Understanding Positive Displacement Blowers
Positive displacement blowers move a consistent volume of air or gas with every rotation, making them ideal for applications requiring steady, reliable flow. The Sutorbilt Legend Series uses bi‑lobe impellers and precision‑machined components to deliver dependable performance in continuous‑duty environments.
Bi‑Lobe vs. Tri‑Lobe Designs
Bi‑lobe blowers, like the Sutorbilt Legend Series, are known for their simplicity, durability, and proven performance across a wide range of OEM applications. Tri‑lobe designs are often selected for specific noise or pulsation characteristics. The Legend Series supports noise‑sensitive environments through its Quiet (Q‑Series) option.
Choosing Between Q‑Series and DSL Models
Q‑Series:
- Reduced noise levels (up to 5 dBA)
- High‑strength impeller case and specialized porting
DSL Series:
- Dual Splash Lubrication for cooler operation
- HighEnhanced timing and locking components
- HighExtended 30/24‑month warranty
