SuperTrapps’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
to form a series of annular openings. The precise spacing
between the disc provides a barrier against noise and sparks
without restricting the exhaust flow while 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 required
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 .23” spacing between the discs gives back-up protection
should be chamber fill to capacity.
