RFP Title
Innovative Air and Space Cleaning Technology
RFP Description

NineSigma, representing a multibillion-dollar global manufacturer, seeks innovative air and space cleaning technologies instead of the conventional filter dust collection and electric dust collection technologies.



Recent increase in interest of health demand leads to increase in demand for air quality year by year.


Based on this requirement, our client, a global manufacturer, is developing more highly efficient air and space purification technologies than ever before, which is still limited to the technology framework of traditional filter dust collection and electric dust collection.


Therefore, the client has issued this open request in order to specify an innovative technological approach as soon as possible that enables higher air and space purification than conventional technologies, and bring products to the market at an early date.


Key Success Criteria

Requirements for air purification technology with a final aim of practical use

  • At the processing flow rate of 3400 m3/hr, the following conditions shall be satisfied;
    • Capture efficiency: 90% or more of particles with a size of 0.4 μm can be removed
    • Pressure drop: 100 Pa or less
    • ASHRAE Dust holding capacity (load dust for air filter specified in USA ASHRAE standard: ASHRAE 52.2 and European EN standard: EN 779): 650 g or more (Final pressure drop 450 Pa)
  • Size of dust collector: 610 mm × 610 mm × 290 mm or less
  • In addition to the dust collection capability described above, a technology that allows for satisfying the following points is preferable.
    • Has an excellent continuous usability and requires the least frequency of maintenance
    • Comprises a system to measure the degree of contamination of air quality in spaces to be purified and autonomously controls the purification performance according to the measured degree (for example, lower performance when the air is clean)


Considering the higher requirements described above, we welcome proposals if the technology of interest can be achieved with additional development of about two to three years, even if it does not meet the requirements at the present time.


Possible Approaches

Possible approaches

Anticipated project phases or project plan

Respondents should submit proposals using the attached Response Template.


The client will review submitted proposals and possibly ask clarifying questions before selecting the most suitable candidates for collaboration. The client will select the best candidate(s) through evaluations. During the selection process, the client may execute non-disclosure agreements (NDA) with selected respondent(s), seek further information disclosure, and discuss specific development targets or potential opportunities.

The client will execute necessary agreement(s) with the selected respondent(s) and move to the advanced development phase. Specifics of any collaboration will be determined through consultation with the concerned parties.


Preferred Collaboration types
  • Joint Development
  • Contract Research
  • Technology Licensing
  • Supply Agreement
