Pneumatic Tube System Service

Hospitals send 10,000 blood samples a day through tubes in the walls. When a tube system fails, the hospital pays whatever it takes.

Pneumatic tube systems move physical objects — blood samples, medications, documents, cash — through sealed tubes using compressed air or vacuum. Hospitals are the dominant customer, with virtually every US hospital over 100 beds operating a pneumatic tube network connecting nursing stations, labs, pharmacies, and operating rooms. A typical 300-bed hospital runs 50–150 stations and processes 3,000–10,000 carrier deliveries per day. Banks, large pharmacies, drive-thru restaurants, and nuclear facilities also operate pneumatic systems. Service work — preventive maintenance contracts, carrier replacement, blower repair, and station retrofits — is dominated by two manufacturers (Swisslog and Pevco) and a small network of independent service contractors. A 3–5 technician shop holding service contracts on 8–20 hospitals generates $700K–$2.5M annually with 35–45% net margins. The work is utterly recession-proof: hospitals legally cannot operate without functional tube systems for medication delivery, and emergency repair calls bill at $250–$450/hour with travel premiums. New system installations run $400K–$2M per hospital and are typically subcontracted by general contractors during hospital renovations.
