Engine Exhaust Silencers

Engine Exhaust Silencers

Universal brand exhaust silencers provide the most favorable 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 untreated noise levels.


Silencers for Small Spaces and Critical Applications



"Puck"-style silencers are low-profile silencers that not only fit in the smallest enclosures, but are also ideal for portable power, marine, or other applications where a "tight fit" is a concern. The single inlet models are available in residential, critical and hospital attenuation grades. Critical and hospital models also offer a low skin temperature (LST) design for exceptionally small compartments and enclosures to keep radiant heat to a minimum. The LST configuration incorporates an extra layer of packed acoustic/thermal insulation that reduces heat and noise, eliminating the need for expensive external wraps. The aluminized steel designs far outperform the comparably priced carbon steel competition by offering higher corrosion resistance, greater maximum operating temperatures, less weight and an overall longer silencer life. Puck silencers are available in single-inlet, and four types of duel inlet models.

Silencers for Existing Exhaust Systems

Standard spark arresters are designed for general applications with a minimum of restriction on the engine, and are ideal as add-on units to existing exhaust systems. The arresters' light weight and small size reduce stress and vibration to the rest of the exhaust system. Typical applications include logging and construction equipment, agricultural machinery, over-the- road trucks, airport equipment, forestry, and military vehicles.



Case studies

Space Saver



Space Saver units are designed for side-in end-out mounting, although either end may be used as an inlet. Using end-in side-out may result in lower attenuation reductions. Condensate drains standard on all units.

Spark Arresters, Non-Silencing



Standard spark arresters are designed for universal application with a minimum of restriction on the engine, and are ideal as add-on units to existing exhaust systems. The arresters' light weight and small size reduce stress and vibration to the rest of the exhaust system. Typical applications include logging and construction equipment, agricultural machinery, over-theroad trucks, airport equipment, forestry, and military vehicles.

Spark Arresting Silencers, Type 1



Standard Spark Arresting Exhaust Silencers provide high efficiency spark arresting and exceptional sound attenuation where fire hazards must be eliminated and noise must be minimized. Three attenuation grades (industrial, residential, and critical) are available with spark arresting efficiencies exceeding 95%. Heavy gauge material and fully welded construction provide maximum strength and longer service life in these units. Applications include stationary and portable gen sets, oil field equipment, propulsion engines on ships, and gas compression equipment.

Spark Arresting Silencers, Type 3



Standard Spark Arresting Exhaust Silencers provide high efficiency spark arresting and exceptional sound attenuation where fire hazards must be eliminated and noise must be minimized. Three attenuation grades (industrial, residential, and critical) are available with spark arresting efficiencies Male pipe thread connections through 3.5", 4", and larger are 125/150# ASA drilled flanges. Drains are standard on all silencers with a 9" body diameter or larger. Side-in end-out configuration is designed for side inlet flow only. Unit cannot be run backward. All dimensions are in inches. exceeding 95%. Heavy gauge material and fully welded construction provide maximum strength and longer service life in these units. Applications include stationary and portable gen sets, oil field equipment, propulsion engines on ships, and gas compression equipment.

EN Series Multi-Chamber Silencers



For the majority of engines and operating conditions, multi-chamber type silencers provide maximum noise attenuation within acceptable back pressure limits. Most naturally aspirated and supercharged engines need this type of silencer. Many turbocharged engines are best silenced with this design also.

ET Series Straight-Through Silencers



Some engines require very low exhaust system back pressures for maximum performance. Many turbocharged engines and some naturally aspirated engines fall into this category. For these engines, straight through, reactive silencers are available to provide adequate silencing while imposing negligible restriction on exhaust gas flow.

ES Series Spark Arresting Silencers



Operating locations exist where fire hazards and safety codes require removal of sparks from exhaust gases. Universal's spark arrestor silencers are engineered to perform the dual function of spark arrestment and silencing for all internal combustion engines.
