Fresh Heaven MAXX O application field

                            The Fresh Heaven MAXX O series comprises low-turbulence flow units for pressurized
                            fields in operating theaters. The purpose of units is to prevent contamination of
                            operating zone through airborne particles by creating a protective zone of fully filtered
                            air around the patient.
                            Fresh Heaven MAXX O units control levels of contamination and safeguard full and
                            unidirectional air filtration across the entire outlet surface.
                            Low-turbulence flow units are intended for operating theaters with the highest require-
                            ments for uniform vertical air flow in hospitals complying with the local requirements
                            and standards.

Fresh Heaven MAXX O model range
                            Individual components are selected in the layout stage and meet customized require-
                            ments on site. Units are designed according to the requirements of DIN 1946-4 for
                            rooms of Class Ia.
                            For delivery - large-size units are divided into sections which are supplied separately
                            and connected together on site. Fresh Heaven MAXX O unit range in presented by two

     Fresh Heaven MAXX O
                            Supply air is delivered by a central-plant air handling unit into the pressure chamber
                            and then filtered and delivered into the operating area.

     Fresh Heaven MAXX O
                  POWER
                            This unit design is based on the Fresh Heaven MAXX O version and is equipped with
                            a recirculating POWER module which sucks air within a room. Recirculated air from
                            the POWER module can be mixed with outside air supplied from central plant air-hand-
                            ling unit in the mixing chamber. This air flow is then delivered into the pressure cham-
                            ber, filtered and diffused into the operating area.

Operating principle
                                  A central-plant air handling unit (1) supplies primary pre-treated air through rectangular
                                  air inlets (2). Pre-treated air is discharged into the pressure chamber (3) above a set
                                  of filters (4). The filters are fixed via clamps to a welded frame. Clean air, after filtering,
                                  flows out of a single or double-layer laminarizer (5) stretched across an aluminium
                                  frame into the operating theater (6) and forms the protection zone. Double-layer lami-
                                  narizer makes it possible to create differential air flow with a higher air speed within the
                                  area of surgical lighting.
                                  Contaminated air is then extracted from the room via extract-air grilles (7) into a central
                                  air handling unit (1). The unit design of Fresh Heaven MAXX O provides a space (8) in
                                  the centre to enable installation of surgical lighting.
                                  The circumference of the laminarizer is lit from above by LED lighting integrated into
                                  the sides of the casing. A PET-G soft wall (9) with an optional media bridge for supply
                                  connections may be installed around the unit.

Unit sizes, variants and air flow range
                                     The Fresh Heaven MAXX O series comprise 8 unit sizes.
               Modular setup         Unit sizes A to F are combined of modules M1 and M2. These unit models comprise
                                     two M1 and two M2 modules. Unit sizes Y and Z can only include M1 module.
                                     Sample modular setup of Fresh Heaven MAXX O and overall unit sizes are presented
                                     as follows. Also refer to Fig. 4 for individual sizes and filter setup.
                     Air volume      Different air volumes are specified at three average air velocities of 0.24, 0.30 and 0.38
                                     m/s. Air volume is specified on the basis of the overall unit surface calculated by mul-
                                     tiplying unit nominal length by width.

                                                                       Module          Module      Inlet                           Weight

Air-supply connections
                                    The unit can be equipped with a maximum of 4 air-supply connections, which are
                                    located on the vertical panels of the casing. These connections are used for air ducts
                                    from the central-plant air-handling system.

Rigid connection
                                    As standard units are equipped with rigid connections. All dimensions are specified in
                                    mm.

Operating principle
                                     Air flow from the air-handling unit (1) is mixed with the recirculated air (2) from the

                                     ber (5) above a set of filters (6).
                                     After passing through full-area HEPA (H13/H14) filters (6) air creates a low-turbulent
                                     displacement flow. The filters are fixed via clamps to a welded frame. Clean air, after
                                     filtering, flows out of a single or double-layer laminarizer (7) stretched across an alumi-
                                     nium frame into the operating theater (8) and forms the protection zone. This area
                                     encompasses the operating and sterile instrument tables. Double-layer laminarizer
                                     makes it possible to create differential air flow with a higher air speed within the area
                                     of surgical lighting.
                                     Smaller portion of polluted air is then extracted from the room via extract-air grilles (9)
                                     into a central air handling unit.

Distribution of air flow
                                     A central-plant air handling unit (1) supplies QF which is between 20-30% of the total
                                     air volume. The required outside air flow rate is primarily determined by internal loads
                                     and its minimum can depend on country regulations. Supply air is pre-treated in a cen-
                                     tral air-handling unit, which is located outside an operating theater, and delivered to the
                                     mixing chamber (4) of FHMO.Px units. There the supply air is mixed with pre-filtered
                                     (F7) recirculated air portion QR, extracted from the operating theatre. FHMO.P units
                                     are also equipped with flaps to avoid backflow through pre-filters in case of fan and
                                     power failure. Part of the polluted air flow is then extracted and directed to the air-han-
                                     dling unit (QE

                   QR regardless of clogging of filters with consideration of residual static pressure of
                   fans. To ensure the correct ratio and air-output velocity each outside-air duct must be
                   equipped with constant airflow regulators, which is not part of FHMO.P delivery.
                   The mixing ratio is preset to a constant value. To change the ratio the operator needs
                   to change air volume QF of AHU, recirculated air volume QR at the fans of FHMO.P
                   and the settings of air flow controllers (CAV) on inlet air ducts. The operator must
                   ensure that the total air volume Q100 remains unchanged.

Unit variants
                   The unit variants are performed as:
                   – Ceiling version where air intake for recirculating puproses is performed on the
                     ceiling level or in upper or lower wall corners
                   – Tower version where air intake for recirculating puproses is performed on the floor
                     level through rectangular vertical sections which are either installed in or outside the
                     operating theater

Delivery

                                    Fresh Heaven MAXX O components are packed in wooden/OSB crates and
                                    cardboard boxes. Quantity and dimensions are provided on request. Laminarizer,
                                    filter inserts and joining material are supplied is a separate packing.

Transportation
                                    Unit may only be transported in its original packing. A fork lifter is used to lift the unit
                                    components on a pallet and maneuver on site. If the site-installation space is limited, a
                                    ladder is used and unit components are moved manually.

Dimensions and tolerances
                                    The size of the unit is limited by structural, manufacturing and transport options and is
                                    determined upon agreement between the manufacturer, designer and end user.
                                    • Consider manufacturing and assembly tolerances when designing the dimensions of
                                        the FHMO unit
                                    •   We recommend to keep a tolerance of 5 mm
