Preface
Clean Air provides a complete range Laminar Airflow Cabinets for handling of non-hazardous
materials, which require a clean particle free environment. The cabinets offer the highest product
protection. The horizontal airflow prevents contaminated outside air to enter the workstation's
work area, ensuring product protection.
Its application is in the field of pharmaceutical industry, biotechnology, pharmacies, hospital and
university laboratories as well as tissue culture and electronic laboratories.
The CLF is a high-quality product constructed with high-grade components and materials, with
new techniques, such as:
Microprocessor control with a LCD display for the interface with the user;
Automatic up speeding fan; when there is increasing resistance in the filter the necessary
airspeeds are maintained;
Integrated drain on the backside of the working surface to prevent spilled liquids to leak in
to the HEPA filter;
White laminated wooden or stainless steel (304) working surface;
All internal areas of the working space are in line with the effective HEPA filter area, to
obtain a laminar flow;
Side windows of safety glass for a good overview.
Furthermore the CLF is a service friendly cabinet, produced in The Netherlands.
We thank you for buying this cabinet and wish you good times working with this cabinet.

1Introduction
1.1
CLF
The laminar crossflow-cabinet CLF has as purpose that the working surface is kept clear of
particles by means of a clean laminar crossflow of air. By applying a HEPA-filter (High Efficiency
Particulate Air) it is possible to work in this cabinet under conditions which are sterile, dust-free, or
aseptic. The cabinet, therefore, offers a product protection.
Short description of the CLF
•At the top of the cabinet the inflow air is drawn
through a pre-filter by a fan.
•This fan blows the air in the correct proportion to
the crossflow HEPA-filter. Because the crossflow
air passed through a HEPA-filter (High Efficiency
Particulate Air), the working surface is free of
particles.
•The airflow in the workspace is crosswards, thus
preventing background air to flow into the class A
workspace.
•The air flow leaves the cabinet by the work
opening.

Maintenance and repair of the electrical cabinet
Maintenance shall only be performed by professional electro-technical service engineers, who are
sufficiently trained by Clean Air Techniek B.V. when:
They can estimate and avoid the dangers of the cabinet;
They can estimate the consequences of their actions;
They are sufficiently informed about the operation of the cabinet and the operation of the sub-
systems.
2.4
General safety aspects
1. The cabinet shall never be used unless the fan is switched into work mode and there is no
alarm.
2. When the cabinet is not used, the cabinet should be switched in to power-save mode or
closed/covered, to prevent that dust particles etc. from the room can get into the cabinet.
3. Always try to limit the amount of equipment in the workroom. Each object in the workroom
will disturb the pattern of the airflow and a large number of equipment may lead to serious
disruptions.
4. It’s is important that the cabinets will be kept clean. Even the smallest contamination which
is not visible will be easily forgotten. It is important to clean often the working area,
especially the work top.
5. Be careful with flammable liquids such as alcohol. The airflow is in the direction of the
person, so be very careful, or even better; prevent to use this kind of liquids.
6. The use of hand gloves and over sleeves is recommended.
7. Always use a chair with the correct height.
8. Transport and installation of the cabinet is only allowed for authorized staff. Please contact
the manufacturer or the seller of the products
