[Collins] Boat Anchor Fans

Dave,
    I beg your pardon -- every bit of air that goes out thru the fan has to
be replaced by air coming into the cabinet.  That air can also carry dust.
Since it may be of lower velocity than the air passing thru the fan, it may
not carry as much dust as it would if the fan was blowing in, but it will
carry dust in.
    Unless Collins units have some special feature that I'm not aware of.
73,
Al, W8UT
New Bern, NC
