The Westinghouse 4LB4AH4BC's performance versus other blowers

The following charts are provided to give you an idea how the key specs of the Westinghouse 4LB4AH4BC compare with similar leaf blowers.

  • Upon exiting the nozzle, the air can reach speeds of up to 90 MPH, which is on the lower end for battery-operated handheld blowers. For the fastest air speed in this category, you may want to consider the Makita XBU01PT, which can expell air at a velocity that can reach 208 MPH.
  • It has a maximum air volume output of 400 CFM (cubic feet per minute). With this output rating, the 4LB4AH4BC is well within average in relation to similar cordless handheld blowers. If air volume is important to you, the Ryobi RY404100, with 730 CFM, could be in your good books.
  • Thanks to its autonomy of up to 60 mins, the 4LB4AH4BC benefits from a higher run time than many cordless handheld units. If autonomy is an important factor for you, the EGO POWER+ LBX6000 can run for up to 96 minutes and could be worth considering.

About Westinghouse

The used-to-be Westinghouse Electric Corporation, yet nowadays, simply known as the Westinghouse label, is a brand of the notorious American CBS. However, Westinghouse itself, or rather the original Westinghouse Electric Corporation, traces its roots back to 1886. The electrical company has dealt in many businesses, including power tools, which were manufactured and sold under their Westinghouse Outdoor Power Equipment branch. These products have gained such a strong reputation, that they have retained the Westinghouse name even after the merger. While Westinghouse is most well known for its generators, their portfolio also contains a range of electric lawn equipment, including leaf blowers, powered by exchangeable batteries.
