USING THE COMPRESSED AIR BREATHING APPARATUS 

 

 

AirMaXX classic 

25

 

3.11.2. Pressure Reducer with 

alphaCLICK 2 

(1)  Place the compressed air breathing apparatus in a horizontal position with 

the cylinder facing up. 

(2)  Hinge up tension clamp at cylinder strap (

 Fig. 11) and thus loosen the 

strap. 

 

 

When exchanging compressed air cylinders of the same diameter 

(without attached bumpers), only the tension clamp needs to be 

opened. 

 

(3)  Close cylinder valve(s), release air from pneumatic system of the SCBA with 

lung governed demand valve. 

(4)  For compressed air cylinders with 

alphaCLICK 2

 turn the handwheel on the 

coupling side (arrow 1) in a clockwise direction first (

 Fig. 16) and then, 

when closed up to the stop, push downwards in the direction of the pressure 

reducer (arrow 2). 

 

Fig. 16 

Removing a cylinder with alphaCLICK 2 

 

The cylinder adaptor releases from the 

alphaCLICK 2

 coupling. 

 

 

Attention! 

Do not remove the compressed air cylinder(s) from the cylinder strap or 

transport the compressed air cylinder(s) by the handwheel. 
This could accidentally open the cylinder valve. 

 

(5)  Lift compressed air cylinder(s) at the valve and pull out of cylinder strap.
