Filter Fan Unit SILENT

Technical Concept

Product Description Filter Fan Units (FFUs) from M+W Products are designed to provide clean air to individual workstations or entire cleanrooms. Due to the symmetric construction of the noise absorbing internal flow fixtures, the filter downstream air velocity becomes very consistent and the sound power level is very low.

Depending on the configuration of the filter coverage and of filter classes, cleanroom classes ISO 1.0 to ISO 8.0 according DIN EN ISO 14644-1 can be reached. This brochure provides information about the device design – FFU SILENT AC with alternating current motor – FFU SILENT EC with EC-motor and advanced control and monitoring possibility

The FFU SILENT is in particular suitable for applications in unidirectional (laminar) airflow cleanroom areas with advanced requirements regarding downstream air velocity uniformity and noise level.

The product is protected by patent.

The unit consists essentially of the housing 1, the HEPA filter cell 2 and the compact fan unit 3 with impeller and motor 4 with inlet nozzle 5. The integrated baffle plate 1 a optimizes the uniformity of airflow towards the filter. The sound absorber 9 reduces the fan noise level.

– prefilter 11 for coarse particle filtration – AMC-filter 12 for filtration of gaseous contaminants – Cooling coil / heating coil 13 – Aerosol inlet connector, Aerosol measurement connector – air diffuser (perforated plate diffuser, swirl outlet) 10 The FFUs generate an uni-directional air-flow. If necessary filter cell classes H13 to U17 can be used. With implementation of the air diffuser 10 a turbulent airflow inside the cleanroom is created. The FFU fans have sufficient reserve capacity to overcome any additional pressure loss due to e.g. raised floor, return air ducts, prefilter or cooling / heating coils. The FFU SILENT AC is driven by a special developed single phase external rotor AC motor with internally wired thermal contacts for overload protection. The FFU SILENT EC is driven by an electronically commutated external rotor motor.

Device Installation

Dimensions

The installation into the M+W Products ceiling grid system → Ultraflex Grid Ceiling is very simple. The installation can take place from the cleanroom, using the ceiling grid system UFR-55/70-T 14 a with bearing rails 6 (Fig. 1.2). FFU and filter cell are installable independently from each other from the cleanroom side. Depending on the requirements on air tightness of the ceiling grid system, grid profiles without a gasket 14 a or grid profiles with fluid seal are available 14 c (Fig. 2.2). The sealing between the housing and the filter cell frame is done with a dry sealant 2 b (Fig. 1.2, 2.1 and 2.2).

Key Features

FFU SILENT AC

– FFU suitable for highest cleanroom classes and advanced requirements regarding downstream air-flow uniformity and noise level, in particular suited for applications in uni-directional (laminar) airflow cleanroom areas.

The units can be operated with the M+W Products → Control System AC individually as well as in groups. The setting of the desired volume flow takes place through a phase angle control device.

FFU SILENT EC Based on LON (Local Operating Network) the FFUs are merged to a network system through a special bus-system → Control System DC. This enables a simple and individual speed adjustment and monitoring of each unit, even in complex systems with several thousand units.

– FFU sizes fit in ceiling grid size 1 200 mm × 1200 mm 1 200 mm × 900 mm 1 200 mm × 600 mm – Low power consumption, very low sound pressure level – Easy operation, low maintenance effort – Applicable for individual workstations or entire cleanroom facilities

Power Supply

– Aluminum housing (standard), optionally steel powdercoated (disinfectant proof, color similar RAL 9010), different designs on request

A plug & play cable system is provided for the power supply. Each unit is connected through the existing terminal box 8, minimizing installation efforts.

– Filter cell classes H13 to U17 (standard H14) – Installed radial fan: Motor with internally wired thermal contacts – FFU SILENT AC with single-phase external rotor motor, volume flow adjustable through → Control System AC – FFU SILENT EC with electronically commutating external rotor motor, volume flow adjustable through → Control System DC – Minimized power supply installation effort due to plug & play cable system – Easy device installation from below (cleanroom side) with bearing rails or segmented adapter frame from M+W Products, optionally installation from top (plenum side) – Optional components: Prefilter, AMC filter, cooling coil/ heating coil and air diffuser on the cleanroom side, Test Aerosol Device
