What Mass-Vac does

Mass-Vac (MassVac Inc.) is a US-based, privately-held specialty manufacturer and distributor founded in 1971 and headquartered in North Billerica, Massachusetts. The company operates with 101-250 employees and focuses exclusively on vacuum pump support products, positioning itself as the only supplier dedicated entirely to vacuum and exhaust traps associated with vacuum systems. Its proprietary portfolio centers on vacuum inlet traps (Multi-Trap, Posi-Trap, Visi-Trap product lines), oil mist eliminators with claimed 99.999% oil vapor removal efficiency, and vacuum degassing systems in chamber, 4-gallon, and 15-gallon configurations. The company also distributes complementary OEM products including NAVAC rotary vane pumps, Edwards gauging and leak detection equipment, Welch laboratory pumps, and Inland Vacuum fluids, creating a bundled vacuum support offering.

The business runs on a direct sales model with inside sales handling quotes and technical recommendations via phone (800-868-6700) and email ([email protected]), supplemented by a global network of authorized distributors covering 20+ countries. Customers are industrial, laboratory, semiconductor fab, and chemical/pharmaceutical operations using vacuum systems that require contamination protection and reliable pump performance. Mass-Vac emphasizes customized application engineering over catalog selling, leveraging 50+ years of accumulated process expertise. Revenue is generated primarily through one-time equipment sales with no disclosed pricing, no subscription or recurring software model, and an ancillary rebuild/certification service line that monetizes the installed base of vacuum pumps.

Mass-Vac is independently owned with no parent company, no external funding rounds, and no M&A activity identified in the available data. The company is actively expanding its distributed product portfolio (multiple 2024 OEM partnerships) and launched a new oil mist eliminator line in March 2026, while extending international reach through regional distributor partnerships. There is no evidence of AI/ML, software, or recurring revenue models; the business is fundamentally a specialty industrial hardware company.
