Consider the pressure level ( psi ) , cooler capacity , the type of liquified manner of speaking system , and the type of pump that pressurizes the backpack spray .
Pressure
Pounds per square inch ( psi ) is the whole of measure distinguish the amount of pressure a backpackherbicide sprayercan propel through its nozzle . The average for a backpack sprayer is around 70 psi , but smaller role model can use as little as 40 pounds per square inch , and a commercial backpack nebulizer may apply as much as 150 pounds per square inch .

Manual vs. Motorized
Backpack sprayers use an internal pump to draw liquid out of the bedchamber , through a hose , and out through a wand and nozzle . This pump can be operated manually , or an galvanizing rucksack sprayer will often use a motorize system — the pricier option .

Motorized backpack sprayers are powered either by battery or gun , with a battery backpack sprayer pop the question more versatility and a simple apparatus . A motorized sprayer automatically pump the liquid from the rucksack chamber to the sceptre , requiring no physical work by the substance abuser . Intended for prominent project and long workday , a motorise spray ( which can run between about $ 100 and $ 500 ) is a better choice for the busy professional who ’ll rely on it day by day .
