Hawker's Filter System
In
1997 I asked Wayne to build me a set of his filters. I had seen a
few of his earlier designs and felt they had a few issues I wanted
fixed. What I did was converse these issues to him and he
improved his design to deal with these issues. What I have is his
first revision of the third generation filters. The improvements
allow for higher pressure use and easier chaining of the filter.
I also added my own air blead system after I found issues with his
system. These improvements became to basis for all his later
systems. The systems require some custom maching and a special
thread tap making them hard for others to manufacture. What I
intend to do here is show the parts and construction of the filters to
educate the user about the parts and issues in the hopes that we can
design the next generation of filters. At the end of this page I
will give thoughts and ideas on where this is heading.

The #4 (also known as a 1040) filter used in these pumps is amazing in
it's ability to provide clean water. It is cleanable providing long
life, filters to 0.2µ absolute, and is relitivly
inexpensive. What we needed was a housing we could connect this
filter to and use our existing gravity fed delivery system
with. To the rescure came Wayne Roby. Wayne did the initial
research and prototyping. He developed several custom systems
using the #4 filter that evolved over time. I currently own two
of his latter generation high pressure housings. Sadly we have
lost touch with Wayne and are no longer able to use him as a resource
for housings.
