FOR IMMEDIATE RELEASE

Rapco, Inc. has now received FAA-PMA Approval on the RA215CC / RA216CW and RA441CC / RA442CW
vacuum pumps. These pumps are available in all the different style dash numbers. See Insert box for a list of the
different styles:

Rapco, Inc. has improved the performance of these pumps by incorporating a new internal cavity design that has
precision laser cut air ports improving the overall air flow. In addition, we have equipped each pump with an
advanced internal rotor that has a bevel on the inlet side of each rotor vane. This allows some small particles to pass
through thepump without failure. The new pump also has an exclusive internal teflon coating to improve carbon vane
wear. To prevent premature pump damage, a unique inlet screen is provided, free of charge with each pump, that fits
into the inlet pump fitting preventing most foreign particles from entering the pump.

Please note that there is no core charge on this new pump. In each pump box is a rebate coupon that allows the
installer to return the old core for a rebate check. This provides for easier handling of cores and still insures that we
have an adequate number of cores left over for the overhaul program. We will continue to overhaul the 211CC,
212CW, 215CC, 216CW, 441CC & 442CW series pumps and now we will add the new pumps to our
overhaul process!
