Hospitals & Clinics — HEPA H14 Air for Infection-Sensitive Spaces
Pathogens as small as 0.1 µm linger in hospital air. Standard building HVAC isn't engineered to catch them. The TROTEC TAC line is.
The challenge
Healthcare-associated infections (HAIs) are among the most studied airborne risks in modern medicine. Bacteria, fungal spores and aerosolised viruses routinely measure between 0.1 and 1 µm — small enough to pass through the F7- and F9-grade filters that most building HVAC systems rely on. For immunocompromised patients, transplant recipients, neonates and post-surgical wards, that filtration gap is clinically dangerous.
The result is a paradox: the spaces that need the cleanest air — operating theatres, isolation rooms, oncology wards — often run on ventilation designed for thermal comfort, not infection control.
What TROTEC TAC adds
Each TAC unit pairs a genuine HEPA H14 filter (99.995 % separation at 0.1 µm, certified to EN 1822) with airflow rates from 750 to 5,700 m³/h — enough to deliver 6–12 additional air changes per hour on top of existing HVAC. Units are mobile, redeployable between wards in minutes, and ship with serial-numbered factory test certificates for compliance documentation.
Independent clinical-room efficacy
Independent testing by HYBETA GmbH (Germany) per VDI-EE 4300 Sheet 14 on the TAC V+ / TAC M line shows full compliance with the engineering benchmark for mobile HEPA purifiers in shared rooms:
- 128 m³ room (typical large meeting / patient room) — 5.9–7× air changes per hour, with 90 % particle reduction reached in under 30 minutes for 0.3 µm and finer particles.
- 267 m³ room (large staff break-room scale) — 5.2× ACH delivered at Stage 6, with measured airflow exceeding the manufacturer specification on every fan stage.
HEPA H14 leak tests on every shipped filter pass to ISO 14644-3 cleanroom integrity standards. Full reports available on the Downloads page.
Typical healthcare configurations
- Operating theatres — supplemental sterile-grade air above the surgical field.
- Isolation rooms — negative-pressure setup with HEPA-filtered exhaust.
- Oncology and transplant wards — positive-pressure sterile zones.
- Waiting rooms and A&E — high-occupancy zones with elevated background pathogen load.
Trusted in healthcare across Europe
TROTEC TAC technology is in service at many of Europe's leading healthcare and pharmaceutical institutions, including Charité Berlin, Klosterfrau Healthcare Group, Caritas, Malteser, Dräger, Grünenthal, Merck, the Paul-Ehrlich-Institut, Eurofins Genomics and the Deutsches Rotes Kreuz.
