Page 4: Overview
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 defined by the design of the system and the filtration used. For most ISO Class 5 systems HEPA filters are used typically of class H13 but some use H14 for a finer filtration. - Page 5 It is these filters that allow the system to operate and generate a clean environment. The general principal behind the laminar flow hood is that air is passed through a filter which remove particulates from the air. This air is then passed over a surface at a speed which ensure air flow is unidirectional and laminar, rather than turbulent.

a set distance. Once the UV light is turned on through the quick settings menu the system will monitor for motion in front of the system, it will immediately turn off the UV light if movement is detected and will keep it off until there has been 30 seconds without motion detected within a 1.5m distance. The UV light therefore can be in one of three states and the blue light on the front of the unit will display what state it is in. -

Figure 8.6 Filter menu and reset options. The about menu provides information about the system to the user this shows the current software version number of the instrument. Figure 8.7 About menu in settings. 8.8 Filter Change Menu When changing the filter, the user will be required to navigate to the filter settings page and select the filter change option. - Page 40 Figure 8.8 The filter reset process after completion. Once complete the system will save the new baseline back pressure and use this to reference the current back pressure against in determining the current level of filter saturation. The default saturation percentage is a percentage increase in the baseline back pressure. So for example if the baseline back pressure is 100pa and the current measured back pressure is 135pa this would be a saturation of 35%.

Page 41: Maintenance
9. Maintenance 9.1 Cleaning Maintenance consists of routine cleaning of the inside of the cabinet for the purposes of decontamination. It is recommended that a solution of 70:30 ethanol to water or 80:20 isopropyl alcohol to water is used. This should be liberally sprayed to all interior surface of the hood, excluding the filter face and the electronics case. -

Additional pre-filter discs cut to size can be purchased from Ossila. Alternatively, users can purchase any pre-filter they wish, it is recommended that a minimum filter grade of F8 or F9 should be used. - Page 43 2. Turn off the power to the system ensuring that is completely disconnected. 3. Open the plenum access panel that can be found on the side of the plenum using the 2.5 mm hex key provided. Figure 9.3.1. Remove the filter access panel on the side of the plenum.
- Page 44 Figure 9.3.3. The HEPA filter should be lifted and slid through the cut out behind the filter access panel. This can then be removed from the side of the unit. 7. Place the filter inside of a clear plastic bag and seal it with tape. This should then be disposed of in a suitable waste stream.
