3M 4251 (A1P2) Respirator A1P2D Organic Vapour/Dust

The 3M 4251 respirator uses innovative technology to provide integral construction gas and vapour respirators.

Suitable for many applications including conventional paints, chemical manufacture and handling, paint and varnish manufacture etc. Provides protection against organic vapours up to 10 times WEL or 1000ppm, whichever is lower and 10 times WEL for particulates.

The 3M 4251 respirator uses twin inhalation valves to reduce breathing resistance, together with bonded carbon filters, which do not require granule containers.

This is complemented with a parabolic valve which further reduces breathing resistance whilst preventing heat build-up.

The single piece integral construction also avoids operator assembly errors and allows a respirator to be designated to a specific area, making a respirator programme easier to manage.

The 3M 4251 respirator meets with European Standard EN405:2002 for valved filtering half-mask respirators for gases, or gases and particulate combinations.
