Technical Description Principle of operation (FHM) Treated fresh air (from an air handling unit) or return air from the room is driven into a pressure chamber that is fitted with HEPA filters which are installed horizontally across the entire area of the pressurized field (fitted via clamps to a sealed stainless steel welded frame). After passing through the HEPA filters the cleaned air is pushed through outlets along individually arranged lighting to create a protection zone around a product or a patient. Afterwards, contaminated air is extracted from the room into a central air handling unit or supplied via the power module. The height of the FHM unit is 450 mm. The dimensions are determined according to the requirements of the facility system designer. A large-size unit is divided into sections which are supplied separately and connected together on site. The joints are designed to minimize their effect on the quality of laminar air flow and should be determined during the planning stage. 6 PR-2012-0057-GB Subject to changes R3-02/2017

Project Design Instruction Dimensions and tolerances Consider manufacturing and assembly tolerances when designing the dimensions of the FHM field (theoretical tolerance of 5 mm is recommended). The picture shows a sample unit connected to a suspended false ceiling (KS false ceiling profile) and R panel (the joint is covered by a R30-radius profile). joint The maximum size of the unit is limited by structural, manufacturing and transport options and is determined upon agreement between the manufacturer, designer and end user. Large-size fields include more components with emphasis placed on minimizing the effect of joints between different parts and ensuring uniform air flow (see the cross section). The casing is suspended on M8 threaded rods using suspension lugs located outside the unit (access to the outer sides of the unit must be provided). The rod is screwed into a riveting nut located on the suspension lug and secured by an M8 nut. To set a horizontal position we recommend using specially-provided anchors. The project designer determines the type of material used for anchoring the unit to the ceiling. For detailed instructions on mounting contact your relevant sales office. Space for valve assembly When designing FHM PowerU Cool and PowerS Cool units, ensure enough space for the valve assembly. Consult the manufacturer for the location of these components and the required piping. Several units (installed next to each other) can be supplied from a single valve assembly (each coil must have its own balancing valve). We recommend using special wall panels equipped with ducts for piping; the valve assembly can be mounted in a wall-panel compartment (access through an inspection door). Panel height If a partition wall is connected to FHM, such panels should not project more than 30 mm into the bottom edge of the laminar module (due to risk of damage by contacting piping or by-pass). NOTICE! Ordering code does not fully describe the unit. Technical assesment including schematic drawing, showing positions of soft walls, face panels, velocity sensors, atypical details etc. is an integral part of every price offer. 22 PR-2012-0057-GB Subject to changes R3-02/2017
Project Design Instruction Switch box When designing FHM and FHM PowerU units consider the required access to the switch box mounted on the unit side (e.g. provide an inspection tile in the false ceiling make sure to avoid contact with other lines, pipework and components).
