PRINCIPLES OF OPERATION
Air is drawn into the cupboard at the working aperture below 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 contaminants are entrained in the airstream, directed past the baffles within the fume
cupboard and drawn into the extract ductwork.
Heavier than air contaminants are effectively scavenged from the work surface by the low
level slot created by the back baffle.
Lighter than air contaminants are drawn upwards to the extract plenum created by the high
level roof baffle.
The extract fan exerts a negative pressure on the entire system preceding it, pulling
contaminants through the system and directing them to the exhaust stack.
The exhaust stack is under positive pressure and for standard vertical discharge the wasted
discharge cowl ensures a high velocity imparted to the exhaust. This velocity forces
contaminants to be dispersed clear of the building and surroundings.

SPECIFICATION
Definition: The Airone DS Semi-Mobile Ducted Fume Cupboard has been
designed to comply with BS EN 14175 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 (within the range of the flexible extract duct). 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 DS 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.
The fume cupboard uses an air bypass system to give a constant face
velocity at different sash heights within the working range.
Storage Area: Accessed by double doors located at the bottom of the unit.
Low Airflow Alarm: Gives a visual (red light) and audible indication of a low airflow
condition. A green light is illuminated in normal operation.
Located on the RH side cabinet aerofoil.
Supply: 230V 50Hz
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.
Services: Gas, water with remote valves with flexible connection hoses and waste
with bottle trap and flexible drainpipe (unless specified otherwise)

OPERATING INSTRUCTIONS
1. Position the Airone DS semi-mobile ducted fume cupboard where it is to be used and
lock the front castors (see page 9 for a guide to positioning the fume cupboard).
2. Connect the flexible duct to the extract duct system and clip wire tether to anchor
point on the docking before inserting the mains plug into the 13A electric socket.
3. Connect flexible gas, water and waste pipes to the docking station ensuring that the
gas and water fittings are securely pushed home and that the waste coupling is
screwed on tightly. The services can be connected at either side of the cupboard (see
photo at bottom of page).
4. Ensure the extract duct system fan is running and switch on the mains socket that
the fume cupboard is plugged in to, and allow it to run for approximately 5 minutes
prior to use.
5. Always use appropriate PPE (personal protection equipment) when using the Fume
Cupboard.
6. When working in the cupboard try and ensure that the sliding sash is in its lowest
position, and always lower the sash when the fume cupboard is not in use.
7. If using Bunsen burners, place them at least 20cm from the front sash, sides or rear
baffle.
8. Before switching off the extract fan after use allow it to run for a further 5 to 10 minutes
to make sure all hazardous vapours or gasses have cleared, and check that any
bottle are capped or stoppered and no material has been left on the necks or pooled
around the bases.
9. After use, always run cold water through the waste system, and prior to
disconnection, raise the flexible waste pipe to make sure there is no water trapped in
the pipe.
10. Disconnect water, gas and waste hoses, unclip the tether and disconnect the flexible
ducting (if required) then return the fume cupboard to its storage location. Always
replace the cap on the docking station waste fitting after use.

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 or switch fuse
spur, 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 DS Semi-Mobile Ducted Fume Cupboard should have an annual service by a
suitably qualified person, to maintain its good condition 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
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 13 for face velocity check procedures.
Safelab Systems offer Service Contracts for regular filter-monitoring and servicing of all
AIRONE Fume Cupboards. Please phone our Service Department for details. Tel. No.

MAINTAINANCE AND PERFORMANCE MONITORING (CONTINUED):
INSTRUCTIONS FOR FACE VELOCITY MEASUREMENTS
(Record results on record form - page 14 )
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.
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 20%.
