UCV HEPA differential velocities
Unidirectional airflow with decreasing air velocity from the centre
Aseptic for the patient, Safe for the medical staff, Comfort for the surgical team
DIF-OT is a ceiling-mounted HEPA filter system for Ultra Clean Ventilation (UCV) specifically designed for operating theatres to meet the highest cleanness during critical surgery like orthopedics, heart surgery, transplants and neurosurgery.
The groundbreaking system provides differential velocities decreasing from the centre towards the perimeter of the active surface, ensuring a constant and effective purging of the surgery area.
Self-balanced differential airflow velocities.
No air induction.
Effective ultra-clean central airflow to protect the patient from airborne particles.
Draft-free airflow velocities around the surgical table.
Utmost flexibility in positioning light stem and suspended equipment.
The ultimate solution for hybrid operating rooms.
The highest airflow uniformity thanks to the downstream equalizer.
Colour code filters for correct filter installation.

Low noise level.
Structure in stainless steel for maximum resistance to sterilizing agents.
System designed for use in total safety without need for perimeter rigid curtains.
ISO Class 5 Operational.
The best choice for new projects and for retrofit.
Modular design: it can be integrated into different size environments.
The absence of barriers and side curtains facilitate the equipment handling in the room.
The last filtration system must be able to remove every type of pollutant, as quickly and efficiently as possible. Considering that it is almost impossible to eliminate the sources that generate and release biologically active particles, since the main sources of contamination are the same people who work in the operating room.
This is the main reason SagiCofim has designed and built a unique and unconventional solution to allow the engineers to reach the highest level of excellence in the indoor air quality, even in the most critical surgery rooms. This solution is called DIF.OT.
The 3 different air velocities work in synergy in order to ensure a clean air flow directed from the zone occupied by the surgical table towards the perimeter areas of the operating room to ensure maximum patient protection.
The clean air from the centre effectively protects the patients.
In the area where the staff is working the air velocity is low enough to avoid discomfort.
The lowest velocity avoids any risk of contaminated air induction from the room to the clean area.
The different air velocities are guaranteed by a filter section integrated by tested HEPA filters.
Using specifically controlled permeable air diffusers, the 3-velocities system guarantees the highest levels of efficiency.
These membrane diffusers ensure maximum uniformity of the downstream air flow of each filter, consequently, allowing to have three different zones with three well-defined velocities.
Such uniform flow can not be achieved with conventional terminals for air distribution often used in similar applications.
The installation and the correct positioning of the different filters with the integrated diffusers are guided by the filter colouring, avoiding mistakes during installation on the field.
There are several factors and considerations to be studied to define the appropriate dimensions of the HEPA UCV diffuser, some of them:
Type of surgery
Number of medical personnel during surgery
Time duration of the surgery
Meanwhile, the correct dimensions shall be defined by the actual dimensions of the protected zone to establish once the correct airflow and velocities are set. SagiCofim offers standard UCV diffuser dimensions to be considered (See table on the image on the right).
If your project requires custom made solutions, our team will develop special equipment like:
Different duct connections (individual, double, top connection…)
Our team is looking forward to working with your project!
