The AFS Bell 206B (OH-58A/C) Inlet Barrier Filter (IBF) provides the optimum performance possible within the existing Bell cowling, utilizing two filters with a top access door for ease of maintenance. The flat filter assemblies are mounted just left of the aircraft’s bifurcated engine air inlet system in the same location and in lieu of the Engine Air Particle Separator (EAPS) or Air Induction Screen (FOD Screen). The IBF installation requires minimal modifications to the existing air inlet cowl assembly without impacting the integrity of Bell’s forward firewall. An access panel on the top of the air inlet cowl allows the operator quick access to the filter for servicing without removal of the cowl. Engine water wash provisions are provided with the new IBF and function the same as the original Bell system; the filters do not require removal to perform the water wash. A Self contained bypass system is provided with a cockpit annunciation and activation switch along with a Filter Maintenance Aid (FMA) for on condition monitoring of the filter condition. The AFS IBF system provides dust, sand, and dirt separation efficiencies exceeding 99% to insure your engine has the maximum protection possible. This IBF system is available as a factory direct option on the Bell 206B.

Introducing a new unique Agusta A119 Inlet Barrier Filter (IBF) system featuring an innovative lightweight and simple to install option in lieu of the significantly less efficient Engine Air Particle Separator (EAPS) or FOD Screen. The IBF system literally slips into the current engine inlet fairing location with minor aircraft modification. The lightweight assembly with three flat filters are designed to perform with ultimate efficiency in all flight regimes. The significant amount of filter area allows cleaning service cycles as long as 300 hours (service life is a function of the operating environment) and no performance restrictions using basic inlet charts. A self contained bypass system is provided with a cockpit annunciation and activation switch along with a Filter Maintenance Aid (FMA) for on conditioning monitoring of filter condition. An aft facing bypass door ensures that dirt and snow do not enter the inlet allowing flight in all environment conditions without restrictions.

Flat filter assemblies make servicing a snap, and the filters can be removed and replaced in 15 minutes. The design of the AFS A119 system allows quick and simple installation in exactly the same location as the existing FOD screen. The AFS IBF system provides dust, sand, and dirt separation efficiencies exceeding 99% to insure your engine has the maximum protection possible.

AFS commercial products are available direct from AFS, through our distributor network or as a factory direct option from AgustaWestland.

Introducing a new AFS Eurocopter AS350 (AS350B/BA/B1/B2/B3/D/SD/SD2) Inlet Barrier Filter (IBF) system with an innovative, lightweight and simple to install design approach which literally allows fit up with the engine cowling. The design of the system allows quick and simple installation without reworking the existing cowling. The canted flat filter is designed to perform with ultimate efficiency in all flight regimes. A self contained bypass system is provided with a cockpit annunciation and activation switch along with a Filter Maintenance Aid (FMA) for on condition monitoring of filter condition. The significant amount of filter area allows cleaning service cycles as long as 300 hours (service life is a function of the operating environment) and no performance and operation restrictions. A rugged flat filter assembly with quarter turn fasteners makes servicing a snap; the filter can be removed and replaced in 5 minutes. An aft facing bypass door ensures that dirt and snow do not enter the inlet and allows flight in all environment conditions without restrictions. The AFS IBF uses 95% common components for any AFS AS350 model including the Soloy Super D conversions. Therefore, you don't have to worry about costly add-ons or a different IBF system for your mixed Turbomeca or Honeywell powered fleet. The AFS IBF system provides dust, sand, and dirt separation efficiencies exceeding 99% to insure your engine has the maximum protection possible.

AFS commercial products are available direct from AFS or through our distributor network.

Introducing a new unique Bell 205 (205A1/A1++, UH-1H) Inlet Barrier Filter (IBF) system that provides a high performance filtration option versus the significantly less capable Engine Air Particle Separator (EAPS) or Improved Particle Separator (IPS). The system features a dual entry inlet with four interchangeable filters. The significant amount of filter area allows cleaning service cycles as long as 300 hours (service life is a function of the operating environment) and no performance restrictions using basic inlet charts. The IBF System is mounted just aft of the aircraft's main rotor mast in the existing air inlet system in lieu of the EAPS, IPS, or FOD Screens. The IBF installation requires minimal modifications to the aircraft and provides a new forward firewall interface along with significantly improved drive shaft access.

Engine water wash provisions are provided with the new IBF and function the same as the original system; the filters do not require removal to perform the water wash. A self contained bypass system is provided with a cockpit annunciation and activation switch along with a Filter Maintenance Aid (FMA) for on conditioning monitoring of filter condition. The AFS IBF system provides dust, sand, and dirt separation efficiencies exceeding 99% to insure your engine has the maximum protection possible.

AFS commercial products for applicable Bell model helicopters are available direct from AFS or through our distributor network.
