Sundstrom Gas Filter A1 (SR217)

Organic vapour filter class A1 (regular capacity).

Used in conjunction with Sundström SR100,SR200 and SR500 respirators.



Plastic polypropylene. No metal parts.


Used against organic gas and vapour with a boiling point above +65°C,such as solvents. The filter fits into the filter attachment of Sundström's half and full face masks. An SR510 particle filter can be snapped onto the front of the filter. 


— Largest diameter: 106 mm
— Thickness: 28 mm


113 g


The filter contains 70 g of activated carbon.

Adsorption capacity

In tests with 1,000 ppm carbon tetrachloride at 30 l/min, the filter lasts for 90-110 minutes (standards requirements: >80 min) The filter absorbs approximately 20-25 g carbon tetrachloride (standards requirements: >15.4 g).

Pressure drop

— At 30 l/min: 25-30 Pa (standards requrement: <100 Pa)
— At 95 l/min: 120-140 Pa (standards requirement: <400 Pa)


Store at room temperature in clean, dry place. If seal has been broken, store away from contaminants in an air-tight container. Shelf life is 5 years if seal is unbroken. Expiry date printed on filter.
