WARNING
Only close observance of the instructions laid out in this booklet can guarantee, perfect service and
safe use of
AC
respirators.
SPASCIANI S.p.A.
and its appointed agents take no responsibility for damages which may occur due
to incorrect or inappropriate use of respirators nor following maintenance carried out by un-authorised
people.
Breathing protectors must always be used by trained people under the supervision of personnel well
aware of the limits of application and of the laws in being.
The use of non-original accessories or spares voids the approval.
GENERAL
The air line respirators are efficient protective devices for respiratory organs in many industrial processes. In
some cases they also specifically protect some parts of the body more likely to be exposed to the mechani-
cal action of the abrasive blast (ACS) or to contact with chemical substances.
The weight reduced to a minimum, considering the protection and the durability required, and the ergonomic
design make these apparatus easy to use and comfortable to wear.
The respirators must be fed with breathable air according to EN12021, the feeding pressure shall be between
5 and 6 bar and the minimum flow for every operator shall be of 250 l/min.
When feeding air line breathing apparatus, the use of big factory multi-purpose compressors should be avoid-
ed: not only is the air hot and oily, but it can also carry gases originated by the combustion of lubricant.
We therefore suggest to set up a small, independent system with suitable filtering units, to supply compressed
air at approx. 5 to 6 bar via suitable pressure reducer.
Air line respirators type
ACS 952
and
AC 190
are
approved and marked according to the European
Standard
EN14594
and as follows classified:
ACS 952-EN14594 - CL.4B / AC 190 - EN14594 - CL. 4 B
.
ACS 951
respirator, which is provided with a hybrid full face mask / hood, is
marked being assessed
directly against the essential health & safety requirements of the annex II of the PPE directive 89/686/CEE;
EN14594 (class B) standard being anyway partially used for the certification wherever applicable.
Just after the flow regulator
AC 95
, the filter silencer
EOD 55
, reduces the noise generated by the airflow and
at the same time retains any odours and fine particles that may be present in the air.
SPASCIANI S.p.A.
supplies a filtering unit that can be wall-mounted or transportable. This is made of a pres-
sure reducer, a coalescing filter that retains droplets and a carbon filter that absorbs oil vapours.
The use of this unit does not avoid the need for
EOD 55
filter.

LIMITS OF APPLICATION
• The hood of
ACS 951
and the mask
TR 82
or
TR 2002
of
AC 190
allow the use of a safety helmet worn
outside, if head protection is required.
•
ACS 951
hood, made of fabric and plastic material, is not designed to protect from chemicals and shall be used
only to protect from the projection of abrasive particles in sandblasting, scraping and grinding operations.
• The
ACS 951
face piece is a full face mask / hood hybrid that should be used only where the workplace
conditions (access, position or ergonomy) do not allow the use of
ACS 952
or
AC 190
.
•
ACS 951
and
AC 190
respirators are not suitable for bearded persons, since the beard impedes the tight-
ness of the mask on the face.
•
ACS 951
and
AC 190
respirators cannot be used by persons wearing side arm spectacles. With
AC 190
,
though, it is possible to fit special frames for prescriptions lenses into the mask.
• The
ACS 952
hood is not designed to protect the head, with the exception of minor impacts.
•
ACS 952
as far as the visor is concerned, exceeds the requirement of EN166 (Par. 7.2.2) for high impact
resistance (120 m/sec).
