General Information
IntroductionSelecting a silencing solution for your application is simple. There are two methods used to make the selection:
• Use Method 1 when the pressure drop requirement is greater than 1.0 inches Hg (approximately 13.62 inches H2O).
• Use Method 2 when the Pressure Drop requirement is less than 1.0 inches Hg (approximately 13.62 inches H2O).
Determining the Exhaust Flow RateRegardless of the method you choose, you will need to know the Exhaust Flow Rate. If this value is not known, use the following equation to estimate the Exhaust Flow Rate, then proceed with Method 1 or 2 to select a silencing solution.
D × Full Load RPM × E × (T + 460°) C x 941,760where:
D = Displacement in in3
E = 0.85 efficiency for naturally aspirated engines = 1.2 for engines with scavenging blower = 1.4 for turbo-charged engines
T = Exhaust temperature (if unknown, use 900 °F (482 °C) for diesel and 1,200 °F (649 °C) for gas engines)
C = 1.0 (one-cycle engine) or 2.0 (two-cycle engine)
Estimated Exhaust Flow Rate =
Selecting a Silencing Solution
nelsonglobalproducts.com1-4
General Information
Method 1You must know the following information:
• Exhaust Flow Rate (ft3/min (m3/min))• Silencer Inlet Area (ft2 (m2))• Level of Silencing Required1. Calculate the Exhaust Gas Velocity Exhaust Flow Rate (ft3/min (m3/min)) Silencer Inlet Area (ft2 (m2))
2. Find the Estimated Pressure DropUsing the Exhaust Gas Velocity you just calculated, find the corresponding Estimated Pressure Drop in the “Typical Pressure Drop Curves” column on pages 1-6 and 1-7.
3. Select a SilencerSelect a silencer that achieves your silencing level requirements at an acceptable Pressure Drop level.
Example:1. Given: Exhaust Flow Rate is 2352 ft3/min (66.60 m3/min )
Silencer Inlet Area is 6" (152 mm) diameter which equals 0.196 ft2 (0.018 m2) Level of Silencing Required is Critical Grade
2352 ft3/min (66.60 m3/min) 0.196 ft2 (0.018 m2)
3. Using the Typical Pressure Drop Curve, find the Estimated Pressure Drop using the Exhaust Gas Velocity. For this example it is approximately 20 inches H2O (1.49 inches Hg).

Velocity should not exceed 15,000 ft/min (4572 m/min) regardless of the allowable back pressure (10,000 ft/min (3048 m/min) for spark arresting silencers).
What Else Should I Know?Nelson Global Products exhaust silencers provide optimum performance for all applications by offering silencers crafted for four different attenuation grades. Due to the variability of different applications, performance levels are most accurately shown as broad range “expected attenuation bands,” which are based upon typical conditions. These bands will not define the exact insertion loss for a specific application, since insertion loss is influenced by engine size, type, speed, and unsilenced noise levels (see product spec sheets for attenuation, back pressure, and design details).
Note: Keep in mind that silencers are not designed to support their weight from the inlet or outlet tube, or support other components of the exhaust system, such as stacks. For the most efficient operation of all silencing units, proper mounting attachments are required.

General Information
IntroductionDrains are standard on all models with a 9" (229 mm) O.D. or larger. Models with a 26" (660 mm) O.D. or smaller have a coat of high heat-resistant paint. Models larger than 26" (660 mm) O.D. have a rust-inhibiting primer under high heat-resistant paint. Maximum operating temperature is 1,250°F (677 °C) for aluminized units. Heat-resistant paint maintains its properties up to 900°F (482 °C) on aluminized steel and 1,100°F (593 °C) on mild steel.

Note: When figuring Pressure Drop for side or middle side inlet units, add 3 inches H2O (0.22 inches Hg) to back pressure shown on curve.
• Space Saver silencers are designed for side in, end out mounting, although either end can be used as in inlet. Using end in, side out can result in lower attenuation reductions.
• Condensate drains are standard on all units.

BenefitsInsulation blankets on diesel exhaust systems offer the following benefits:
• Reduce external system surface temperature by as much as 1,000 °F (538 °C)
• Silence sound by as much as 3 dB• Substantially reduce heat transfer into buildings
and enclosures• Multi-use – remove and reuse on other diesel
exhaust systems
About the BlanketsNelson Global Products brand insulated blankets are constructed of three unique plies:
Inside Ply is made of a knitted stainless steel wire mesh
Middle Ply is a Type E fiberglass insulation*
Outer Ply is made from silicone-impregnated fiberglass fabric
High-temperature resistant silicone provides significantly longer life and improved resistance to abrasion, flexing wear, tears, and punctures. The heavy-duty inner lining fabric is resistant to oils and acids/alkalis, as well as being flame retardant.
All blanket edges are machine-stitched using high grade fiberglass thread and fastened with permanently mounted stainless steel hooks. The blankets are laced in place “boot-style” with stainless steel tie wire, resulting in a custom-made “glove fit.”* Type E fiberglass insulation is designed for insulation within high-
temperature equipment. It is manufactured from chopped fiberglass fibers and is free of resinous binders, which enables its use in the high-temperature ranges. Type E insulation is flexible, lightweight, and will not compact under vibration.
SpecificationsEach insulation blanket conforms with the requirements of Military Specifications MIL-I-164-E, Type II.
