Barrier Filter System
A Better Solution
Supplemental Type Certified (STC’d) for the Hiller 12E and Bell 47 Soloy Turbine Engine conversions, Cascade’s Barrier Filter System for the helicopters replaces the currently used particle separator. Bleed air from the engine compressor is disconnected and plugged, as the barrier filter system doesn't require its use.
Cascade’s system utilizes ambient temperature air and doesn't rob bleed air from the engine, resulting in a lower TOT and more usable power.
Allows the compressor air to be used by the engine enhancing its performance
Air formerly from the compressor, used by the particle separator, was hot and increased the temperature of the intake air further reducing the efficiency of the engine
Improved Performance
Cascade barrier filtration system offers increased performance and reduced operating costs extending the life of your turbine investment.
Reduced TOT of 25 to 35 ºC , testing results of the system showed a 43 ºC reduction in ITT temperature on a static test pulling full torque
Pull full torque at lower ITT temps
Reduced fuel burn
Extend the life of critical turbine parts
Long lasting serviceable Air Filter System
60% more surface area than conventional filtration systems
15 minute filter change time
“We saw an immediate 30-degree Celsius drop.”
“The last 14 years of compressor inspections have been impeccable.”
“Installation of the CAC inlet barrier system was a day job for one mechanic.”
