The CMRD40 Dual RD40 CBRN/NBC Mask is a full-face mask designed to provide respiratory and facial protection in situations involving potential exposure to certain chemical, biological and radiological agents, gases, vapours, aerosols and particles, always depending on the classification of the filters installed and their respective limitations of use.

Made from flexible liquid silicone, the mask is designed to provide a comfortable facial fit, stability during use and an appropriate seal.

The Dual RD40 configuration incorporates two 40 mm threaded connections, allowing the simultaneous use of two compatible RD40 filters. This arrangement helps distribute the weight of the filters across both sides of the mask and may contribute to a more balanced configuration during use.

The panoramic polycarbonate visor provides a wide field of vision, while the integrated speech diaphragm facilitates communication while the mask is being worn.

The product is supplied with two RD40 filters, according to the selected configuration.

Main Features

Full-face mask

Provides complete facial coverage, combining respiratory protection with eye and facial protection.

Dual RD40 System

Equipped with two 40 mm RD40 connections for the simultaneous installation of two compatible respiratory filters.

EN 148-1 Compatibility

According to the information provided, the connections are compatible with filters using the standardised RD40 thread in accordance with EN 148-1.

Liquid Silicone Construction

The facial contact area uses flexible liquid silicone, designed to adapt to the contours of the face while providing comfort and mechanical resistance.

Panoramic Visor

The polycarbonate (PC) visor is designed to provide a wide field of vision and good peripheral visibility.

Anti-Fog System

According to the specifications provided, the visor features properties designed to reduce condensation during use.

Mechanical Resistance of the Visor

According to the information provided, the lens offers high impact resistance and scratch-resistant properties.

Integrated Speech Diaphragm

Component designed to improve voice transmission and speech intelligibility while the mask remains in place.

Full Head Harness

Adjustable system designed to distribute pressure across different areas of the head and provide greater stability.

Compatibility with Spectacle System

According to the information provided, the mask supports a compatible system for prescription lenses.

Bilateral Filter Distribution

Installing one filter on each side helps distribute the weight of the filtration system more evenly.

Dual Filtration System

The CMRD40 features two lateral RD40 connections, allowing two respiratory filters to be used simultaneously.

This configuration distributes the filter elements across both sides of the mask and avoids concentrating all the filter weight in a single location.

The protection capability of the system depends directly on the filters installed. The mask should only be used with compatible filters suitable for the identified contaminant or hazard.

Filter Compatibility

Depending on the configuration and specifications of each filter, the mask can be used with compatible 40 mm RD40 filters, including categories such as:

P3
Filters designed to provide protection against certain solid and liquid particles.

ABEK
Filters designed for certain categories of organic, inorganic and acid gases and vapours, as well as ammonia and its derivatives, depending on the respective classification.

ABEK-P3
Combined filters for certain categories of gases and vapours together with particle filtration.

CBRN/NBC
Filters specifically classified by their manufacturer for certain chemical, biological, radiological or NBC/CBRN hazards.

The RD40 designation refers to the connection type and does not, by itself, determine the protection capacity or classification of the filter.

Construction

The mask incorporates the following main components:

full-face liquid silicone structure;

panoramic polycarbonate visor;

two lateral RD40 connections;

internal oronasal mask;

respiratory valve system;

speech transmission diaphragm;

adjustable head harness.

The structure is designed to combine facial protection, visibility, stability and compatibility with different RD40 respiratory filters.

Vision System

The mask uses a panoramic polycarbonate (PC) visor designed to provide an extended field of vision.

According to the information provided, it offers:

wide field of vision;

good peripheral visibility;

high transparency;

anti-fog properties;

scratch resistance;

high mechanical resistance.

Communication System

The integrated speech diaphragm is designed to improve voice transmission through the mask.

This feature facilitates communication between users during operations, emergency situations and other environments where respiratory protection must be maintained during verbal communication.
