1. Overview
The Laminar Flow Hood is designed to provide a working space that meets a certain level of
cleanliness for critical applications such as nanofabrication, or microbiological applications.
These working spaces are often dened as a controlled environment or clean zone rather
than a cleanroom. Typically, the cleanliness of the system is dened in one of two ways, via
ISO 14644 Cleanrooms and Associated Control Environments or the FED STD 209E Airborne
Particulate Cleanliness in Cleanrooms and Cleanzones. Although the FED STD 209E standard
has been withdrawn and superseded by the ISO standards it is still often used within the
wider community and so is still referenced in the instrument and documentation.
The use of controlled environments allows users to prepare samples or perform experiments
inside an environment with a specic minimum level of control. In the case of the laminar
ow hood, this is a certain level of cleanliness dened as particulate counts. In both standards
particles are dened by their size and are grouped into bins with decreasing particle size and
increasing maximum particle density count. Table 1 shows the comparison between the two
standards and the maximum particle count per bin.

Table 1. ISO 14644 vs FED STD 209E particle count guidelines
The Ossila Laminar Flow Hood operate at ISO Class 5 cleanliness, this cleanliness is dened
by the design of the system and the ltration used. For most ISO Class 5 systems HEPA lters
are used typically of class H13 but some use H14 for a ner ltration. Higher degrees of
classication can be reached using ULPA ltration, using either U15 or U16 lters.

It is these lters that allow the system to operate and generate a clean environment. The
general principal behind the laminar ow hood is that air is passed through a lter which
remove particulates from the air. This air is then passed over a surface at a speed which
ensure air ow is unidirectional and laminar, rather than turbulent. This allows dirty air to be
ushed out of the environment and creates a curtain of clean air that stops inltration of
particulate from the external environment. Operating in the laminar ow region also ensures
that pockets of recirculating air are not formed which could trap particulates within it.

3.Safety
3.1Warning
3.2 Use of Equipment
The Laminar Flow Hood is designed to be used as instructed. It is intended to be operated in a
laboratory environment and is designed to be used in the following environmental conditions:
•Indoors in a laboratory environment (pollution degree 2)
•Altitudes up to 2500 m
•Temperatures of 5°C to 40°C; maximum relative humidity of 80% up to 31°C.
The equipment is supplied with a power cord (and if necessary, an additional power transformer) for
the country of purchase, in accordance with European Commission regulations and British Standards.
Use of any other electrical power cables, adaptors, or transformers is not recommended.
3.3 Hazard Icons
The symbols shown in Table 3.1 can be found at points throughout the manual. Note each warning
before attempting any associated operations.
•Only use the power cord (and transformer) supplied with the unit.
•Mains inlet rated for 110-230V ± 10%. For 110V mains supplies, use provided
transformer.
•The unit must be connected to an earthed power outlet.
•The equipment should not be disassembled by users beyond the state it is
shipped.
•Two people should be present when moving or assembling the laminar flow hood.

3.4 General Hazards
Before installing or operating the Laminar Flow Hood, there are several health and safety precautions
which must be followed and executed to ensure safe installation and operation.
WARNING: Improper handling when operating or servicing this equipment can result in serious injury.
Read this manual before operating or servicing this equipment.
I. DANGER: DO NOT use the Laminar Flow Hood in the presence of an explosive
atmosphere.
II. WARNING: To avoid electrical shock or injury, do not disassemble the bae or
electronics case or try to access any internal parts of the bae. Servicing should only
be carried out by a trained professional. Before servicing, disconnect the power cord
and wait 10 minutes (high voltage may persist in capacitors for some time after removal
of power).
III. CAUTION: The Laminar Flow Hood uses a ground-type power plug, which must be
connected to an earthed outlet to prevent electrical shock. The Laminar Flow Hood will
be supplied with an earthed plug appropriate for the country of purchase.

11
IV. CAUTION: The Laminar Flow Hood has a high voltage source. Do not attempt to open
the unit.
V. CAUTION: The Laminar Flow Hood is heavy, movement and assembly should be done
with two people.
3.5 Power Cord Safety
I. Emergency power disconnect options: Use the power cord as a disconnecting method
and remove it from the power source. To facilitate disconnect, make sure the power
outlet for this cord is readily accessible to the operator.
II. Only use the power cord supplied with the Laminar Flow Hood. Using an unearthed
plug may result in serious injury or death.
3.6 Servicing
I. Routine replacement of the lters is recommended to ensure ecient running of the
Laminar Flow Hood. Filters act as accumulators and appropriate PPE should be used
when removing old lters to minimise exposure to any potential hazardous materials
collected by the lters.
If servicing is required beyond routine servicing, please return the unit to Ossila Ltd The warranty will
be invalidated if:
•Modication or service has taken place by anyone other than an Ossila engineer.
•The Unit has been subjected to chemical damage through improper use.
•The Unit has been operated outside the usage parameters stated in the user documentation
associated with the Unit.
•The Unit has been rendered inoperable through accident, misuse, contamination, improper
maintenance, modication, or other external causes.
3.7 Health and Safety – Installation
I. The nal assembled Laminar Flow Hood is heavy, two or more people should be used
to move the system into place.
II. The bae should remain disconnected from the mains electrics until the Laminar Flow
Hood is fully assembled. Doing so before complete assembly may result in serious
injury or death.

12
3.8 Health and Safety – Operation
I. UV radiation can cause severe burns to the eyes and skin. An integrated passive
infrared sensor detects when users are nearby and pauses the operation of the UV
light. Acrylic side panels act as absorbers of emitted UV however radiation can escape
through the front opening. As a precaution, never look directly into the Laminar Flow
Hood when the UV light is on.
II. When using the Laminar Flow Hood only non-hazardous activities should be
undertaken within the hood. Airow of the unit is designed to move air from the
experimental area to the user. This will not provide protection to users from activities
within the hood.
III. The Laminar Flow Hood bae has a high voltage source. Do not attempt to open the
unit.
IV. Do not use any open ames within the laminar ow hood.
3.9 Health and Safety – Servicing
I. Service or installation work that includes integrating electrical components should only
be performed by an Ossila engineer. Never alter the wiring of any purchased
equipment. If changes are made, such alterations may damage the equipment, cause
injury, or even death. At the very least, such alterations will void your warranty.
II. If the fuses located in the fuse drawer at the back of the unit need changing, the unit
must be placed in a safe mode by switching the unit o and disconnecting the power
cord from the power socket.
4. Unpacking
4.1 Packing List
The standard items included with the Laminar Flow Hood are:
•Bae Assembly
•Electronic Case Assembly

13
•Two Acrylic Side Panels
•One Acrylic Front Window Sash
•Stainless Steel Tray
•Back Panel
•Assembly Kit and Instructions
•Power Supply Cord
In addition to these items, customers who live in countries where the voltage of the mains power is
110 V will have a step-up transformer which can be used to increase the voltage supplied to the system
to 220 V.
4.2 Damage Inspection
Examine the components for evidence of shipping damage. If damage has occurred, please contact
Ossila directly for further action.
