🔥 Why Standard 90° Vent Caps Cause Problems
Most standard 90° vent caps use a sharp angle:
Creates airflow turbulence
Traps condensation
Increases risk of clogging
👉 In drainage systems, sharp bends can increase blockage risk due to flow resistance
👉 That’s why professionals prefer long sweep designs
✅ Long Sweep 90° — Designed for Real Flow
This is NOT a basic 90° vent cap.
👉 It features a long sweep 90° curve, which:
Reduces airflow resistance
Improves system efficiency
Helps prevent condensation buildup
👉 Long sweep fittings are widely used to minimize clogging and improve flow performance
🌧️ Built for Rain & Outdoor Protection
Downward-facing outlet blocks rain entry
Helps drain condensation naturally
Reduces freeze risk in winter
👉 90° vent terminations are commonly used to prevent water intrusion while maintaining airflow
💨 Maintains Proper Airflow & Drainage
Unlike restrictive vent covers:
Smooth internal curve
Open flow path
No pressure buildup
