How much pressure can a plastic protective vent withstand

• Material Type: High-density polyethylene (HDPE) and polycarbonate vents can resist 15-25 psi, while lightweight PVC vents typically handle only 5-10 psi.
• Structural Design: Reinforced frames, ribbed patterns, or multi-layer constructions enhance pressure resistance. Cross-bracing distributes pressure evenly.
• Environmental Conditions: Extreme temperatures affect performance - cold makes plastics brittle, while heat can cause deformation.
• Installation Quality: Properly installed vents without gaps perform better under pressure.

Always refer to manufacturer's specifications and conduct load-testing for precise pressure tolerance in specific applications.
