This Air Wave PAPR blower unit has been designed primarily to function with the TC180 Digital ADF welding mask PAPR hood, the filter / blower unit could possibly be used with other masks with the same connection but the approval would not cover such use because the approval is based on the complete system.
Depending on your work tasks and requirements your Noz-Alls Airwave filter blower may be preset to any of the six air flow rates from 170 l/min, 180 l/min, 190 l/min, 200 l/min, 210 l/min & 220 l/min, in practical trials most users ran the mask at 170 l/min and found that flow level sufficient even when welding heavy section multiple pass MAG welds and this was being undertaken for 8 hours a day. The air flow rate chosen will of course be down to personal preference, plus dependant on the weather, in the height of summer you may find it necessary to increase the air flow rate to ensure you remain comfortable.
No other PAPR welding mask filter unit provides you with 6 flow settings, this helps to ensure you always remain comfortable. The flow settings do not need to be checked with a flow tube as the system self tests and maintains the flow required / set.
Functional testing is required as a matter of good operating practice and is simply achieved using the "Flow Test Blind" supplied and laying the blind over the AirWave blower unit inlet grill. The system automatically moves into checking mode resulting in the motor increasing in speed so as to overcome the obstruction / clogging, when this is not possiblle the alarm will be triggered. Remove the flow test blind from the grill and the system will return to normal, the alarm stops sounding and the flow returns to the pre-set level.
In a similar fashion, blocking the outlet pipe to blower unit tests the blower once agian with a similar effect the result being that the blower ramps up the speed to try to overcome the resistance and maintain the set flow, when this is not possible the alarm is again triggered and the test complete, removing the obstruction returns the blower to normal condition. The Alarm will take a few seconds before it stops sounding.
Your AirWave PAPR main filter power unit is supported by a wide belt which makes the filter unit as comfortable as is possible to wear, the filter unit may be worn round your waist and positioned on your hip or towards your back. When worn on your back this PAPR system may be fitted with a back and shoulder harness to help provide extended periods of comfort. The Harness is available separately. (Included when the system is purchased complete).
The clean air filter unit makes use of a light weight Lithium Ion battery, you will be surprised that being so light the battery will last for 10 hours of constant use (170 l/min),
the weight advantage has been gained by making use of good quality power batteries. The battery will fully charge in 4 to 5 hours using the charger supplied. When disconnected for charging the battery has a digital LED charge level meter indicating the charge level from 0 to 100%.
The main filter unit makes use of a spark protector fitted just behind the air inlet grill this is followed by the pre-filter mat after which comes the main HEPA filter, the operational filters are not expensive to replace which makes this PAPR AirWave Fliter Blower unit economical to run.
The main filter blower unit is intelligent and will maintain your set flow rate as the filter becomes clogged with debris from welding fume, However should a rag or a piece of paper fall or be sucked against the filter inlet grill thus preventing the filtering air flow the motor will initially ramp up the motor speed in an effort to maintain the air flow to your face, not being possible the filter will alarm (beep) & vibrate to bring your attention to the fact that the inlet grill has become blocked.
The LED display will also read 100% clogged!
Your Air Wave PAPR filter unit is very simple to control and set using only two control buttons, a red “off” and power reduction button plus the Green “on” and power increase button.
With the battery charged and clipped in place on the blower unit a long press on the green power button will start the filter unit – a beep and vibrate signal that the press has been acknowledged and the blower has started.
The LED display shows the following information:-
The Air Wave blower unit utilises a detachable filter housing and grill which makes filter replacement simple, quick and really easy. A press of the button at the side of the grill of the filter cartridge releases the edge, the cartridge pivots away and disconnects from the main body which provides access to the filters.
With clean hands plus work on a clean bench – use clean workshop paper roll to work on,
Place the filter grill cartridge face down on the clean surface, lift out the main HEPA filter, put to one side – remove the pre-filter and put straight in a waste bag or bin, lift out the spark arrestor and wipe clean as necessary. Clean the inside of the filter grill cartridge. Wash hands or wear a new pair of disposable gloves before touching the spark protector or the new pre-filter. Re-fit the spark arrestor and fit a new clean pre-filter – refit the main filter assuming it does not yet require replacement.
Locate the left hand edge of the filter grill into the blower unit and pivot back to the body until the grill and filters “click” into place.
The air feed hose socket has a bayonet fitting into the top of the blower unit, which just requires the hose to be twisted by 15 degrees to lock the hose in position.
The air feed hose is available as a separate item and is not included with the filter blower unit.
