Use and Importance of Hygienic Air Handling Units in Healthcare Facilities
Air quality and HVAC systems in healthcare facilities are critical for patient safety and infection control. Hygienic air handling units (AHUs) are specially designed to meet these needs.
What is a Hygienic Air Handling Unit?
Hygienic AHUs are systems developed according to the specific requirements of healthcare facilities, providing high-efficiency filtration and controlled airflow. Key features include:
-
Antimicrobial surface coatings
-
Leak-proof construction
-
Easy-to-clean design
-
High-efficiency HEPA filtration systems
-
Condensate control mechanisms
Application Areas
-
Operating rooms
-
Intensive care units (ICUs)
-
Sterile pharmaceutical production areas
-
Neonatal units
-
Oncology and immunodeficiency clinics
-
Microbiology laboratories
