Phat Compact Inline Muffler / Silencer - 150MM x 330MM

The Phat Inline Silencer 150 x 330MM is a compact acoustic muffler designed to reduce noise generated by inline fans, blowers and air travelling through ventilation ducting. Featuring a 150MM (6 inch) connection, it is ideal for compatible hydroponic grow rooms, grow tents, indoor gardens and ducted extraction 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-based materials that can deteriorate or disintegrate over time, the Phat glass pack provides a durable solution for ongoing fan and airflow noise management.

The lightweight aluminium construction makes the silencer easy to handle, install and suspend while providing resistance to rust. A specially designed 45-degree internal taper before the flanges further assists with sound attenuation while supporting smooth airflow through the unit.

The Phat Inline Silencer is engineered for maximum free-flow air movement, helping reduce fan and duct noise without unnecessarily restricting airflow through a correctly configured ventilation system.

Its non-directional design allows the muffler to be installed with airflow travelling through it in either direction. If 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 intake and another on the outlet.

For standard installations, the 150MM Phat Muffler should be matched with 150MM ducting and a compatible 150MM inline fan. It can be secured using suitable self-tapping sheet metal screws or duct tape, or suspended using chain or rope wrapped around the housing.

The Phat Muffler should be kept dry during use. If it becomes wet, dry it thoroughly before returning it to normal operation.
