MSA Advantage 3121 Full Face Respirator, medium

This particular version of the Advantage 3000 comes in a size medium, with an Advantage harness and a single thread connection. 

Please Note: Filters are not included with this product.

The MSA Advantage 3100, part of the Advantage 3000 series, provides breathing protection through a range of full and half masks.  The range also provides comfort and quality and can be used with filters and powered air-purifying devices.  The masks have been designed based on the strong Voice of Customers analysis and have mirrored these results in the development of the full face and half masks.

Excellent Wearer Comfort

To provide protection and comfort the Advantage 3100 comes with a soft sealing line made of hypo allergenic silicone which provides a pressure free and safe fit.  Another feature is the innovative head harness which has the benefit of giving a perfect piece-to-face fit.  It can be quickly and easily put on and taken off without having the problem of painful hair pulling.  This MSA full face respirator is also simple to adjust when worn.  

Optimal Protection

The MSA full face respirator from the Advantage 3000 series is available in two different versions and in three sizes, allowing users to find the perfect fit for their faces and meets all requirements concerning respiratory protective equipment.  It adapts perfectly to different face shapes.    A panoramic view lens is another feature of the Advantage 3100 and gives the user a clear, undisturbed field of view.  The grey-blue colour of this large, optically corrected lens also gives the mask an aesthetic appearance.  

Cost Effectiveness

The Advantage 3000 series, available in two different versions (twin and single connections) reduces test and training costs.  The MSA Advantage 3100 in particular comes with an EN 148 standard thread filter connection, whereas the Advantage 3200 comes with a bayonet connection.
