•The data shown above are those in the case of one straight pipe and round pipe.

•Specifications are subject to change without notice.

Note 1: Noise emissions in the environment measured as sound power (LWA) in conformity with EC directive 2000/14/EC. Reported sound power level for the machine has been measured with the original attachment that gives the highest level. The difference between guaranteed and measured sound power is that the guaranteed sound power also includes dispersion in the measurement result and the variations between different machines of the same model according to Directive 2000/14/EC.

Note 2: The equivalent sound pressure level value is calculated with a work cycle of a duration of 1/7 for idling and 6/7 for racing. Reported data for equivalent sound pressure level for the machine has a typical statistical dispersion (standard deviation) of 1 dB(A).

Note 3: The equivalent vibration total value is calculated with a work cycle of a duration of 1/7 for idling and 6/7 for racing. Reported data for equivalent vibration level has a typical statistical dispersion (standard deviation) of 1 m/s2.

BB2250 specifications

The Jonsered BB2250 is a powerful and versatile backpack blower designed to meet the demanding needs of both professional landscapers and passionate homeowners. With a focus on efficient performance and user comfort, the BB2250 offers several key features that set it apart from its competitors in the market.

One of the standout characteristics of the BB2250 is its robust engine. It is powered by a 50.2 cc, 2-stroke engine that delivers an impressive airspeed of up to 800 CFM (Cubic Feet per Minute) at a maximum speed of 200 mph. This high performance allows users to tackle even the most stubborn leaves, debris, and grass clippings with ease, making quick work of yard maintenance tasks. The engine is designed for fuel efficiency, enabling extended runtime without sacrificing power.

Ergonomics play a significant role in the design of the Jonsered BB2250. The tool is equipped with a padded harness and adjustable shoulder straps, ensuring that the blower can be worn comfortably for extended periods. This is particularly beneficial for professionals who may spend hours operating the blower. The adjustable tube length also allows users to customize the tool to their height, further enhancing comfort and control.

The BB2250 features advanced anti-vibration technology, which significantly reduces the amount of vibration transmitted to the operator's hands and arms. This not only helps minimize fatigue during long working sessions but also enhances overall safety while using the blower. The easy-to-use throttle control and cruise control functions provide greater precision and allow for more controlled operation, contributing to a better user experience.

Maintenance is made simpler with Jonsered’s innovative air filtration system. The system ensures excellent airflow while keeping dirt and debris out of the engine, leading to prolonged engine life and reduced maintenance needs. Additionally, the blower's lightweight design aids in portability, making it a practical choice for users who need to move between various job sites or around their property.

Overall, the Jonsered BB2250 stands out as a reliable and efficient backpack blower. Its powerful engine, ergonomic design, low vibration, and easy maintenance make it an excellent choice for anyone looking to keep their outdoor spaces tidy and well-maintained. Whether for professional landscaping services or personal use, the BB2250 is built to deliver exceptional performance while keeping user comfort in mind.
