 to 60 psi pressure but are suitable for most liquids.

  • Product comfort: To assess comfort, you can check through the strap, especially the waistband. A good waist strap will help distribute the load evenly. From there, you can better control the sprayer and limit pain.

  • Safety: the perfect sprayer needs to have a tight lid, minimizing the leakage of chemicals. To be on the safe side, you should consider models with trigger protection, such as the Field King Max 190348 or the Field King 190515. It will be an investment you won't regret.
