Flap / Gravity Gates
Simple, Reliable Backflow Prevention
In dust handling and low-pressure discharge systems, simplicity often defines reliability. Flap and Gravity Gates are engineered to provide passive or controlled backflow prevention while allowing smooth material discharge.
Oswar Rotocorp Flap / Gravity Gates are designed for dust collectors, silos, and low-pressure conveying systems where dependable one-way flow is critical.
What Flap / Gravity Gates Do
Flap / Gravity Gates perform essential roles in bulk material systems:
- Prevent reverse air flow
- Allow gravity-based material discharge
- Isolate low-pressure zones
- Protect dust collection system performance
- Minimize air ingress into process lines
These gates are particularly effective in systems where maintaining airflow balance is essential for filtration efficiency.
