Match up the bayonet fittings on the filter holder 

and the Remote Filter Holder and turn ¼ turn 

clockwise until it locks into position. 

1/4 turn

 

Fit a single or twin breathing hose between the 

SR900 respirator and the Remote Filter Holder, 

fit the mask to your face and tighten the 

waistbelt. 

 

 

Prepare for use in welding 

The remote filter holder is ideal for use in 

welding. 

When the assembled equipment is fitted, it is 

placed at your back directly behind you. This 

helps keep the filter intake away from all welding 

hazards, such as heat, sparks and toxic metal 

fumes that may be released in the welding 

process. 

 

The remote filter holder gives the SR900 

respirator a much more shallow profile, enabling 

it to easily fit inside most welding hoods or 

shields. 

 

 

A spark-proof and flame-resistant cover is 

available for protecting the breathing hose from 

heat, the arc or flame, and flying sparks during 

the welding. 

Covers are available for both both the single and 

twin hoses. 

Simply slip the cover around the hose. If 

required, fasten with the Velcro strips.
