APA and RD40 adaptors allow to use Aria 19 Mask as a device for personal protection in two different configurations:

  1. In combination with the Aria Protection Adaptor (APA) and a P3 filter. This filter protects against mist, aerosols, particles, fumes and dust. For more info on filter, see the P3 filter technical sheet.
  2. In combination with the Aria Protection Adaptor (APA), the RD40 40-22 mm adaptor and an HEPA filter (standard connection ISO 5356-1). This kind of filter protects against airborne and liquid-borne microbial pathogens. For more info on filter, see the HEPA filter technical sheet.

APA and RD40 specific features:

Easy use: 

APA and RD40 adaptors are easy to assembly on the Aria 19 mask, also when you are wearing it.

MATERIALS: Polycarbonate.


APA: 27 g
RD40-22: 18 g


Limitations for the use

Do not use in areas where the oxygen concentration is lower than 17% in volume nor in the presence of gases and vapours.

Breathing and no fogging behaviour

The user breaths in potentially contaminated air, drawing it in from only one inlet through the filter body, and through a one-way only valve. The filter purifies the air according to its certified properties and characteristics. The safe, breathable air then moves onto the visor, pushed onto it from a deflector placed in the topside of the mask. This action prevents fogging. The air then flows through one-way valves in the orinasal pocket where the user breaths in. Once the user exhales, the two one-way valves in the orinasal pocket, prevent the air’s return in the ocular part of the mask. The air will not be able to be drawn back up due to the one-way valve placed on the filter adaptor. The only way the air will be forced to go, is through the one-way valve of the chin, to the outside of the mask.
