SUPERTRAPP SPARK: ARRESTOR MUFFLERS

Specifications
SuperTrapp’s patented “diffuser disc” design cuts noise and traps hot sparks in a system that is quieter,
smaller and lighter than any other spark arrestor or compact muffler.
The exhaust outlet is formed by stacking the individual diffuser discs to form a series of annular openings.
The precise spacing between the discs provides a barrier against noise and sparks without restricting the
exhaust flow. The number of diffuser discs required is proportional to engine size. The exhaust noise will be
minimized when the least number of discs is used.
As the exhaust flows out radially between the discs, the noise is first dissipated and then diffused over a
quiet 360 pattern. After leaving the discs, the exhaust path curves inward toward the centerline and is rapidly
cooled by mixing with the surrounding air. Only 1/2” side clearance is quires between the disc’s outer edge
and any heat sensitive areas.
SuperTrapp is the only U.S.D.A. Forest Service Approved spark arrestor without restrictive swirl baffles
or fragile screens. Hot sparks are propelled directly into the collection chamber (end cap) by the natural
exhaust flow momentum. The 0.023” spacing between the discs gives back–up protection should the
chamber fill to capacity.

Q
uiet—Less than one-half the exhaust noise level of any other spark arrestor or compact muffler
(over 6 dbA quieter). Optional Resonator available for additional 4 to 6 dbA reduction.
Compact—Less than one-half the size and weight of all non-screen type spark arrestors.
U.S.D.A. Forest Approved—Rated at 99.4% spark resting efficiency (80% required).
Multi–Position Rated—Approved by U.S.D.A. Forest Service for any mounting position.
Rain Protected—No mechanical flapper caps required.
Cooler Exhaust—Radial exhaust flow quickly mixes with surrounding air to reduce exhaust
temperature 300 F compared to conventional designs.
Durable­—All stainless steel and heavy gauge steel construction for rugged service.
Rebuildable—Modular construction allows individual components to be replaced.

U.S.D.A Forest Approved
Industrial Model 3S
Model 3S adapts to a wide range of engines from 2 to 50 HP. Recommended for engines to 10 HP where
minimum exhaust noise is required and for larger engines where space is limited. Supplements an existing
muffler where minimum exhaust noise is critical. U.S.D.A. Forest Service Approved spark arrestor No. T–100.
Industrial Model 5S
Designed for engines from 10 to 200 HP. Recommended for engines from 10 to 100 HP where minimum
exhaust noise is required, and for larger engines where space is limited. Supplements an existing muffler
where minimum exhaust noise is critical. U.S.D.A. Forest Service Approved Spark Arrestor No. T–101.

Applications:
Use approximately 1 Disc
per 3 HP on Model 3S.
The following graph relates
the number of discs used
to the resulting back–pressure.
Using 1 disc per 3 HP
insures that the back–pressure stays within the engine
manufacturer’s recommendations. The resulting back–
pressure will not significantly affect power.
4–cycle engines will tolerate a back–pressure considerably higher than 2 psi
without endangering the engine.
The accessory Resonator (part no. 3S–5500) is recommended if
further exhaust silencing is required (3 to 5 dbA added reduction).
For critical noise applications reducing the number of discs used is
suggested, but some power loss may result. In addition, engine
shielding or an engine enclosure will be required to reduce other
engine and mechanical noises to that of the silenced exhaust.
The number of discs used may need to be increased if SuperTrapp is
added to an existing muffler or if used on an engine rated below 2400
rpm. Engines with dual exhausts should divide the
recommended number of discs by 2.
Applications:
Use approximately 1 Disc per
7 HP on Model 5S. The following graph relates the number
of discs used to the resulting
back–pressure.
Using 1 disc per 7 HP insures
that the back–pressure stays
within the engine manufacturer’s recommendations. The
resulting back–pressure will not
significantly affect power. 4–cycle engines will tolerate a back–
pressure considerably higher
than 2 psi without endangering
the engine.
The accessory Resonator (part
no. 5S–5500) is recommended if
further exhaust silencing is required (4 to 6 dbA added reduction).
For critical noise applications reducing the number of discs used
is suggested, but, some power loss may result. In addition, engine
shielding or an engine enclosure will be required to reduce other
engine and mechanical noises to that of the silenced exhaust.
If SuperTrapp is added to an existing muffler or used on an engine
rated below 2400 rpm, the number of discs should be increased
(doubling the recommended number of discs will ensure a negligible
change in the original exhaust back pressure). Engines with dual
exhausts should divide the recommended number of discs by 2.
