MSA Advantage 420

With its moldy UniBond face shield, AnthroCurve™ face seal, MSA advantage 420 Respirator is the best choice for respiratory protection.


Advantage 420 Half Mask Respirator 

The innovative Advantage 400 half mask stands out due to exceptional comfort and sophisticated design. The patent pending single loop head harness is unique to the market. It grants the user an intuitional operation and offers high comfort and flexibility. The drop-down option allows the user to remove the mask from the face without removing his other safety equipment (like helmet, ear muffs or spectacles).

The respirator can be worn along the chest until the next use. Lock-down permits to set the harness to the proper fit. It can be then reused without any further adjustments. The one-piece MultiFlex nose cup is made of soft and smooth co-molded silicone and rigid plastic. This unique combination gives the face piece great durability and extraordinary stability when worn, without compromising comfort.

The Advantage 400 is either available with single thread EN 148-1 connection (Advantage 410) or with twin bayonet MSA connection (MSA Advantage 420 Half Mask Respirator). For both versions MSA offers a wide range of different filters, suitable for all applications.

With its UniBond over-mold facepiece, AnthroCurve™ face seal, and low profile design, MSA Advantage 420 Half Mask Respirator is the superior option for respiratory protection. The over-mold facepiece and face seal ensure the unit provides an excellent fit and comfort to the wearer. The unique yoke and harness design (patent pending) allows a user to easily don and doff the state-of-the-art respirator while maintaining a customized fit. Other features include a ComforTop headband, a built-in moisture release chin cup hole, and the extra-wide head and neck straps.
