SR900 — How to

Remove the filter and wipe the inside of the 

filter holder. Pay special attention to the groove 

in the filter rim when  cleaning. 

 

Remove the protective caps from the exhaust 

valves. Pull out the membranes and wipe clean. 

Wipe the valve seats before refitting the valves 

and replacing the protective caps. 

It is of critical importance that both membranes 

and seats are clean and intact. No dirt or grime 

must remain, and the parts must not have any 

cracks, tears or other damage. 

 

Remove the inhalation membrane from the filter 

holder or hose attachment. Clean the membrane 

and the valve seat. Replace.  

Make sure ALL valves are properly fitted. Put the 

respirator to your face and draw a few deep 

breaths to make sure that the valves are in good 

working order. 

 

If the headstrap is very dirty, detach it, clean and 

dry separately before re-attaching.  

Tip: use a toothbrush to clean the strap.
