PRINCIPLES OF OPERATION
Air is drawn into the cupboard at the working aperture Abelow the sliding sash at a
velocity high enough to ensure entrainment of any fumes/odours given off by the
processes carried out within the cupboard.
The fumes from within the cupboard are carried by the moving body of air through the
cupboard Bto the pre-filter Cand main filter Dto absorb vapours and other noxious
fumes/odours before being expelled by the exhaust fan Eas clean air F.
The fan E, which is mounted below the main filter exerts a negative pressure on the
internal space within the cupboard B. This in turn pulls external air into the cabinet through
the working aperture Aand keeps a constant circulation of pre-filtered clean air passing
through the cupboard whilst ensuring that noxious odours are trapped and adsorbed by
the main filter.

SPECIFICATION
Definition: The Airone 1000RS/E Mobile Filtration Fume Cupboard has been designed
to comply with BS7989:2001 for filtration fume cupboards along with
Building Bulletin 88 from the Department for Education and Employment and
has been tested by CLEAPSS.
Application: The unit gives maximum flexibility and can be manoeuvred between
different locations. A counterweighted sliding front sash and clear laminated
glass sides and rear provide 360° all round visibility making this ideal for
demonstrations. Lowering the sash will reduce the airflow and therefore
noise is reduced to a minimum benefiting demonstration.
Construction: Aluminium extrusions and mild steel sheet, welded and painted in epoxy
powder coat, Light Grey RAL-7035 and White RAL-9016. The fume
enclosure is laminated safety glass.
The top panel and rear baffle are clear acrylic.
The suspended/counterweighted front sash is in laminated safety glass with
an epoxy powder coated extruded aluminium handle.
The work tray is white polypropylene as standard.
Sash Operation: The vertical sliding laminated glass sash of the AIRONE 1000RS/E fume
cupboard is suspended and counterweighted providing added advantages
over fixed-sash or folding sash fume-hoods. E.g. the sliding laminated glass
sash can be closed and this provides protection to operators.
The vertical sash conforms to Paragraph 4.12 of the Building Bulletin # 88 of
the DofEE (Rev. of Design Note # 29) and BS:7258 requirements in that the
sash cannot fall if one of the suspending cable-cords is cut.
Moving the vertical sash upwards and downwards causes the fan to speed
up or slow down to give a constant face velocity, this is controlled by a micro
switch.
Filter Housing: The filter housing is located above the lower cabinet doors and contains the
main filter and pre-filter.
Storage Area: Located at the bottom of the unit and accessible by hinged doors with
magnetic catches.
VAV System: The unit has a VAV (Variable Air Volume) system incorporating a filter
saturation alarm. The VAV system ensures that the inflow is constant at
variable sash heights. The control panel is located on the RH side cabinet
aerofoil.
ON/OFF Switch: Illuminated green, and located on the RH side cabinet aerofoil above the
electronic VAV control panel.
Supply: 230V 50Hz - 0.9 A (excluding electric socket load).
Performance: The average inflow at the working aperture is 0.4 m/s.
The minimum working aperture is 200mm high.
The maximum working aperture is 365mm high.
Noise level: 59 dBA

MAINTAINANCE AND PERFORMANCE MONITORING:
This fume cupboard is a ‘portable appliance’, powered by mains electricity and it complies with EN-
BS-61010. The correct fuse (10A) must be fitted to the mains plug and this and other exposed
parts of the electrical system should be examined frequently for obvious damage. There should be
regular formal inspections including earth bonding and insulation testing.
Your Airone 1000 RS/E Mobile Fume Cupboard should have an annual service by a suitably
qualified person, to maintain it’s good condidtion and reduce the possibility of hazard to the
operator.
We recommend that a service programme be arranged with Safelab Systems ltd.
Regular maintenance by our qualified personnel will ensure safe running of your equipment
and also ensure that you meet your requirements under COSHH regulation 9.
The minimum requirement to comply with COSHH Regulations is that the face velocities and filter
efficiencies must be monitored (at least once every 14 months) and a written record kept of the
results. Tables printed on the back pages of the Operational Safety Log-Book are suitable for
keeping these records.
Refer to page 14 for face velocity and filter checking procedures.
It is also recommended that the pre-filter be replaced a minimum of once every 3 months.

