Key Differences Between Field King Max and Professional

While the Max and Professional share heavy duty designs and large tanks, the Professional model enhances performance and durability for intensive commercial use:

1. Tank Capacity

The Field King Professional model boasts a larger tank capacity of 5 gallons, which is a significant upgrade over the 4-gallon tank in the Max model.

This additional gallon allows for less frequent refilling, which is especially beneficial for large-scale spraying tasks. It reduces downtime and enhances productivity, particularly important in commercial settings where time efficiency is crucial.

2. Pump and Pressure

The Professional model is equipped with a superior diaphragm pump that can generate up to 100 PSI pressure, a noticeable improvement over the 80 PSI offered by the Max model.

This higher pressure output is advantageous for achieving a more extensive reach and ensuring that the spray penetrates dense foliage or other challenging environments.

This feature is especially useful for professionals dealing with varied terrains and vegetation types, requiring optimal spray power.

3. Nozzles

A key distinction between the two models is in the nozzle design. The Professional model utilizes an industrial fan tip nozzle, which offers fuller and more powerful spraying capabilities. In contrast, the Max model comes with an adjustable brass nozzle.

The industrial fan tip is ideal for covering larger areas more efficiently and is designed to withstand the rigors of commercial use, making it a preferred choice for users seeking enhanced performance and durability.

4. Weight

With enhanced features and build, the Professional model is understandably heavier, weighing in at 21 empty pounds compared to the Max’s 17 pounds.

This additional weight is a trade-off for the robustness and advanced capabilities of the Professional model. Users seeking a balance between portability and performance may need to consider this difference, particularly when dealing with extensive areas or long-duration tasks.

5. Warranty

Field King offers a more reassuring 2-year limited warranty on the Professional sprayer, indicative of its confidence in the model’s durability and reliability for intensive commercial use.

This is a step up from the 1-year warranty provided for the Max model. The extended warranty period provides users with additional peace of mind, especially those using the sprayer in demanding conditions.

6. Cost

Reflective of its advanced features, improved build quality, and enhanced performance, the Professional model comes with a higher price tag compared to the Max model.

While the initial investment is greater, the long-term benefits such as reduced downtime, better coverage, and extended warranty could justify the additional cost for users, particularly those in commercial sectors requiring reliable and high-performing equipment.
