AC Infinity Inline Duct Fan Silencer – 6-inch Noise Reduction Muffler for Grow Tents

Enhance your airflow with a quieter, more efficient solution

AC Infinity presents the Inline Duct Fan Silencer, a purpose-built muffler designed to complement inline fans in grow tents, bathrooms, and HVAC duct runs. By softening the whirr and dampening vibrations, it helps create a calmer environment around your ventilation setup without sacrificing airflow or performance.

The heart of the unit combines two aluminum flanges that help absorb sound waves from both vibration and moving air. Paired with a neoprene foam pad laid out in an egg crate pattern, it tackles a broad spectrum of noise-producing frequencies, delivering a noticeable reduction in environmental din during operation.

Design highlights and what it brings to your space

• Designed for use with inline fans in grow tents, bathrooms, and other HVAC applications, supporting versatile setups.
• Dual aluminum flanges help absorb vibrations from fan movement and airflow, smoothing perceived noise.
• Neoprene foam in an egg crate pattern lowers noise by up to 50% under typical conditions, creating a more comfortable space.
• Galvanized steel body offers corrosion resistance and endurance in varied temperatures for long-lasting use.
• 6-inch duct opening, 12.87-inch length, and a 3.9-pound weight support straightforward integration into common duct runs.

Practical, real-world uses

• In hydroponics tents, it helps keep the sound footprint from overpowering nearby equipment while preserving exhaust consistency.
• In bathrooms or kitchens, it modulates vent noise in compact, high-traffic installations without sacrificing ventilation.
• In residential HVAC ducts, it serves as a compact muffler option for mid-size duct runs with steady airflow.

How to get the most out of your silencer

• Place the muffler inline with the fan and align it with the straightest segment of ducting for best performance.
• Avoid sharp bends near the unit to minimize turbulence and maintain attenuation efficiency.
• Keep the unit clean and periodically inspect the foam padding for wear or compression.
• Match the 6-inch opening to compatible ducts and fittings to preserve a smooth airflow path.
