Fresh Heaven MAXX O LAMINAR AIRFLOW UNIT

The Fresh Heaven MAXX O laminar ​air-flow units are part of the structural arrangement of the suspended ceiling of an operating theater.

Fresh Heaven MAXX O unit supplies clean air in a low-turbulent and vertical flow into an operating room. Thus, the contamination of sensitive areas and equipment can be held at a minimized level.

AHU supplies pre-treated air through rectangular inlets into the pressure chamber with filters. Clean air flows out of a laminarizer stretched across an aluminum frame into the operating theater, forming the protection zone. Contaminated air is extracted via extract-air grilles into AHU.

Fresh Heaven MAXX O unit design provides space in the center for surgical lighting installation. The laminarizer’s circumference is lit by LED lighting integrated into the casing’s sides. To enhance laminar airflow and minimize air turbulence, a PET-G soft wall can be integrated around the entire circumference of the unit.

There are available 8 sizes, and an air volume is given at a velocity of 0.30 m/s:

• A – 320 x 320 x 45 cm, air volume 11 060 m³/h
• B – 300 x 300 x 45 cm, air volume 9 720 m³/h
• C – 300 x 240 x 45 cm, air volume 7 780 m³/h
• D – 300 x 200 x 45 cm, air volume 6 480 m³/h
• E – 240 x 240 x 45 cm, air volume 6 220 m³/h
• F – 240 x 180 x 45 cm, air volume 4 670 m³/h
• Y – 183 x 180 x 45 cm, air volume 3 560 m³/h (without a central passage for an operating lamp)
• Z – 183 x 123 x 45 cm, air volume 2 430 m³/h (without a central passage for an operating lamp)

Filters offer includes HEPA filters in an aluminum frame 104 mm high. The filter features a gel gasket and protective grid on its clean air side. The filters are available in following filtration classes:

• H13
• H14

Casing:

• Varnished steel RAL 9010
• Stainless steel V2A ~AISI304

Outlets:

• Single-layer PES (polyester) fabric
• Double-layer with differential airflow (higher air velocity in the central area, measuring 100 x 200 cm)
• Perforated steel painted RAL 9010
• Perforated stainless steel, electropolished

Selectable accessories:

• Differential-pressure switch – monitors differential pressure of filters (pressure connection via two plastic tubes), can be equipped with connections to a filter-exchange indicator
• Filter-exchange indicator – may be installed in the central passage of the low-turbulence flow unit to signal filter clogging via red LED
• Lighting- LED lighting can be installed around the entire perimeter of the laminar air-flow field
• Border soft wall as PET-G screen – to minimize air turbulences, maximize laminar air-flow zone and prevent reduction in its cross-section – a soft wall (curtain) can be integrated on the entire circumference of the unit. Standard width 30 cm.
