Grower Tip
- Use matching 150mm fan and duct connections to avoid restrictive reducers around the silencer.
- Place it anywhere in the intake or exhaust chain where the 150mm connections remain accessible.
- Seal and clamp adjoining ductwork carefully so air leaks do not add unnecessary system noise.
Features
Dual 150mm | 6-inch flanges integrate with matching inline fans and ventilation ducting.
Wave-pattern neoprene foam dampens airflow sound while leaving the central air path open.
The silencer is rated to reduce fan and airflow noise by up to 50% in a suitable installation.
Reversible metal flanges support installation in intake or exhaust ventilation layouts.
A galvanised steel body surrounds the acoustic lining for a rigid, corrosion-resistant enclosure.
-
1
Plan the position
Choose an accessible location in the 150mm intake or exhaust chain with room for both flange connections.
-
2
Match the connections
Confirm the fan, ducting and silencer all use nominal 150mm | 6-inch openings.
-
3
Join both flanges
Connect the adjoining fan or ducting to each flange and secure every joint with suitable clamps.
-
4
Check the system
Run the ventilation system and inspect the connections for movement, air leakage and unwanted vibration.
What fan and duct size fits this silencer?
This model uses nominal 150mm | 6-inch openings at both ends. Pair it with an inline fan and ducting of the same nominal size for a direct connection. Reducers may change airflow and installation requirements, so size-matched components are preferred.
Where can the silencer be installed?
It can sit at different points in a 150mm ventilation chain, including intake and exhaust layouts or between an inline fan and ducting. Choose a position with enough clearance to secure both flanges and inspect the connections after installation.
Will it restrict ventilation airflow?
The neoprene acoustic foam follows the inside wall in a wave pattern while the centre remains open for airflow. Every added component still creates some system resistance, so use matching 150mm connections and keep the surrounding duct run smooth and correctly sized.
How much noise can it reduce?
The product is rated for up to 50% reduction of fan and airflow noise in a suitable installation. Actual results vary with fan speed, duct layout, vibration transfer, connection quality and the surrounding room. It reduces noise rather than making ventilation silent.
Description
A ventilation ducting tool designed to dampen or reduce noise coming from airflow in grow tent or server closet ventilation systems.
It utilizes high-grade neoprene foam crafted in a wave crest pattern that diminishes sound wave movement, reducing noise pollution by up to 50%. The egg crate foam muffles sound vibration while allowing maximum airflow passthrough for both intake and exhaust configurations.
Both aluminum flange openings also assist in absorbing sound waves from vibrations, seamlessly fitting over your inline duct fan’s flange. Each silencer is built with a solid galvanized steel body that is corrosion-resistant and can withstand extreme temperature changes.
APPLICATIONS
The duct silencer is often paired with inline extractor fans in grow tents and hydroponic grow room applications. It can be installed anywhere in the ventilation system chain like in between the fan and ducting. The silencer can also be used in many home HVAC applications including AV equipment room cooling, closet cooling, and bathroom ventilation. This creates a comforting home environment that is quieter and more relaxing, or a workplace that is less distracting.
