A Quality System Starts With Quality Components
......
Phase 1 -
Oil Removal - Not all coalescing filters are alike. Some work
significantly better than others. The filter that we selected was chosen because
independent laboratory test verified its performance. it represented the optimum
mix of filtration efficiency, durability and serviceability.
Guaranteed element life: One (1) year.
Residual oil carryover: 0.002 parts per million

Phase 2 -
Water Removal - In addressing this problem, we knew that old existing
technologies were simply not working. Many dental offices we visited were
experiencing serious water problems in their compressed air, even though
"dryer" were installed. Dew points lower than refrigerated types can
produce are needed to totally eliminate moisture. Traditional desiccant type
dryers can achieve very low dew points, but they are very expensive and not
practical. The ultimate solution would be a dryer with dew point performance
like a desiccant type, and a cost structure like a refrigerated type. Guess what
--- We did it!

Phase 3 -
Hydrocarbon Removal - Many people chose to ignore this contaminant. They
really shouldn't. The hydrocarbon are what make the air supply smell bad and
taste funny. The critical design consideration in an activated carbon type
filter is the effective life of the filter media. This is purely a function of
the surface area. We chose a filter media with tremendous surface area -- in
fact, three (3) times as much surface area as any other filter normally supplied
for this application. The result is outstanding performance and
exceptionally long service life.
Guaranteed element life: One (1) year.
Residual Hydrocarbons: 0.001 parts per million

Phase 4 -
Pathogen Removal - In addressing this problem
our task was significant ! Existing membrane filter technology proved to be
inadequate. A new approach was required. The solution after years of development
is Virex®.
Virex® is a sophisticated
ultra filtration membrane that is specifically designed for applications
requiring the purest of air. First, the effective pore size of our membrane is
exceptionally small -- 0.04 micron. It is also exceptionally uniform. Pore size
and uniformity are critical in determining the size of the pathogens that a
membrane can filter.
Secondly, the Virex® element
can be very easily changed, and more importantly -- safely changed. The element
can be handled without ever having to touch the contaminated filter surface.
This benefit does not occur with traditional membrane filter designs. In
traditional designs, it is necessary to actually touch the filtration surface in
order to remove the element from its housing.
Finally, because of its
innovative construction, Virex® has an extraordinarily large surface area. This
results in a very high contaminant-holding capacity which in turn allows for
extended change-out intervals.
All Virex® element are
manufactured in a "Clean room" in accordance with FDA approved Good
Manufacturing Practices. Each element is stringently tested prior to shipment.
Guaranteed element life: One (1) year
Membrane pore size: 0.04
