Selected catalogue reference

QSI-150 is a Quincy fixed-speed rotary-screw compressor. Its 150 hp / 110 kW source entry has separate pressure/flow rows below; these are individual published duties rather than a continuous operating envelope.

Published pressure/flow pair

769.0 ACFM with pressure column 110/110 PSI

ACFM and PSI retained exactly as printed; no SCFM conversion, intermediate duty or cross-row combination inferred. Slash-separated pressure notation is not defined by this sheet; no rated/max-pressure interpretation or selection interval is assumed.

Published pressure/flow pair

678.3 ACFM with pressure column 125/128 PSI

ACFM and PSI retained exactly as printed; no SCFM conversion, intermediate duty or cross-row combination inferred. Slash-separated pressure notation is not defined by this sheet; no rated/max-pressure interpretation or selection interval is assumed.

Power

150 hp; 110 kW

Power columns as printed; motor rating versus total package input is not independently established.

Weight

7186 lb

Published package row; final execution and transport requirements need confirmation.

Sound level

74 dBA

Printed dBA row; measurement distance/load basis not fully specified here. No site noise guarantee.

Reference applications

• Industrial compressed-air generation at the selected pressure and flow.
• Steady-demand compressed-air systems.

Reference technical notes

• The length, width and height columns do not state units. Do not assume the dimensions are in inches.
• Electrical voltage/phase/frequency and exact installed configuration require manufacturer confirmation.
• Confirm the meaning of the paired QSI pressure values before selection.
