DIF-OT Ceiling filter

DIF-OT is a ceiling filter system for operating theatres requiring an ISO5 Clean Room Classification, suitable for transplants, heart surgery, ortho-paedics and neurosurgery.

The system provides differential airflow velocities from the centre towards the perimeter of the treated zone, ensuring a constant and efficient purging of the surgery area. The laminar airflow diffusion eliminates induction and prevents contaminated air from entering the operating area, without the use of potentially restrictive guide curtains.

Functions

• Differential flow velocities
• ISO5 classification
• No induction
• Low velocity

Product Facts

• Stainless steel AISI 304 frame
• HEPA filters H14
• Filters with integrated equalizer (synthetic cloth)
• Reverse liquid seal

Construction and function

The DIF-OT unidirectional ceiling filter system produces a controlled distribution of the filtered air via the absolute filters above the operating area. The air diffusers are integrated with absolute HEPA filters to obtain a unidirectional air flow above the area occupied by the surgical team.

The system creates differentiated air flow velocities, with the highest speeds being generated in the centre of the treated zone, thus ensuring a constant and effective purging of the operating area.

An integrated filter equalizer maintains the necessary air uniformity, even at low speeds.

DIF-OT filters are available in different sizes, in an air flow range from 5000 to 9500m3/h, in order to satisfy the requirements of all standard operating room environments.

The DIF-OT ceiling filter system is designed for use in critical operating rooms used for transplants, heart surgery, orthopaedics and neurosurgery. The low speed and total absence of induction also provides a comfortable environment for the operating team. Furthermore, thanks to the features indicated in the previous chapter, the DIF-OT allows for significant energy saving levels.

It is advisable that the OT lamp is positioned outside the system. Should this not be possible, a sealed panel suitable for a lamp installation replaces one of the filters.

  Hospital ventilationFor a healthcare facility to operate at its maximum potential, it has to have all systems working at the optimum. This not only applies to staff, communications and life support systems, but also to pipe work, cleaning and ventilation systems.
