Product description

generator exhaust silencer kit

The Perfect Companion For Your Generator Shed

This generator exhaust muffler kit, through a unique transmission path, alters the tone of noise, enabling noise cancellation and conversion to achieve noise reduction effects. The muffling and filtering cotton installed inside the pipe wall filters out solid matter in the exhaust gas emitted by the generator, allowing you to live free from noise disturbances.

Reverse Cross-patterned Design

The innovative fish-scale design of the inner chamber within the muffler tube, featuring alternating positive and negative hole directions along with segmented compartments within the tube, creates a distinct transmission path. This design enables sound entering through the positive and negative muffling holes to undergo multiple refractions, collisions, and cancellations along the inner walls of the tube, ultimately achieving an ideal noise reduction effect.

Silencing cotton

The interior interlayer of the muffler tube is filled with sound-absorbing cotton, which enables the generator to effectively absorb the noise generated during exhaust discharge and ventilation through the sound-absorbing filter cotton. This process not only dampens the noise but also effectively filters the exhaust gas emitted by the generator to a certain extent.

Widening waterproof exhaust port Employment of a widened exhaust port enables smoother gas expulsion during . Waterproof cover design, not afraid of stormy weather and rainwater backflow.

Powerful sealing performance

We come with a roll of sealing tape that is wrapped around the threaded portion of the fitting to make the fitting stronger and more airtight when rotating the installation!To avoid the problem of exhaust gas leakage caused by poor sealing performance at the joints during the exhaust process of traditional extended exhaust muffler, resulting in the exhaust gas not being completely discharged to the outside, we have designed threads at the joints of connecting pipes, adapters and other joints. By rotating and tightening the connection, the problem of exhaust gas leakage of traditional exhaust muffler is effectively solved.

Alloy Steel with Baked Paint Finish

The main muffler kit is crafted from hardened alloy steel and subjected to a baking paint coating process.Excellent rust and corrosion resistance enhances heat dissipation under varying environmental conditions.The wall mount bracket features a pressed-pattern fixing ring design, which minimizes noise caused by vibrations. Favourable heat dissipation from the muffler enclosure, reducing the spread of heat emitted by the muffler itself.

WIDE COMPATIBILITY Two different styles of exhaust adapters are included, ensuring compatibility with all brands and models of portable generators.

This includes compatibility with Firman models such as T07571, T07573, WH03242, & H07552, as well as Honda models like EU7000is and EU6500is, among others.

This feature ensures a stress free installation process for most generator mufflers with No. 68 and 88 spark suppressor filters, and spark suppressor holes with 1-1/2″ to 1-3/4″ spacing.

Installing Steps

Wall Mounting

Drill a hole with a diameter of approximately 5 inches on the wall (or wooden board), and install the mounting bracket of the exhaust muffler onto the wall (or wooden board) corresponding to the hole.

Exhaust Outlet Adapter

At the exhaust outlet of the generator, replace or install an adapter. Equipped with two styles of adapters, it offers wide compatibility with various generator models. Choose the suitable adapter and replace or properly install the exhaust adapter.

Connection at Both Ends

Connect the generator adapter to the exhaust muffler using a connecting hose by tightening it clockwise. First, tighten one end of the connecting hose (external thread) to the adapter interface installed on the generator, then tighten the other end (internal thread) to the threaded end of the exhaust muffler. Finally, thread the exhaust muffler through the wall bracket.
