Gravity Louvre Shutter 549x549mm Frame
£77.12
Gravity Louvre Shutter – Vertical Wall Mounted (PVC)
- 549 × 549 mm – suitable for ducts up to Ø510 mm
This gravity louvre shutter is a robust, weather-resistant external shutter designed for vertical wall mounting on ventilation supply or extract systems.
Its square-profile design with aerodynamically profiled vanes creates a strong upward opening force, allowing the shutter to open fully at very low air velocities. This reduces air resistance and pressure loss, making it ideal for low-pressure ventilation applications.
Manufactured from high-quality weather-resistant PVC, the shutter is built to withstand demanding external conditions. The rigid construction ensures the vanes remain stable, secure, and resistant to deformation over time.
