Unit series Fresh Heaven MAXX O / POWER
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
unit series:
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.
FHMO is not equipped with sound attenuating elements.

Operating principle
Air flow from the air-handling unit (1) is mixed with the recirculated air (2) from the
POWER module (3) in the mixing chamber (4) and discharged into the pressure cham-
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 (QEFresh Heaven MAXX O POWER Fresh Heaven MAXX O / POWER
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

Layout tips
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
Installation
The FHMO modules, mixing and recirculation modules are suspended on mounting
lugs using M8 threaded rods and special anchors.
• ensure to prepare M8 threaded rods in the concrete ceiling before suspension
• ensure access to outer sides of the unit
