SUBJECT : Request for Support - Remote Location of Vacuum Pumps
1. OIA expects delivery of a new comparator about March 15, 1978.
A key component of this comparator is a small pump which generates
vacuum for the film hold-down?system. While every effort has been made
to insulate and isolate, the noise generated by this pump, the noise
level remains unacceptable for normal office conditions. Thus, this
pump must be installed emote location, outside any occupied
STA INTL office spaces in STATINTL
2. has been the subject of considerable discussion
STA INTL between OIA `s photo ranunetri st and
of the Logistics ranc , SS/NPIC. have ATINTL
STATINTL limmediately adjacent to the east wall of STATINTL
3. The installation of the pump will require running a one inch
diameter vacuum line of a rigid material (either hard copper or PVC
pipe) from the pump site to the comparator located in Room 3N180 (see
floor plan, Attachment 1). An electrical conduit running parallel to
the vacuum line will be required to carry the necessary wiring to
monitor and control the pump from the comparator console. A 220V
service will be required at the pump location.
4. The path that the vacuum and control lines would take from the
pump to the comparator seems to be un-obstructed. The lines would leave
the comparator and run through the ceiling space from Room 3N180 to the
STA INTL east wall of They would then ass through the wall and STATINTL
run straight down a in erior wall of Ito the ground level
pump location (see Attachment 2).
5. We realize that we are giving you rather short notice on this
problem. We first became aware of the need to remotely locate this
vacuum pump during the pre-acceptance tests conducted at the contractors
facility during the week of 30 January-4 February. The film hold-down
system on the comparator was redesigned, which required a higher capacity
vacuum pump than originally planned--with the higher capacity pump came
the noise pollution problem. .,We expect delivery of the comparator on
15 March, with acceptance testing scheduled for the week of 20 March--we
would greatly appreciate it if the vacuum and control conduit lines
could be available by 20 March.

6. On a separate, but related problem--as you may know, OIA now
has one comparator in use with a vacuum pump (of a smaller capacity)
remotely located in an interior hallway. Although this pump is smaller
and considerably quieter than. the large pump discussed above, it gen-
erates an objectionable noise the hallway and adjacent offices.
Relocation of this pump to ould be highly desirable, and
It appears that this could a one in conjunction with the installation
of the new pump at only a small increase in cost. Both pumps are
physically small and it appears feasible to use shelving to install one
above the other so that no additional floor space would be needed in
Unfortunately the comparator designs dictate the use of indepen-
en solated vacuum sources,,so that use of a single large vacuum pump
for both comparators is not possible. The second pump will require a
separate vacuum line and control conduit running parallel to those
installed for the larger pump discussed in paragraphs 3 and 4 above.
The smaller pump also requires a 110V service at the pump location. If
you agree on the feasibility of collocating these two vacuum pumps,
please include the relocation of our present pump in the work orders for
Installation of the new pump.
7, assistance and your support in the solution of
these problems, particularly in view of the rapid response required, is
greatly appreciated.
