The Blauberg Gravity Ventilation Grille is designed for homeowners and contractors seeking a durable, aesthetic exterior termination point for 100mm ventilation systems in bathrooms, kitchens, and utility rooms. Its primary benefit is the combination of a sleek, modern slate grey finish with a functional gravity shutter that effectively minimizes backdrafts and prevents debris intrusion, though users should note it is strictly intended for 100mm ducting and requires precise surface mounting.

While it fits 100mm ducting, gravity grilles are primarily designed for bathroom and kitchen ventilation; check your dryer's manual for specific venting requirements.
It is designed as a push-fit unit, but we recommend using a suitable exterior-grade silicone sealant to secure the unit to the wall.
It is made of high-quality PVC; if you choose to paint it, ensure you use a plastic-compatible primer and paint suitable for exterior use.
The exterior face of the grille measures 155mm by 155mm.
Yes, the fixed-louvre and gravity shutter design provides a significant barrier against birds, rodents, and large insects.
Clean any dust or debris from the hinge points of the louvres with a soft brush and ensure the unit is installed perfectly level.
Check that the shutter hinges are not damaged and ensure the grille is securely fastened to the wall surface.
Installation is straightforward due to the 155x155mm push-fit design. Simply ensure your existing 100mm ducting is flush with the exterior wall surface, apply a suitable sealant or adhesive around the backplate, and press the unit into place. For maintenance, it is recommended to inspect the grille annually; use a soft brush or a damp cloth to remove any accumulated dust or spiderwebs from the louvres to ensure they continue to open and close freely. Avoid using harsh chemical cleaners, as they may affect the finish of the PVC.
