Attenuators/Silencers (Flanged)

a muffler for your ventilation system. Just like a muffler quiets a car engine, a silencer is a metal tube lined with sound-absorbing material that bolts onto your ventilation fan to absorb roaring air noise.

What Does It Do?

• Traps Fan Noise: As loud air passes through the silencer, sound waves travel through holes in the inner metal lining and get trapped inside the soundproofing insulation.
• Keeps Air Moving: It quiets the system without blocking or slowing down the airflow, ensuring your ventilation still works at 100% capacity.

Key Advantages

• Peace and Quiet: It drastically reduces loud fan buzz and rushing air noises, creating a much more comfortable environment for staff and customers.
• Built to Last: Made from heavy-duty galvanized steel, it resists rust and corrosion, meaning it can be installed inside plant rooms or outdoors on roofs.
• Fast, Easy Installation: It features pre-drilled, threaded holes on both ends that match industry-standard fans perfectly. This makes bolting it into place quick and secure.
