HALFMASK:
• Respirator is designed to use the S450 fi lter system. Gas & Dust fi lters using pre-fi lter pads & pre-fi lter cover are
available to order independently of the mask.
• The respirator is not for use in oxygen defi cient (below 19% Volume), oxygen enriched (above 25% Volume).
• The mask will not protect the user in the event of fl ying debris and projections by an explosion.
• The respirator and fi lters are not designed for fi refi ghting or work with open fl ame or molten metal when ignition of
fi lters may cause toxic fumes.
• Do not use for sandblasting or for protection against contaminates not covered by the fi lter labelling. Respirator does
not protect eyes or skin against contaminates that may irritate, burn or penetrate.
• Select appropriate fi lters for the hazard encountered. See packaging for colour coding and detail of the fi lters
available for the mask. Gas and P2 prefi lter can be used to provide a combination fi lter.
• Before use, ensure all components are clean and in good condition.
• Change fi lters frequently. As a minimum, fi lter must be changed if breathing resistance increases or the smell of the
hazard sensed. Pre-Filter pads should be changed more frequently.
• The respirator should have correct fi lter for the hazard and fi t comfortably on the face. NB Beards or similar facial hair
is likely to prevent an acceptable fi t.
• The respirator should be stored in its bag, away from direct sunlight, contaminates and risk of physical damage.
FILTERS:
• Filters can be fi tted to the S450 halfmask.
• Two fi lters of the same type should be used and changed at the same time.
CHANGING OF FILTERS:
• To apply the fi lters, align the arrow on the fi lter (image symbol A) to the arrow on the mask body (image B). Push the
fi lter on to the mask (image C) and turn the fi lter clockwise until you feel it lock into position (image D).

• To remove the fi lter simply twist it anti-clockwise until you feel fi lter become loose. The easiest and most effi cient
way of replacing fi lters is with the mask removed from the face. If you need to remove and refi x the fi lter to the mask,
please check the integrity of the foam seal before re-attaching the fi lter. if the seal appears damaged, OX recommend
that the complete fi lter is replaced. Application of fi lter may be easier if inner plastic shell is supported with users’
hand from inside the mask to prevent the part coming away from the rubber body. Dispose of used fi lter hygienically
& safely.
• NB Check your fi lter has a gasket attached to the base of its locking feature. If this is missing, please contact OX.
CHANGING THE PRE-FILTER PAD:
• The P2 pre-fi lter pad can be used to convert a gas fi lter into a combination gas and dust fi lter. It must not be used on
a P3 dust fi lter. To change the prefi lter, remove the cover, dispose of the used pre-fi lter pad, hygienically and safely.
Insert a new pre-fi lter pad and re-fi t the cover.
CHANGING FILTER CARTRIDGE:
• Remove pre-fi lter cover and unscrew fi lter cartridge. Remove from mask together with connector and dispose of
hygienically & safely.
• Clean respirator. Re-fi t new fi lter. Ensure foam sealing ring is undamaged when fi tting fi lter, if damaged, replace fi lter.
