STIHL SR 450 Gas Backpack Mist Blower

The STIHL SR 450 is built for professionals who need the flexibility to switch between application methods without changing equipment. Designed to distribute both liquid and solid compounds, it converts from misting to dusting without special tools or additional equipment, making it easy to adapt as jobsite demands change.

Easy-to-use controls provide excellent control over product feed and air speed, helping operators make precise adjustments for a wide range of applications. Its low exhaust emission, fuel-efficient engine delivers a 20% greater spray range compared to previous models, helping you cover more area efficiently.

The multi-function control handle keeps essential controls within easy reach, allowing adjustments to be made comfortably while working. An adjustable support harness helps distribute weight across the shoulders and back, while the anti-vibration system helps reduce fatigue during extended periods of use.

Combined with simplified startup for quick restarts, the SR 450 is designed to help professionals stay productive from one task to the next.
