Once again we get into an interesting area. This blower pushes about 480 CFM of air, which quite frankly is a lot. I prefer turbo mode because it moves so much air so fast that small rocks and debris are able to be blown away and I get the same results as I would a gas blower.
Now pressure is an interesting thing. These turbine blowers don't have as much pressure. You can stop the airflow easier, but they have better air output. I'm going to blow this answer up, I feel it coming. I wouldn't measure the blower by PSI, but rather amount of air. Here are the only specifications that are available.3-Speed Design
- Speed 1 - High Efficiency: 250 CFM
- Speed 2 - High Power: 385 CFM
- Speed 3 - Turbo Boost: 480 CFM
So as the motor speed increases, the pressure in the tube also increases and the CFM increases.
