Packing list

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. Choose MADONGLI for a green and healthy lifestyle.

The main muffler kit is crafted from hardened alloy steel and subjected to a baking paint coating process.Rust and corrosion resistance, enhanced ability to dissipate heat under varying environmental conditions.

The wall mount features a snap-fit retention ring designed to maximize clamping force on the exhaust outlet and minimize noise from vibration. Additionally, it facilitates heat dissipation from the muffler housing, reducing the transmission of heat emitted by the muffler itself.

Employment of a widened exhaust port enables smoother gas expulsion during .

The exhaust extension pipe and fastening U-clamps of our muffler are made of 304 stainless steel, providing excellent corrosion resistance and rust prevention. They are suitable for use in various harsh environments and have a long service life.

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.

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.

Begin by drilling an approximately 5-inch hole in the wall or wooden board. Next, attach the mounting bracket for the exhaust muffler over this hole. Finally, guide the exhaust muffler through the bracket to complete the installation.

To begin at the generator's exhaust outlet, replace or install an adapter. This kit provides four adapter styles for broad compatibility with various generator models. Simply choose the one that matches your generator for a proper and secure installation.

After setting the distance between the generator and muffler, join them with the matching 304 stainless steel corrugated pipe. The connectors should be inserted into the pipe, ensuring a segment of the corrugated section remains visible at both ends.

To reduce exhaust backflow and enhance the seal, we provide a fiberglass aluminum foil tape. Please wrap this tape around the joint-pipe connection and then secure it firmly with the 304 stainless steel U-clamp.
