Phat Compact Inline Muffler / Silencer - 100MM x 280MM

The Phat Inline Silencer 100 x 280MM is a compact ventilation muffler designed to reduce noise produced by inline fans and air moving through ductwork. With a 100MM (4 inch) connection, it is ideal for compatible hydroponic grow tents, grow rooms, indoor gardens and other ducted ventilation systems.

Featuring an 85% Noise Reduction Coefficient (NRC), the Phat Silencer uses specialised glass pack acoustic material to absorb and reduce ventilation noise. Unlike conventional foam materials that can deteriorate over time, the Phat glass pack is designed to provide durable sound attenuation.

The lightweight aluminium construction makes the silencer easy to handle, install and suspend while providing resistance to rust. A 45-degree internal taper before the flanges is incorporated into the design to further assist with noise reduction.

Despite its sound-dampening construction, the Phat Inline Silencer is designed for maximum free-flow air movement, helping minimise unnecessary airflow restriction within the ventilation system.

The muffler is non-directional, so it can be installed with airflow travelling through it in either direction. When using only one silencer, installation on the intake side of the fan or blower is recommended for maximum sound attenuation. For additional noise reduction, one muffler can be installed on the fan intake and another on the outlet.

For standard installations, the 100MM Phat Muffler should be paired with 100MM ducting and a compatible 100MM inline fan. The silencer can be secured using suitable self-tapping sheet metal screws or duct tape, or suspended using chain or rope around the housing.

Keep the Phat Muffler dry during operation. If it becomes wet, allow it to dry thoroughly before returning it to normal use.
