About this file
This is a Questions and Answers document related to a compressed air system installation or upgrade project. The document addresses contractor inquiries about existing facility infrastructure and equipment specifications.
The facility contains an existing compressed air system with 34 distribution drops configured as a loop system, served by 2 storage tanks located in Mechanical Room 11, Building 1235. The piping is copper (not steel), and both the drier unit and compressor can be removed. The existing Sullair air dryer operates at 460V, 3-phase, 60Hz with 2.7kW power consumption and 6A current draw. The air compressor breaker/fuse size is rated at 150A, 600V, though wire sizing is unknown and clarification is requested. An alternative Sullair compressor near the media blasting machines has the capability to supply the entire building with air but is currently shut off from the rest of the system; however, past attempts to connect it caused water flooding in the paint booth and blaster equipment. The contractor may alternatively remove the non-operational dryer and install a replacement dryer while piping in a tie-in for a diesel portable compressor, pending clarification on the diesel portable generator specifications. Access to the facility is limited to Monday through Thursday, conditional upon personnel not being dispatched to the missile field.

How many drops are there?
Is it a straight run or a loop system?
Loop System
How many tanks are there?
Can we remove the drier unit and/or compressor?
Yes. Old system Located in Mechanical Room 11, Bldg 1235
Can we cut the piping?
Yes
What schedule is the steel piping?
Piping is copper
Can you confirm the existing electrical data from the existing Sullair equipment?
Air Compressor:
Air Dryer: 460V 3 ~60Hz 2.7kW 6A
Compressor and dryer electrical info is needed as it is not listed in the Bid Doc. I need to know the voltage, breaker/fuse size, and wire sizing. Any and all data you can provide would help us quote this more accurately.
Breaker/Fuse Size: 150A 600V
Wiring Size Unknown
Can the Sullair near the media blasting machines could supply the entire building with air?
If that is the case could we hook up the air audit equipment to that machine? That would cut down on having to bring equipment in.
It was reported as “Yes, it has the capability. Its currently shut off from rest of the system.” CONCERN: When it was attempted to do this in the past, the Paint Booth and
Blaster flooded with Water.
QUESTION: If this option is chosen will it cause a stoppage using the existing equipment ie, Paint Booth and Blaster?
LIMITING FACTORS: Access is Monday thru Thursday provided personnel are not dispatched to missile field.
If that is not an option, we will need to know if we can remove the non-operational dryer and install a dryer in its place as well as pipe in a tie in for a diesel portable compressor.
Yes. CLARIFICATION Requested for the diesel portable generator
