Modular LAF Units

Faster Unit modules are vertical laminar flow units providing Class ISO 3 according to ISO 14644-1 – which can be joined together to build up small to room size clean room environments. These LAF modules can be supported by stainless steel legs or suspended from the ceiling by means of eye-bolts positioned on top of each module.

Modules are assembled side by side or joined at the head to obtain the dimensions required. Heavy duty PVC strips provide side containment to guarantee optimum efficiency of laminar airflow.

They feature AISI 304L stainless steel construction, modular designs and a wide range of sizes to provide large working areas with vertical or horizontal laminar airflow.

The H14 HEPA/ULPA filters meet ISO Class 5 according to ISO 14644-1, and are protected by a washable polyurethane foam pre-filters.

Direct driven centrifugal fans are fitted with either electronic or autotransformer speed regulation, to compensate for progressive clogging of the HEPA/ULPA fìlter.

The environment air is drawn from the top of the modules via a G3 pre-filter and then pulled downwards through the absolute H14 HEPA/ULPA filters and goes down as laminar flow into the working area. From here at floor level as well as from the front opening this air is completely exhausted.
The air is then recirculated outside the strip curtains (that have to contain the air flow) and sucked by the pre-filters in the top area.

Body structure fully made in stainless steel AISI 304L and press-bent metal sheets with a radius of 3 mm for easy cleaning and roughness lower than 0,8Ra.

Anodized aluminum filter protective grid.

Prefiltration stage consisting of G3 filtration cells made in AISI 304L stainless steel with typical arrestance of 80 ≤ Am > 90 according to EN 779.

Filtration stage consisting of main H14 HEPA/ULPA filters certified low pressure drop with typical efficiency of 99.995% MPPS according to CEN EN 1822. Filters replacement from the bottom (BR series) or from the side of the module (SR series).

Improved bag plenum design for better air flow diffusion and lower noise level. Negative pressure pattern conforming to GMP requirements to prevent risks of escape of contaminated external air – or it by-passing filter - and to reduce pressure transition losses.

Outlet for DEHS filter integrity test.

Ventilation is provided by double inlet centrifugal AC motorblower.

Electrical supply 230 V/50 Hz monophase.
