Description

38% More Air Movement Than the Competition. Little Wonder Optimax blowers are the best-designed blowers in the world… known for unmatched leaf-blowing efficiency. (source: Little Wonder)

Overview of the Little Wonder LB390H

  • Power: The LB390H, built by Little Wonder, is a gas-powered leaf blower capable of expelling a maximum air volume of 2530 cubic feet per minute (CFM). Its air speed is rated at 160 MPH.
  • Handling: For bigger jobs covering a large area or for those who simply want to keep their leaf blower on the ground, walk-behind blowers such as the Little Wonder LB390H are an ideal choice. They are typically much more powerful than handheld or backpack blowers.
  • Engine: This blower's Honda engine has a displacement specification of 389 cc. As this is a 4-stroke engine, the blower does not require a mix of gas and oil in order to run.
  • Speed Settings: Sometimes you just need a little more power, while other times you may want a little more precision when moving leaves and debris. That’s why the LB390H features variable speed settings for added control.
  • Fuel Tank: With a capacity of 204.8 fl. oz., this Little Wonder blower is average compared to other gas walk-behind blowers.

The Little Wonder LB390H's performance versus other blowers

The following charts are provided to give you an idea how the key specs of the Little Wonder LB390H compare with similar leaf blowers.

  • Upon exiting the nozzle, the air can reach speeds of up to 160 MPH, which is on the lower end for gas-powered walk-behind blowers. For the fastest air speed in this category, you may want to consider the Cub Cadet CB2900, which can expell air at a velocity that can reach 200 MPH.
  • Regarding its air volume, the Little Wonder LB390H boasts an impressive airflow that can reach 2530 CFM (Cubic Foot per Minute). This places it amongst the most powerful gas-powered walk-behind blowers. If air volume is important to you, the Billy Goat F1802V, with 2900 CFM, could be in your good books.

OPTIMAX™ Technology

The Little Wonder LB390H benefits from a reversed angle fan blade that is a lot different from other blowers: it improves the fan efficiency and, when combined with a scrolled housing, allows the blower to move more air than many other wheeled blowers. The air deflector in an Optimax™ walk-behind leaf blower splits the airstream to direct the fastest moving air where it’s needed the most. Moreover, its low lying discharge chute gets the airflow closer to the surface. For surface treating, this allows it to clear small particles. For surface drying, this allows it to move standing water.
