Laminar flow hoods

Laminar Flow Hoods – Flowbox, cleanroom cabins, cleanroom hoods.

Laminar flow provides almost complete control and eliminates all suspended particles. Laminar flow is a highly purified air flow at a uniform rate of 0.45 ± 0.1 ms over the work area to be protected. Laminar flow units are fitted with special HEPA filters.

• With pre-filter
• Main filter for cleanroom class 5/10/100
• Customer-specific dimensions available
• Ceiling or frame-mounted
• Cleanroom size according to customer requirements
• Circumferential strip curtain in PVC, acrylic glass or safety glass
• Ventilation module, radial fan with very low vibration and automatic adjustment
• Pollution-monitoring filter

Modules with vertical air ducts are designed for wall or ceiling mounting.

Ambient air is drawn in by the fan via a pre-filter, then passed through a HEPA filter on the cleanroom side.

Laminar flow hood features :

Grey molded plastic housing, aluminum frame, frame and ceiling suspension possible.

• EU quality class 7 pocket pre-filter, washable (40% ASHRAE)
• Air velocity 0.45 m / s measured at a distance of 15 cm from the top of the filter
• Class EU 14 laminar flow filter, separation efficiency > 99.999% at 0.3 µm particle size. Class 100 cleanroom
• Manufactured to US Federal Standard 209 and VDI Regulation 2083.

Options for our laminar flow hoods :

• Versatile transparent PVC strip curtain that can be installed under clean air modules
• Design of entire cleanrooms
• Cooling module with heat exchanger element to compensate for the resulting thermal load

Laminar flow hood filter:

The individual filter bags, which consist of several base units to form a filter wall, are tightly connected to an easily replaceable frame. Thanks to spacer strips on each individual bag, overlapping of filter surfaces is prevented and a favorable increase in resistance over the operating time is ensured. The filters have a high dust-holding capacity and comply with EU quality class 7.

Laminar flow cooling section:

The cooling module of the laminar flow hood compensates for the resulting thermal load of the system and maintains the required temperature.

Fan module.

Direct-drive radial fans are used. They are continuously controlled via a control unit. The ultra-low-vibration fans are quiet and have a flat noise level profile.

Laminar flow filter:

The filter’s filtration efficiency is of paramount importance, but so is the formation of a laminar airflow in the work area. That’s why laminar flow filters are a must for cleanroom applications.
