About this file
This is a sole source agreement letter and supporting patent documentation from Airvac, Inc. to Sarasota County, Florida, for the provision of Airvac vacuum sewer system products and services. Airvac, Inc., headquartered in Rochester, Indiana, is proposing to be the sole source supplier for vacuum sewer technology products used in the county's vacuum sewer system. The letter, dated January 27, 2026, establishes Airvac's proprietary position in the market and clarifies that the Airvac system is a fully integrated and interdependent system protected by multiple United States patents, pending patent applications, trademarks, copyrights, and trade secrets. The agreement emphasizes that only products manufactured, supplied, and expressly authorized in writing by Airvac, Inc., and used in strict accordance with Airvac specifications constitute an authorized Airvac system. Sarasota County reserves the right to cancel the sole source procurement and advertise a competitive solicitation if respondents demonstrate the ability to supply the same or substantially similar products and services.
The supporting documentation includes a comprehensive worldwide patent listing prepared by Barnes & Thornburg as of February 12, 2025, detailing Airvac's intellectual property portfolio across multiple countries and patent categories related to vacuum sewage system controllers, monitoring systems, variable speed pumps, sump breather apparatus, wireless alarms, and pipe couplings. Patents are issued or pending in jurisdictions including Australia, Canada, the European Patent Convention nations, Brazil, and the United States, with expiration dates ranging from 2026 to 2042. The documentation also includes a trademark registration for "Discover Better" in the United States. The filing underscores Airvac's extensive intellectual property protections and the rationale for sole source procurement, as use of non-Airvac products or subsystems may infringe intellectual property rights, void warranties, and transfer all responsibility and liability for system performance and compliance to the system owner, designer, and installer.

RE : Airvac Sole Source Agreement 2026
Airvac’s vacuum sewer technology is a proprietary, integrated system protected by multiple United States patents, pending patent applications, trademarks, copyrights, and trade secrets, covering the system’s architecture, operating principles, control methodologies, software, firmware, hardware, and the interaction of all system subsystems.
The Airvac system is not a collection of independent components. Rather, it is a fully integrated and interdependent system, in which performance, reliability, and longevity depend on the coordinated operation of proprietary control logic, sequencing, modulation, monitoring, and interface mechanisms developed and owned exclusively by Airvac, Inc.
Any product, component, software, firmware, control logic, subsystem or system training represented as “equal,” “compatible,” “interchangeable,” or “functionally equivalent” to any portion of the Airvac system is not authorized, not equivalent, and not approved by Airvac, Inc., regardless of claimed similarity or intended function.
Use of non-Airvac products or subsystems within an Airvac system, including partial substitutions or hybrid configurations, may infringe Airvac intellectual property rights, voids all Airvac warranties, and transfers all responsibility and liability for system performance, reliability, regulatory compliance, and long-term operation to the system owner, designer, and installer.
Only products manufactured, supplied, and expressly authorized in writing by Airvac, Inc., and used in strict accordance with Airvac specifications, constitute an authorized Airvac system.
Respectfully, Clint Hawn Chief Executive Officer
