For advice see EN 529:2005 or AS/NZS 1715:2009. The guidance
contained in these standards highlights important aspects of a
respiratory protective device program but does not replace national
or local regulations.
1.1 Applications
The SR 307 is an attachment that enables a given facepiece to be
convertedbetweenafilteringdeviceandaprotectivedevicewith
compressed air supply.
The compressed air attachment can be used as an alternative to a
filteringdeviceinallsituationsinwhichthelatterisrecommended.This
appliesparticularlyiftheuserisdoinghardorsustainedwork,andif
thepollutantshavepoorwarningpropertiesorareparticularlytoxic.
1.2 System description
The SR 307 mounted in a Sundström facepiece is designed for
connection to a suitable source of breathable compressed air.
The pressure in the facepiece prevents polluted ambient air from
entering the facepiece.
Acompressed airsupplyhose which isapproved forbreathable
air is connected to a control valve threaded onto the user’s belt.
Thecontrolvalvecanbeusedforadjustingtheairflowratetothe
facepiece.Fromthecontrolvalve,theairflowsthroughabreathing
hose to a connection adapter, and then into the facepiece.
Thecontrolvalveisequippedwithawarningwhistlewhichwillcome
intooperation iftheairflowrateshoulddropbelowtheminimun
designflowrate.
Manufacturer’sminimumdesignflow:120l/min.
1.3 Breathable air
Breathableairshallmeetatleastthefollowingpurityrequirements
according to EN 12021:2014:
• thepollutantsmustbemaintainedataminimumandmustnever
exceed the hygienic limit value
• thecontentofmineraloilshallbesolowthattheairwillhaveno
oil smell (the threshold of smell is around 0.3 mg/m3)
• theairshallhaveasufficientlylowdewpointtoensurethatno
internalfreezingwilltakeplaceintheequipment
Intheeventofuncertaintyastowhethertheabovedemandshave
been met, a filter such as the Sundström type SR 99 compressed
air filter should be connected. Fig. 10. The SR 99 compressed air
filter consists of a pre-collector and a main filter.
The main filter consists of a gas filter section (class A3 as per EN
141:1990andAS/NZS1716:2012)withabout500gofactivated
carbon, surrounded by two particle filters ( class P3 as per EN
143:1990 and AS/NZS 1716:2012). The collecting capacity is 100
- 150 g of oil. For further particulars of breathable air, see European
Standard EN 132:1998, Australian Standard AS/NZS 1715:2009
and any other national regulations that may be in force.

El accesorio de aire comprimido Sundström SR 307 puede usarse
junto con las semicaretas Sundström, y con caretas completas de
todas las marcas provistas de rosca estándar según EN 148-1: 1999.
Una de estas combinaciones forma un aparato de respiración,
con flujo de aire continuo alimentado por aire comprimido según
EN 14594:2005.

1.1 Campos de aplicación
ElaccesorioSR307permitecambiarentreprotecciónconfiltroy
protecciónconsuministrodeairecomprimidoenunamismacareta.
Este accesorio puede emplearse como alternativa a los sistemas
derespiraciónconfiltroentodaslassituacionesenlasquesereco-
miendan estos sistemas. Sobre todo al realizar trabajos pesados o
largosycuandolacontaminacióntieneunascaracterísticasdifíciles
deapreciaroesmuytóxica.
1.2 Descripción del sistema
El accesorio SR 307 montado en una careta protectora Sundström
está previsto para acoplarse a una fuente de aire comprimido
adecuada, con aire apto para respiración. La sobrepresión que
se mantiene en la careta impide que el aire contaminado exterior
penetre en ella.
Unamangueradesuministrodeairecomprimido—aprobadapara
airerespirable—seacoplaaunaválvulareguladoramontadaenun
cinturón.Elflujodeairealacapuchaseregulaconlaválvula.Desde
la válvula reguladora el aire circula por una manguera provista de
válvuladeretenciónyporunapiezadeacoplamiento,hastalacareta.
La válvula de control está equipada con un silbato de aviso que se
activa si la cantidad de aire desciende por debajo del caudal de
aire mínimo permitido. El caudal de aire mínimo permitido por el
fabricante es de 120l/min.
1.3 Aire de respiración
De acuerdo con la norma EN12021:2014, para que el aire sea
respirable debe cumplir los siguientes requisitos de pureza:
•lassustanciascontaminantesdeberánmantenerseaunmínimo
y en ningún caso deberán exceder del valor límite higiénico.
•el contenido de aceite mineral deberá ser lo suficientemente
bajo como para que su olor no se aprecie en el aire. (El límite de
percepciónolfativaesdeunos0,3mg/m3).
•elpuntoderocíodelairedeberáserlosuficientementebajocomo
para evitar que se forme escarcha en el interior del equipo.
En caso de que haya duda de que las exigencias de más atrás se
hayan cumplido, puede conectarse un filtro de aire comprimido
como el Sundström tipo SR 99. Fig. 10. El filtro SR 99 de aire
comprimido consta de un separador preliminar y un filtro principal.
Elfiltroprincipalconstadeunaseccióndefiltrodegas(claseA3
según EN 141:1990) con aproximadamente 500 gramos de carbono
activado, rodeado por dos filtros de partículas (clase P3 según EN
143:1990). La capacidad de separación es de 100-150 gramos
deaceite.Vertambiénloindicadosobreelairederespiraciónen
