The requirement is brand name mandatory to Howden North America for a fan and controller due to their unique replacement configuration, so quotes for other manufacturers will not be considered.

Offerors must be registered in SAM, complete specific provisions, and submit quotes via email. No budget amount is specified in this notice.
