Inlet Barrier Filters, Any Experience Good Or Bad?

[bugdriver]

Has anyone out there had any experience with Inlet Barrier filters ( FDC aerofilters for example) whether good or bad?

We are looking at an application for Bell 206L1 C28 engine, which at this time we are unsure if it is even possible to install on the L1.

Any thoughts?

Love em on our Astars. Compressors and turbines look like new even after landing in sandy places all summer. Easy and quick to clean. A couple problems with the microswitches on the alternate air door system, but pretty simple to fix.

Flew an A-star with a barrier filter in very dusty conditions in Sask. a few years ago. Learned to avoid the worst dust when the filter got clogged after the first week. Can only imagine the compressor damage we avoided! Also had some grief with an alt air door servo motor. Checking them's now a regular part of my DI.

 

Cheers,

They work great, our 407, the year before we installed it went from a +20 eng to a barely passing engine in one season in the arctic. After installing the filter, there is minimal decrease in performance over 2 years in the same place. It is also installed in our 206L1 with the C30 eng. The only thing I would suggest is to buy a spare filter, so when the first gets dirty you can clean the other over a couple of days and do a real good job.

We run them in most of our A-Stars.

Very highly recommend it.

 

As stated earlier, buy a spare filter for each installation.

That way, you can do the cleaning and servicing at your convenience and don't lose any down-time.

If you have a choice between AFS and FDC go with the AFS its a much better product.

Excellent, thanks for the input, especially the spare filter idea.

Stick with AFS if you want any service or parts. Also a whole lot cheaper to operate and far less installation problems. Any one have info on 350 seals coming off FDC kits and winding up in the engine. Heard VIH had one

Which seal?

[RedRag]

I think one on the bottom of the filter inside the housing. Pretty sure it was VIH but I'm getting old.
