About this file
This document is a Statement of Work (SOW) for the Human Landing System (HLS) Plume Surface Interaction Ground Test project, which requires the installation of HEPA filters into six different locations inside the 60ft Vacuum Sphere Facility at the Langley Research Center.
The contractor shall produce 34 HEPA filters that are 99.97% efficient at 0.3 microns and rated for 2000 CFM, with stainless steel frames and vacuum-approved silicone gaskets. The contractor shall also produce 8 custom filter frame assemblies for the sphere's diffusion pumps, in-bleed and vent adapters, lid, raised floor, and main intake. The contractor shall collaborate with the Langley test team to ensure accurate measurements, bolt patterns, placements, and fit of the components. The period of performance requires the contractor to design, develop, and deliver the required materials by August 2024.
The related federal contract opportunity is a sole source procurement for the 60ft Sphere HEPA Filters, which NASA intends to award to FILTRA-SYSTEMS COMPANY, LLC under the authority of FAR 13.106-1(b)(1)(i). The NAICS code for this procurement is 333998. Interested organizations may submit their capabilities and qualifications to the identified point of contact by 5/8/2024, after which the government will determine whether to conduct a competitive procurement.

STATEMENT OF WORK
1. Objective/Requirements Human Landing System (HLS) Plume Surface Interaction Ground Test project requires HEPA filter installation into six different locations inside the 60ft Vacuum Sphere Facility. The HEPA filters are intended to protect the facility vacuum system from the entry of particulate matter during a test with lunar simulant ejecta inside the sphere at vacuum. Proposal/Bid will be chosen based on technical acceptance and past performance.
2. Characteristics, Scope, and Specs
The contractor shall perform the following duties:
Produce HEPA filters according to the following specifications:
o 99.97% @ 0.3 micron HEPA filters rated for 2000 CFM each o Frame constructed from 304 stainless steel o Outside dimensions of 23.375” x 23.375” x 11.5” o 1.4” Vacuum approved silicone gaskets shall be included for each to seal filter to the frame assembly o Can withstand a vacuum of .7 TORR o Potted internally with a 2-part polyurethane sealant
Produce filter frame assemblies for:
o Sphere Diffusion Pumps x (4)
3/8” aluminum alloy custom adaptor plate with multi-bolt pattern to match the mounting locations
Custom captive swing bolt style clamping system to seal filter to frame Frame is constructed from aluminum to reduce corrosion o In-bleed and Vent Adapters x (2) 36” diameter, custom circular cover with pull-down bracketry to seal with radius interior floor Constructed from aluminum to reduce corrosion Custom captive swing bolt style clamping system to seal filter to frame o Lid x (1) Keeping all filters consistent, the Regolith bin lid will utilize the same filter Constructed from aluminum to reduce corrosion Custom captive swing bolt style clamping system to seal filter to frame o Raised Floor x (1) Keeping all filters consistent, the Regolith bin lid will utilize the same filter Constructed from aluminum to reduce corrosion Custom captive swing bolt style clamping system to seal filter to frame o Sphere Main Intake x (1) Constructed from aluminum to reduce corrosion Custom captive swing bolt style clamping system to seal filter to frame o Vendor shall collaborate with LaRC test team to ensure measurements, bolt patterns, placements, and fit are accurate and technically acceptable.
On-site collaboration may be suggested
