Procurement Summary

Supply of one (1) each dust aerosol generator with capability of an output range of 0.5 to 160 g/m3, a particle size range capable of less than 0.5 µm, constant supply of powders, ability to change the speed of the feed chain, ability to test different dust types, and is refillable during operation. This equipment is used to establish a well-controlled, respirable dust atmosphere inside the test chamber. Researchers introduce aerosol using a dust aerosol generator. This approach provides fine control as well as an extremely stable operating state for extended testing.

Waiver Rationale Summary

Market research was conducted via online searches through various sites. This included a thorough search of GSA vendors, as well as a general web search to determine if any other companies could supply the correct piece of equipment needed for controlled environmental dust particle testing. Due to the need to replace an outdated dust aerosol generator with a similar piece of equipment, TSI Inc. with its TSI 3410L was determined as the only capable produce satisfying the minimum technical requirements with particle size range as low as 0.2 µm and the output concentration range of 0.5 - 16 g/m3 while also maintaining compatibility with the existing test lab equipment. Additional market research did not show any other companies that could provide the needed piece of equipment.
