Description
For the commercial operator, RedMax is easily the industry leader in terms of the selection and performance of power blowers. The EBZ5150RH backpack blower features the Strato-Charged 2-stroke engine with ultra-low emissions and high power. With a 50.2 cc displacement and 2.3 horsepower, the EBZ5150RH produces a maximum air speed of 215 MPH with tube air flow approaching 435 CFM. The Max Cooled back pad uses air from the fan housing to cool operators and keep them comfortable during hot days. Super wide straps and contoured back pad are oversized for greater comfort. Comes standard with a tube mounted throttle.
Zoom on the RedMax EBZ5150RH
With its gas backpack design, the RedMax EBZ5150RH is appropriate for homeowners with properties with wide lawns, large gardens, or estate-sized grounds over half an acre.
It is rated for a max air volume of 434 cubic feet per minute (CFM) and a max air speed of 215 MPH. Practically, this means the blower offers modest airflow but strong speed, making it effective for focused clearing on small yard areas, patios, or garden paths.
The EBZ5150RH features a 50.2-cc 2-stroke Strato-Charged® engine and runs on a 50:1 fuel-to-oil mixture. Its tank holds 70.9 fluid ounces, placing it in the average range among backpack blowers.
In order to afford more control to the user, this unit has a variable speed control. No matter the size of the job, the user can adjust the airflow of the RedMax EBZ5150RH to match.
With a dry weight of 20.7 lbs, the backpack format helps reduce arm fatigue while maintaining steady airflow control. Its throttle is located on the tube, which allows to keep the left hand free.

The RedMax EBZ5150RH's performance versus other blowers
The following charts are provided to give you an idea how the key specs of the RedMax EBZ5150RH compare with similar leaf blowers.
- In its category of gas-powered backpack blowers between 45.1 and 60cc, the RedMax EBZ5150RH delivers an average weight build at 20.7 lbs. Should weight be a deciding factor, the PRORUN PBB2417 is worth a look at just 19.2 lbs.
- The RedMax EBZ5150RH expels air at speeds up to 215 MPH, showcasing typical air speed performance for gas-powered backpack blowers between 45.1 and 60cc. If you wish to benefit from air expelled at the fastest possible speed, the Husqvarna 150BT and its 270 MPH could be an option to consider.
- As this unit is rated at 434 CFM (cubic feet per minute), it expells less air than most gas-powered backpack blowers with a comparable engine size. For the highest air volume, you may want to have a look at the Echo PB-5810T, which boasts with 700 CFM.
Strato-Charged Engine Technology

RedMax's Strato-Charged 2-stroke engines are efficiently designed with just 3 moving parts. This allows them to be up to 20% more fuel-efficient than standard 2-stroke engines, to be 20 to 25% lighter than 4-stroke engines of the same size, and to produce low emissions that meet regulations without the need for a heated, heavy catalytic converter. Offering much less operator fatigue, these engines have a high power to weight ratio and can therefore be classified as high-performance.
The bottom line
- Strato-Charged® Engine
- Decent tank (70.9 fl. oz.)
- Decent weight (20.7 lbs)
- Decent MPH (215 MPH)

About RedMax
RedMax is an established power equipment brand in North America, known for its trimmers, chainsaws and, of course, leaf blowers. Interestingly, the company traces its roots back to Japan, where it was founded in 1910 as the Tokyo Gas Kogyo Company. TGCK went through numerous name changes and settled with the names Komatsu Zenoah (globally) and RedMax/Zenoah (North America), under which they sell their products to this day. The company was acquired by Husqvarna in 2007. RedMax has a somewhat extensive portfolio of more than 10 leaf blowers, both backpack and handheld, and has recently launched a battery powered product line. RedMax products are produced in various plants over the globe, which are not limited to Japan.
