Vent Silencer

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the SPMYM326Q3113 Vent Silencer opportunity, as of Amendment 03.

• Flow Rate & Design Limits: Vendors questioned the "12,000 SCFM (or more)" specification. The government clarified that silencers are designed to a maximum capacity and will not handle flows exceeding this design limit, as doing so could lead to failure. Specific design flow rates and maximum air flow through the vent or control valve need to be advised by the vendor to ensure proper quoting.
• Pressure & Temperature: Clarification was sought on the maximum air pressure and temperature upstream of the vent or control valve. The specification notes "125 PSIG (or greater)" and "-5 deg F or less." Vendors need to provide this information for accurate quoting.
• Intermittent vs. Continuous Vent: The nature of the vent (intermittent or continuous) was questioned.
• Noise Measurement Distance: The distance at which the 85dBA noise level should be calculated needs to be specified (e.g., 3ft, 5ft, 20ft).
• ASME Code Application: Clarification was requested on whether Note 3 (Max 120 psig inlet pressure) and Note 8 (ASME Section VIII, Div. 1 code diffuser) require the components to be created and maintained at the specified pressure/code or simply designed to it. The response confirms the requirement is to be designed to 120 PSIG and designed to ASME Code Section VIII, Div. 1.
• System Configuration: It was clarified that the silencer is downstream of a throttle valve, not a relief valve. The estimated flow rate at the silencer inlet is 10,500 SCFM at 45 PSIG, with an inlet pressure upstream of the valve at 1500 PSIG.

Vendors are advised to review the "Material Specifications" for updates related to these clarifications. The provided answers clarify design parameters and system configuration, which are crucial for preparing accurate quotes and ensuring compliance with technical requirements.

Questions & Answers / Clarifications

This document provides responses to vendor questions regarding the SPMYM326Q3113 Vent Silencer opportunity, as of Amendment 02.

• Flow Rate: Vendors questioned the "12,000 SCFM (or more)" specification. The responses indicate that updates to the Material Specifications address this, but the exact design flow rate requires clarification.
• Pressure and Temperature: Questions were raised about the maximum air flow, and the pressure and temperature upstream of the vent or control valve. Responses again refer to updates in the Material Specifications.
• Intermittent vs. Continuous Vent: The nature of the vent (intermittent or continuous) was questioned.
• Acoustic Measurement Distance: Clarification is needed on the distance from the silencer outlet at which the 85dBA noise level should be calculated.
• ASME Code Requirement: Regarding Note 3 (Max 120 psig inlet pressure), clarification was sought on whether the inlet needs to create and maintain 120 psig or simply be designed to 120 psig. The response confirms it should be designed to 120 PSIG.
• Diffuser ASME Code: For Note 8 (ASME Section VIII, Div. 1 code diffuser), clarification was sought on whether the diffuser needs to be built to or designed to the ASME code. The response states it should be designed to ASME Code Section VIII, Div 1.

Vendors need to consult the updated Material Specifications for answers to several key technical questions. Further clarification is required on the design flow rate, acoustic measurement distance, and the nature of the vent. The ASME code requirement for the inlet and diffuser has been clarified as 'designed to' rather than 'built to'.

Questions & Answers / Clarifications

This document provides responses and clarifications to vendor questions regarding the SPMYM326Q3113 Vent Silencer opportunity, as of Amendment 01 dated 3/10/2026.

• Flow Rate: Vendors inquired about the design flow rate, noting the specification mentioned "12,000 SCFM (or more)" and the potential for silencer failure if it handles significantly more flow than designed. The response indicates that updates to the Material Specifications address this.
• Pressure and Temperature: Questions were raised regarding the maximum air flow, and the pressure and temperature of the air upstream of the vent or control valve. Vendors requested this information for accurate quoting. The response directs vendors to the updates in the Material Specifications.
• Vent Type and Distance for Noise Measurement: Clarification was sought on whether the vent is intermittent or continuous, and at what distance from the silencer outlet the 85dBA noise level should be calculated (e.g., 3ft, 5ft, 20ft). The response refers to the Material Specifications for these details.

Vendors are advised to review the updated Material Specifications, which presumably contain the answers to their questions regarding flow rate, pressure, temperature, vent type, and noise measurement distance. These clarifications are crucial for preparing an accurate quote.
