Description

Overview of the Senix BLB4QL-M

  • Power: The BLB4QL-M gas-powered blower, manufactured by Senix, is rated for a max air volume of 600 cubic feet per minute (CFM) and a max air speed of 200 MPH.
  • Handling: By design, this model isn’t the smallest leaf blower on the market. It’s meant to be carried as a backpack so that the bulk of the unit is out of the way and the user’s hands are free to manipulate the nozzle. Its throttle is located on the tube, which allows you to keep your left hand free. Compared to its counterparts, the Senix BLB4QL-M stands out as a lighter option within the gas-powered backpack category, weighing only 19.4 lbs.
  • Engine: The blower is fitted with a 49cc engine. As this is a 4-stroke engine, the blower does not require a mix of gas and oil in order to run.
  • Speed Settings: Users can fine-tune airflow with the variable speed settings of the BLB4QL-M, complemented by intuitive cruise control for effortless use.
  • Fuel Tank: Its tank can hold 42 fluid ounces, so it falls squarely in the average in terms of fuel capacity for backpack blowers.
