Wall-mounted air purifier COMBI 2.3

for healthcare facilitiespositive pressure

Overview
The COMBI 2.3 is an air handling unit engineered for continuous, intensive use in operating theatres, intensive-care and other critical hospital zones. It provides validated HEPA filtration, stable temperature and humidity control, and maintains controlled positive pressure (PPD) to support ISO-class air quality requirements.

Key features

• Dual-stage filtration: pre-filter plus validated HEPA module for particle removal
• Integrated cooling and heating via thermodynamic coils for thermal stability
• Adjustable EC fans enabling precise airflow regulation
• Continuous pressure monitoring with alarm system for reliable PPD control
• Low-noise, energy-efficient operation suitable for clinical environments
• Stainless-steel modular frame and internal layout for fast service access

Design and control
Pressure sensors, thermodynamic coils and an intelligent control software maintain uniform environmental conditions. Automatic calibration routines simplify restart after maintenance. The modular internal design allows rapid replacement of filtration and mechanical modules.

Performance & validation
Designed as the core configuration of the COMBI Series for surgical and critical-care applications. Independent testing (e.g., VITO, KU Leuven) verifies filtration efficiency and real-world contribution to indoor air quality. Meets ISO 14644 performance expectations when installed and validated in situ.

Typical applications

• Operating rooms
• Isolation rooms
• Intensive care units
• Procedural suites and other high-demand hospital zones

Documentation
Model brochure, validation reports and independent efficiency studies are available in PDF format for specification and compliance review.
