UCV HEPA perforated SS diffuser

From design to completion infection control is our commitment

Air filtration and distribution system for operating theatres

UCV TAS-OP system is composed of a plenum, a filter housing frame and micro-perforated panels, available in AISI 304 stainless steel as the TAS-OP version (AISI 316 on request) and in painted steel as the TAS-FV version.

Advantages

• Cost-effective.

• wide range of sizes.

• Perfectly planar to make cleaning operations easier.

• Resistance to sanitation and cleaning operations.

• HEPA filters produced, tested and packaged individually in a cleanroom.

• Perforated plate diffuser panels easy to disassemble in order to quickly and simply access the filters.

Designing an operating theatre just got easier!

TechIN is excited to introduce the REVIT families of our exclusive partner SagiCofim.

Watch the video and get to know how in only 6 minutes you can integrate our supply and exhaust systems solutions to your project.

Supply Systems

• Unidirectional flow OR canopies (OR unidirectional flow)

Exhaust Systems

• Exhaust grilles and airflow dimensioning

The system is composed of a plenum, a filter housing frame and micro-perforated panels, available in AISI 304 stainless steel as the TAS-OP version (AISI 316 on request) and in painted steel as the TAS-FV version.

To ensure the proper, uniform flow distribution, the plenum has one or more air inlets, which are sized depending on the air flow rate and the spaces available.

The filter housing frame is perfectly flat and designed to guarantee the seal with the filters, which can be mechanical (with seal on the filter) or liquid (with gel on the filter).

The installation and fixation procedure for the filters has been carefully designed to guarantee the complete airtightness of the system and to be simple and convenient using special locking elements.

The micro-perforated diffusers, properly designed with the correct empty/full percentages, ensure uniform distribution of the air into the environment in accordance with the regulations for that health sector.Depending on the size of the ceiling, it can be supplied in one or more parts (for in-situ assembly).

The system uses DELTA absolute filters, with 99.995% MPPS and H14 efficiency, in accordance with UNI standard EN 1822-2009.

Each individual filter is made using mini-pleat technology, with an aluminium frame, aluminium protection grid painted on both sides, and, to ensure complete tightness of fit, can be supplied with a continuous semirounded polyurethane seal or, for liquid seals, with a polyurethane based gel.

Each individual filter is efficiency tested by an optical particle counter (OPC), in accordance with EN 1822-4.

Testing and packaging are done under unidirectional airflow in ISO 5 classified Cleanrooms, during which the filters’ individual test reports are issued and inserted into the packaging.

To make all tests and validation procedures as simple as possible, the TAS-OP systems is supplied with sampling points.

Leak test: to verify that the system installation complies with regulations, an initial leak test must be performed. This is to check that no leaks have been caused due to any installation errors or improper handling of the filters.

Room validation: only once the leak test has been performed and the room properly cleaned, can the Operating Theatre then be validated in accordance with the required ISO classification.

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

• Medical equipment

• Time duration of the surgery

• Among others…

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 dimensions

• Different duct connections (individual, double, top connection…)
