Sound Enclosure
D Sound level (8 point logarithmic average) at 7 m (23 ft.) with full load:
73 dB(A).
D Sound level compared to competitor ratings with no load: 70 dB(A).*
D Sound attenuating enclosure uses acoustic insulation that meets
UL 94 HF1 flammability classification and repels moisture absorption.
D Vertical air inlet and outlet discharge with 90 degree bends to redirect
air and reduce noise.
D Internal-mounted critical silencer and flexible exhaust connector.
D Skid-mounted, steel (standard) or aluminum (optional) construction
with hinged doors.
D Fade-, scratch-, and corrosion-resistant Kohlerr Cashmere Power
Armort textured e-coat paint.
D Lockable, flush-mounted door latches.
D Certified to withstand 241 kph (150 mph) wind load rating (aluminum
enclosures only).
* Lowest of 8 points measured around the generator. Sound levels at
other points around generator may be higher depending on installation
parameters.
