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 ch arts. 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) forconditioning 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.

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 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.
