AAF-CR II Module

Installation:

The CR II module is suitable for installation of high efficiency particulate air filters, such as MEGAcel II and AstroCel II filter. The total installation height is up to 400 mm only. This housing is designed for use in areas where air quality has to be of extremely high-level.

The CR II module can be assembled to form an air-supply ceiling suitable for used extensively in hospital areas like operation theatres, associated preparation rooms, intensive care wards, and for class 1 areas as defined in DIN 1946, Part 4 (1989). Air quality at the supply i.e, at grill level will be Class 100/ISO Class 5(at rest condition)

The CR II module can also be used individually or as an air-supply ceiling in production areas in the pharmaceutical, food, and cosmetic industries as well as laboratories. The AAF CR II adheres to the guidelines illustrated by AISI.

Construction:

The CR II module is made of high quality AISI stainless steel/GI/Aluminum and is characterized by its rigid, airtight construction. This module is connected to the air supply duct by a circular connecting inlet on side of the housing. The HEPA filter (MEGAcel II or AstroCel II) is positively positioned with the help of latches or locking clamps.

Laminar Air Flow Diffuser:

The diffuser has an installation height of only 20 mm. A stainless-steel/GI perforated plate with 55% free surface area is supplied as standard. As an option 35% free surface area diffuser can be offered.