MAINTAINANCE AND PERFORMANCE MONITORING (CONTINUED):
INSTRUCTIONS FOR FACE VELOCITY MEASUREMENTS
(Record results on record form - page 15 )
PROCEDURE:
Imagine the face of the fume cupboard divided into
nine cells.
Stand as far as practicable from the fume
cupboard with the sensing head in the plane of the
sash and take airflow readings at approximately
the centres of each of the nine cells.
Record for each cell the approximate average reading over a period of at least ten
seconds, applying any corrections from the air flow meter calibration chart.
Look at the table and repeat any reading which seems to be very different from the
general pattern. Record the average of this and the previous reading.
CALCULATION:
Minimum face velocity -
Record which of a, b,c,d,e,f,g,h,i, is the smallest, i.e.: the minimum face velocity.
If it is below 0.3 m/s then containment factors are impaired and the cause will have to be
found and remedied.
VARIATION:
Check for variation as follows :
Add together the values a,b,c,d,e,f,g,h,i and divide by 9 to get the average.
Find the biggest and smallest of a,b,c,d,e,f,g,h,i.
The upper percentage variation is the biggest minus the average, divided by the
average and multiplied by 100.
The lower percentage variation is the average minus the smallest, divided by the average
and multiplied by 100. Each of these should be below 30%, if not, then the Airone 1000RS
has been parked in an unsuitable site and will have to be moved. (see page 10 for siting
guidance.)

MAINTAINANCE AND PERFORMANCE MONITORING (CONTINUED):
INSTRUCTIONS FOR FILTER SATURATION TESTING.
Regular filter checks and monitoring (once a week is recommended) to test quality of the
air breathed in by operators and filtration efficiency. Filter challenge tests can be carried
out during routine Service and Maintenance procedures once every 6 months as
described in the Operational Safety Log Book.
The recommended procedure for testing the efficiency of the system requires a GASTEC
Volumetric Detector Pump and Gastec Chemical Detector Tubes. Test the quality of air by
sampling at eye and mouth level at regular intervals once a week with Gastec tubes
calibrated for the particular compound in concentrations below its respective OEL
(Occupational Exposure Limit) MEL (Maximum Exposure Limit) or OES (Occupational
Exposure Standard (or MAK in Germany and/or TLV in the USA).
Please refer to the Chemical Listing, Adsorption Index and Gastec Detection Guide
published in our Operational Safety Log-Book.
CLEANING
The materials used to construct the Airone 1000RS/E Mobile Fume Cupboard have been
selected to give maximum durability and a long life. It is beneficial however to regularly
clean and decontaminate the internal and external surfaces.
It is recommended that the cabinet is switched on during any cleaning procedure and that
suitable protective clothing (face-mask, gloves and safety glasses) is worn.
All surfaces should be cleaned with a mild detergent solution then finished off with a damp
cloth and wiped dry.

TROUBLESHOOTING
1. What if I can smell the vapours or gases being used in the procedure?
Filters have a high efficiency but, because the nose is very sensitive, the residual gases
passing through the filter may sometimes be smelt, even though their level is not
hazardous. If the gases are causing distress, the operation should be finished and the
degree of filter saturation monitored.
2. What if I can smell the vapours or gases being used in the procedure,
but I have checked the filter performance and it is satisfactory ?
Check siting of the cabinet to ensure that nothing is being allowed to escape out through
the sash. Fume containment is easily impaired by draughts from windows, doors or fan
heaters and air vents.
3. What if there is a release that the filters of the Airone 1000RS cannot contain?
If the initial chemical hazard analysis or risk assessment (under COSHH) has been carried
out correctly resulting in correct selection of appropriate types of carbon filters followed by
weekly air sampling and filter monitoring checks this is unlikely to occur. In case it does
happen, due to accidental release of gas or vapour or an unexpected spillage, then leave
the fan running and evacuate the area. Subject to the hazard assessment and local
considerations, it may be that personnel with breathing apparatus would have to return to
open windows and ensure that all hazardous vapours or gases had been dispersed.
It is recommended that a replacement carbon filter is kept available at short notice for such
an event.
WARNING:
If a spill exceeds the capabilities of the Airone 1000RS/E, it is likely to exceed the
capabilities of carbon filtration face masks. This means that only an air or oxygen cylinder
based breathing apparatus could provide adequate protection.
