The US Coast Guard Training Center Petaluma is competitively soliciting a purchase order restricted to the Kaeser Rotary Blower Model EB421 C, citing critical integration constraints at its existing wastewater treatment facility. Only authorized Kaeser distributors may submit quotations; offers proposing alternative manufacturers or non-interchangeable equivalents will not be considered. Award will be made on the basis of the lowest-priced, technically acceptable quote from an authorized distributor. The requirement is not a sole-source award, and the detailed brand-name specification is attached to the notice. Performance will occur at the US Coast Guard Training Center Petaluma.
