Ultra Clean Ventilation
Exceptional air quality, pure and simple
Since 1962, the Howorth EXFLOW™ UCV system has set the standard for Ultra Clean Ventilation systems.
It has been installed in over 4,500 operating theatres worldwide, transforming post-procedure recovery.
By creating an Ultra Clean Air zone around the patient and surgical team, the wound site is protected from Surgical Site Infections (SSI).
And today, our ventilation innovation goes on and on.
Ultra Clean Ventilation
The use of Howorth’s EXFLOW™ UCV has been proven to continuously reduce the occurrence of SSI's in Operating Rooms.
Installed in operating rooms worldwide, the Howorth EXFLOW™ UCV canopy is available in two sizes, EXFLOW™ 28 (2.8m) and EXFLOW™ 32 (3.2m).
Both models provide microbiological cleanliness and airflow results exceeding all current regulatory requirements.
The EXFLOW™ Evolution screenless UCV canopy incorporates a patented Coanda air containment system to maximise the clean area and minimise the risk of contamination in the clean zone without the need for side screens, low-level vents or mechanical extract.
- Unique Exponential airflow pattern
- No Entrainment, even without full side walls
- Up to 500 air changes an hour
- Larger clean zone protects instruments
- Graded air flow, higher central velocity overcomes thermal plumes
- Completely self-contained
- No need for any secondary recirculation ductwork
