1. Field of application and conditions for use
The MK12 powered respirator is used for dust removal and
partial odour removal, not for gases or vapors and is used to
reduce or remove resistance to inhalation during respiration by
producing a constant airflow. The unit is designed with
manufacturer’s minimum design flow rate 170 litres,210 litres
or 250 litres per minute (the flow rate at which the equipment
still will fulfill the requirements of the class in EN12941). The
actual working time will be about 8 hours.
2. Description
A complete powered respirator apparatus consists of:
◆Blower master unit, provided with a dust P3 filter, a steel
pre-filter and an activated carbon filter (chart 1), supplied with
a belt and a comfort plate.
◆Rechargeable battery, which is equipped underside the
apparatus.
◆A hose with a bayonet connector to blower unit and a bayonet
connector to mask,
◆Battery charger, fully automatic.
3.Use
The MK12 unit supplies an overcapacity of clean and filtered
ambient air, which is fed to the mask. It allows the user to breathe
in air without himself having to overcome the resistance of the filter.
Considering that an adult person requires some 50 litres of air per
minute, the overcapacity ensures an overpressure and thus a high
degree of protection.
Chart 1
With a fully charged battery the unit will operate for about 8
hours. The unit contains a warning facility to warn the user
against reduced air supply, due to clogged filter or low battery.
3.1Prior to use
Before using the powered respirator, the user must ensure that
all the conditions for safe use have been satisfied. See below
for the applicable statutory regulations and rules.
◆Check that the appropriate hose connector is fitted to the hose
◆Check before use that the battery is sufficiently charged and
that the free flow of air is not obstructed by a blocked hose or
other causes.
◆Check that a set of filters is fitted correctly.
◆Check that the lock of the battery box and the lid filter housing
are closed.

3.1.1 Usage limitations system
◆The space in which the unit is to be used must contain at
least 17% oxygen and must not contain any explosive gases or
vapors. In enclosed spaces where there is a risk of oxygen
deficiency, use of the unit should be avoided.
◆In case of physical effort, it is possible that a temporary
negative pressure occurs in the blower unit, resulting in a
reduction of the protection factor of the system.
◆Air speed in excess of 2m/s can affect the protection factor.
◆The ambient usage temperature should be between the limits
of -5 and +50
◆Do not use the unit in circumstances where hazardous gases
and/or vapors are present.
Warning
If the wearer of the respirator feels dizzy or uncomfortable or can
smell/taste something, he should abandon the contaminated area
immediately.
3.1.2 Usage limitations filter element
◆Used filter elements cannot be cleaned.
Warning
Never attempt to clean a filter element; the filter media may be
damaged, resulting in loss of protection.
3.1.3 Charging batteries
The battery is supplied in a non-full charged state; the charging
time for a fully discharged battery is approximately 3 hours.
The automatic setting of the charger prevents damage to the
batteries when the charging time is exceeded.
Under normal circumstances the battery can be charged and
discharged approximately 500 times.
After the battery is completely charged, the charger will switch
over to trickle charging. This will expand the lifetime of the
battery beyond 500 charge cycles. If the unit is used for more
than 8 hours a day, it is recommended that user carry a second
battery for backup.
Batteries may be charged on or off the unit.
3.1.4 Filter assembling
Open the front cover by releasing the retaining clip on the side
of the unit by hand (do not use tools). Fit the filter squarely into the
power unit by aligning the three concave points of the filter box to
the three convex points in the cavity. Then press the filter hard and
rotate a small angle clockwise to lock. To unlock the filter, press it
and rotate anticlockwise.
The pre-filter and the activated carbon filter should be installed
on the inner side of the upper cover, assembled in the order and
direction indicated in Figure 1, and then pressed by the frame.
Three notches on the frame are aligned with three buckles on the
top cover. Press the frame and rotated clockwise to lock. To
disassemble them, press the frame and rotated anticlockwise to
unlock.
3.2Switching on
The unit can be switched on by pushing the ON/OFF button for
about three seconds. An alarm signal will be heard, and the
LCD will display the real statuses of air flow, filter and the
battery power. Then the unit will start on the low speed.

3.3During use
This product has three levels of air flow. By shortly pressing the
" SET" button, the flow level will change according to "low -
medium - high - low..." circulation accompanied by an alarm
signal. The icon on LCD also changes synchronously. At the
same time, the digit on LCD indicates the real air flow rate. If
during use the air supply drops or fails entirely, leave the work
area immediately. If a signal for low battery (2 beeps repeatedly)
or a clogged filter element is given (a single short beep
repeatedly), leave the workroom immediately, and check
according to chapter 6.
3.4After use
By pressing the ON/OFF button for 3 seconds, the motor will
stop gradually accompanied by a long tweet. When the icons on
LCD disappeared after about 15 seconds, the apparatus will turn
off completely.
Cleaning and disinfecting
After each session clean the unit, using a mixture of water and
a mild detergent. Subsequently, rinse thoroughly with clean
water. Do not use any solvent. During cleaning ensure that no
water can enter the apparatus. The unit must not be immersed
in fluid. Dry the unit with a cloth and/or leave it to dry in the
open air.
Advice
For reasons of hygiene each operator should be equipped with
their own hood or mask.
4. Maintenance and inspection
Prior to use: functional checks for the user
After use: Cleaning and disinfecting of the blower unit.
Cleaning, functional checking of the complete
system.
Every 6 months: Cleaning and disinfecting of the blower unit.
Cleaning, functional checking of the complete system. Check
the hose for leakage and inspect the connector for damage.
5. Storage
Before storing the unit in the carrying case, it should be
thoroughly dry.
Do not keep soiled filter together with the unit and the mask in
the same enclosed storage space.
Remove the filters from the unit and seal them appropriately.
The unit is only recommended for storage in the temperature
range -10℃to +55℃and in conditions where relative humidity
does not exceed 85%.
