M Series Chamber Type Silencers

Maxim's M Series Chamber type silencers provide the best noise control across the entire audible range. The basic design incorporates non-resonant side tube arrangements to permit passage of the exhaust gases from one chamber to another. This creates a reversal of flow and develops a predictable amount of back pressure. Another important feature of chamber type silencers is the availability of side inlet exhaust connections. Units of this type, except for spark arrestor designs, can also be supplied with side outlet exhaust connections. These side connections, while having little effect on the pressure drop, will in many instances greatly facilitate installation of the silencer by eliminating the need for elbows in the exhaust piping.
M22 Residential grade chamber type silencer, expected attenuation is 20 to 25 dBA.Residential and light industrial areas where background noise is relatively high and constant and the need for higher degrees of silencing is minimal.
M32 Critical grade chamber type silencer, expecteded attenuation is 25 to 32 dBA. Residential areas where background noise is present but not objectionable. In these areas, installation of an M32 on an engine exhaust is intended to bring the noise level down to match the ambient noise levels.
M42 Super Critical grade chamber type silencer, expected attenuation is 30 to 38 dBA. Quiet residential areas where background noise is relatively low and "critical" grade silencing is required.
M52 Hospital grade chamber type silencer, expected attenuation is 35 to 42 dBA. "Hospital" grade noise reduction in heavy industrial areas where machinery operates continously around quiet locality. Such as hospitals, shools and quiet residential districts.
M62 Hospital Plus grade chamber type silencer, expected attenuation is 35 to 50 dBA. Very high degree of silencing in areas requiring "hospital plus" noise reductions.

MD Series Low Profile Compact "Pancake" Chamber Silencers

Maxim's MD Series Low profile compact "pancake" chamber silencers are engineered to provide "critical" to "hospital" grade attenuation, while minimizing space usage. They are an excellent choice for packaged power and process skids where space is a premium. Dual inlets and other custom designs can be easily incorporated. Low temperature design not only reduces skin temperature, but radiated noise as well. These units feature heavy duty, welded construction with temperature resistant insulation within a double wall construction. The inlet and outlets are standard with ANSI drilled 125/150 lb flanges. Standard finish is high temperature resistant silicone black. Alternate finishes are available upon request. Standard material is carbon steel, but stainless steel construction is available.

MSA Series Chambered Spark Arresting Silencers

Maxim's MSA Series Spark arresting chamber style silencers. Spark arresting applications include marine service, refineries and other hazardous environments. These units have chamber type designs. The retention of hot carbon and soot particles minimizes danger and helps provide a cleaner area and atmosphere.
MSA11 Residential grade chamber type, spark arresting silencer, expected attenuation is 20 to 25 dBA. Residential and light industrial areas for spark arresting capability where background noise is relatively high and constant and the need for higher degrees of silencing is minimal.
MSA22 Critical grade chamber type, spark arresting silencer, expected attenuation is 25 to 32 dBA. Residential areas where background noise is present but not objectionable and a spark arresting feature is desired. Brings the noise level down to match the ambient noise levels.
MSA33 Super Critical grade chamber type, spark arresting silencer, expected attenuation is 30 to 38 dBA. Quiet residential areas where background noise is relatively low and "super critical" grade silencing with a spark arresting feature is required.
MSA44 Hospital grade chamber type, spark arresting silencer, expected attenuation is 35 to 42 dBA. "Hospital" grade noise reductions and a spark arresting feature. Presently the top-of-the-line reactive silencer without the addition of accoustical insulation.
MSA55 Hospital Plus grade chamber type, spark arresting silencer, expected attenuation is 35 to 50 dBA. High degree of silencing in areas requiring both "hospital plus" grade noise reductions and a spark arresting feature.

MT Series Low Pressure Drop/Turbo Silencers

Maxim's MT Series Low Pressure/Straight through silencers have an unobstructed passage through the silencer with no flow reversal. The result is a pressure drop across the silencer only slightly above that caused by an equivalent length of pipe. Side connections are not practical in this design due to an increase in pressure drop and price. Noise attenuation provided by straight through design is less than that provided by chamber design silencers incorporating a flow reversal. As a result, the MT series is best used in applications where low pressure drop is the primary consideration.
MT22 Residential grade straight through, low pressure drop silencer, expected attenuation is 20 to 25 dBA. Silencing in areas where background noise is relatively high and moderate silencing is needed and requirements call for a low pressure drop silencer.
MT32 Critical grade straight through, low pressure drop silencer, expected attenuation is 25 to 32 dBA. Average silencing in areas where some background noise is always present and effective, but not complete, silencing is needed and requirements call for a low pressure drop silencer.
MT42 Super Critical grade straight through, low pressure drop silencer, expected attenuation is 30 to 38 dBA. Better than average silencing in areas where ambient noise is relatively low and back pressure requirements call for a low pressure drop silencer.
MT52 Hospital grade straight through, low pressure drop silencer, expected attenuation is 35 to 42 dBA. "Hospital" grade noise reduction in areas where ambient noise is relatively low and back pressure requirements call for a low pressure drop silencer.
