The cabinets offer the highest product protection. The vertical or horizontal Class 100 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 DLF is a high-quality product constructed with high-grade components and materials, with new techniques, such as:

n          Microprocessor control with a LCD display for the Interface with the user;

n          Automatic up speeding fan; when there is increasing resistance in the filter the necessary airspeeds are maintained;

n          Window construction that can be operated manually;

n          User friendly window construction with a hinge mechanism easy to operate.

Type plate

On type plate (right upper side) there are instructions that are important for the connection of the cabinet.

Hinge-slidewindow (option)

The hinge-slide window is a tightly closing, manually operated glass or acryl window. It can be slide up or down, and open and close it by means of handgrips.

Top panel

In and behind the top panel a number of electrical components are mounted.

n          Operating panel / operating board

n          Interface board, including engine control

To check one of these components, you need to remove the pre-filter.

Worktop

The workroom contains a stainless steel (SS 304) worktop.

Plenum-construction

The plenum-construction equalizes the air trough the downflow filter.

Downflow filter

The downflow HEPA-filter* has a very high efficiency: Class H14 in accordance with EN1822. After mounting, each filter will be separately tested according to EN 12469, Annex D. Through the service panel the downflow filter can be reached.

*) High Efficiency Particulate Air filter

Pre-filter

The pre-filter is a filter in the class G4 accordance with EN779. Furthermore the pre-filter will enhance the life span of the HEPA-filter significantly.

Support frame / foot support (optional)

For a stable positioning of the cabinet we recommend the use of a support frame. For a good ergonomic work position the use of a in steps adjustable foot support is recommended. In addition, it is recommended to use an in height adjustable, well disinfectable, chair to optimize the work position. As well, the foot support will increase the rigidity of the cabinet.

Main power connection

The main power connection is positioned an the top of the cabinet. The power Gable length is maximum 3 meters and should always be accessible. See technical specifications for details.

Electronics

The electronics consists of:

n          Operational print; positioned in the top panel behind the operating panel;

n          Control print including:

•            Fuse folders (see Technical specifications for fuse-numbers)

•            Fan control

The control is free adjustable in the range between 0 % and 100 %

Air velocity compensating microprocessor regulates fanspeed to compensate for main power fluctuations and filter pollution.

•            Independent potential free Output contact.

Operating panel

The operating panel consist of:

1- Display;

2- Fundion keys (4x);

3- Fixed keys (4x);

4- Signals.

Display:

The display has 4 lines, the lowest line gives the description of the key underneath.

Fixed keys:

Function keys:

The function of keys 1,2,3 and 4 are variable. In the last line of the display the function is showed.

Signals:

TL-lighting

The TL-Lighting is mounted in the Light unit.

Fan

The electric driven double suction fan is maintenance-free.

UV-Radiator

The UV radiator is meant for disinfecting the working surface of the safety cabinet.

When the UV-radiator is on, the TL lighting will be switched off. The UV radiator can only be switched on when the window is closed, this makes sure the user will not get in contact with UV-C radiation.

The UV switch-function is only visible when the window is closed.

The UV light is be switched on through the display. It is also possible to adjust the UV disinfecting, for each day a certain disinfecting period can be defined.

When the UV is switched on, the UV hour Counter counts the lighting period. UV-Iamps haue, dependable from fabricate and type, a limit in effective running hours. Replace the lamp frequently.

Sockets

The sockets are mounted on the back wall of the working area.

They can be operated at the control panel. See "General specifications" for electrical details.
