Aerospace Filtration Systems (AFS) has received a Supplemental Type Certificate (STC) from Transport Canada (TC) for an Inlet Barrier Filter (IBF) system for the Eurocopter EC130 B4 and Eurocopter AS350B3 helicopters with dual hydraulic systems installed.

The approval clears the way for Canadian Eurocopter operators to maximize engine protection while reaping performance and maintenance benefits from proven AFS technology. European EASA approval is also in process, extending the AFS IBF solution to more operators.

AFS Inlet Barrier Filter systems are already in use by AS350 and EC130 operators worldwide, performing law enforcement, air medical, firefighting, news gathering and utility missions.

"This important Transport Canada certification gives individual and mixed fleet operators the ability to equip their helicopters with the best engine protection available," said AFS Business Development Director Robert Stenberg. "AFS AS350/EC130 IBF-equipped aircraft can also operate to the basic inlet performance charts thanks to no inlet driven flight or gross weight restrictions, and pilots have the option to use the sand filter performance charts when required."

The AFS system features a sealed intake plenum that replaces the inlet screens, sand filter/particle separator or alternate barrier filter. Design of the IBF allows easy installation, utilizing the existing cowl with no lateral cowl cuts required.

The filter and aft-facing bypass system are flush with the upper surface of the EC130 or B3 dual hydraulic cowling, utilizing an internal bypass plenum. An intake bypass capability is an important IBF feature that is lacking in most traditional sand filters and particle separators.

All electrical components are easily accessed from inside the cowling with minimal installation effort. A simple compact cockpit switch, common with existing AFS certified systems, allows indication and activation of the bypass system. And as with all AFS IBF's, an integral Filter Maintenance Aid allows for on-condition inspections between established cleaning intervals, eliminating unnecessary service.

AFS is the industry leader in the design, development and manufacture of high-performance engine IBF systems for commercial and military propulsion systems.

The company manufactures certified IBF solutions for the Eurocopter AS350 B/BA/B1/B2/B3, AS350's with Soloy or Heli-Lynx Honeywell engine conversions, EC130; AgustaWestland A119, AW119Ke; Bell 205A1, 206B, 407, 206L-3/4, 206L-1(C30); MD Helicopters MD 369H Series, MD 500D/E/F and MD 900/902. IBF systems for the Bell 430, AgustaWestland AW109E/S and AW139 are in development.

AFS is a wholly owned subsidiary of the Donaldson Company, Inc. Traded on the NYSE under the symbol DCI, Donaldson is a member of the S&P MidCap 400 Index. Additional company information for AFS and DCI is available at www.afsfilters.com andwww.donaldson.com.
