The 9920 half-mask airline respirator from Allegro offers a comfortable silicone facepiece. Low pressure continuous airflow gives continuous protection from airborne chemicals. Intended to be used with air supply provided by an ambient air pump. Popular with spray foam installers and welding applications. Low profile design fits under many welding helmets.

Durable silicone rubber is hypoallergenic, resistant to many chemicals, and remains soft even after years of use. Standard double elastic suspension straps keep the mask comfortably in place.

A 90 degree elbow allows the hose to be directed over the shoulder and out of the way. The hose itself is made of a lightweight corrugated material for flexibility and greater comfort. The hose may be switched to either side of the mask - however it works best for you.

An OBAC quick-connect plug has a wide diameter opening and minimal air restriction. Great when you are using a low power ambient air pump. Nylon waist belt is included.

NIOSH Approval No. TC-19C-355
Per NIOSH regulations, only the manufacturers (Allegro) approved airline hose may be used up to the 'point of attachment'.

    Is this 1/2 mask respirator rated to be used in an IDLH attmoshere or in an application that has the potentional of the O2 level droping below the normal 21% oxygen level.

    I have an application where we will be required to perform work in an area that will be concedered a confine space and the oxygen level could drop below 19%. Is this respirator rated by NIOS for this application.

    Thanks

      <p>The item you've listed is only for the mask portion and you will need the whole set up in order to use it in a IDLH atmosphere. Please see the link below for the full set up.<br /><br /> <a href="https://www.pksafety.com/allegro-1-worker-half-mask.html">https://www.pksafety.com/allegro-1-worker-half-mask.html </a><br /><br /> Just the respirator alone will not suffice because there is no fresh air source being pumped through the hose to the respirator. So, a pump (to be installed in an ambient air environment) is needed to complete it. If you have any further questions, please contact us at 1-800-829-9580</p>

    Does this respirator work with gas cylinders or does it have to have an air pump? I'm interested in using this with a backpack of sorts so I can be more mobile with it.

      This system uses an air pump that requires AC power. There is a solution on the market for your needs, it's called SCBA and it's what fire fighters use. We have the equipment listed on our website, please search for SCBA
