Royston Family has been involved with the rotary positive
blower industry since 1954.
It was at this time that Mark Royston started as a
sales engineer for the Sutorbilt Corporation.
In 1959 he started a company called Pacific
Pneumatics which began as representative for Sutorbilt in
Southern California and grew to be a packager of blowers and
supplier of products allied with the positive displacement
blower industry. His
wife, Doris, learned the intricacies of the industry as she
did the background work of phone answering, preparing the
quotes, doing the follow up and all the other necessities of
running a business.
Along the way knowledge was gained that helped in the
analysis of blower applications and the selection of the
best blower for the job, albeit, at the time limited to the
blower that was being represented.
Knowledge of competitorís products led to knowledge
of the overall industry.
The Royston family grew with the addition of five
children and as they aged, each learned about the business through early activities, which in most
cases started with cleaning the offices and bathrooms on the
went their way to a career in the world of blowers, and
what makes up the Royston Group.)
Certainly the single largest application for a
positive displacement blower over a long period of time is
pneumatic conveying. As
this industry grew, the Royston individuals involved,
through trouble shooting problems in many cases, gained a
knowledge of that industry until a formula was developed
that would help size a system if the parameters were known. The first step toward a computer program was the putting of
this formula onto a HP-300 engineering calculator in the
early 1970ís. In
the late 1970ís a patent was obtained by Mark Royston for
a scaling device that would sense the pressure in the system
and after calibration, report out the conveying rate. This formula had its limitations as it was devolved from
empirical data and required conveying
a sample amount through the system and adjusting the
formula constant to equate the output reading to agree with
the amount conveyed. This system, while a step forward, needed the advent of
modern computers and the accompanying software, to make it a
practical product. The
new scaling system (See IDPI, Industrial Data Processing for
details) uses sophisticated mathematics
and eliminates the need for a sample amount of
product to be conveyed.
The Royston family members were forward thinking and
were on the leading edge of computerized programs for the
sizing of positive blowers and the comparison of the results
with more than one blower manufacturer.
