DPi C21 Tactical CBRN Respirator
The C21 by DPi is a modern tactical CBRN respirator designed to deliver reliable respiratory protection for law enforcement, public order policing, corrections, and emergency services operating in hazardous environments.
Built on the same advanced platform as DPI’s military respirators, the C21 combines high protection performance, excellent comfort, and simplified operation, making it well suited to agencies that require dependable CBRN capability without unnecessary system complexity.
Designed for Operational Simplicity and Reliability
From the outset, the C21 was engineered for users who require effective protection during chemical exposure, riot control, and HazMat incidents, while operating in controlled or semi controlled environments.
As a result, the respirator delivers the same advanced ergonomics, visibility, and breathing performance as higher-end tactical systems, while maintaining a simpler architecture that supports
Faster training and familiarisation
Reduced maintenance burden
Lower whole of life cost
Consequently, the C21 is particularly well suited to policing and emergency response organisations.
Certified CBRN Protection
The C21 provides certified protection against a wide range of threats, including
Chemical warfare agents (CWA)
Toxic industrial chemicals (TIC)
Biological aerosols and particulates
Riot control agents such as CS, CN, and OC
The respirator is compatible with NATO-standard 40 mm threaded filters, allowing agencies to integrate existing filter inventories and simplify logistics.
In addition, the C21 is certified to EN 136:1998 Class 3, ensuring suitability for demanding operational environments.
C2 and C3 Riot Control Filters
In addition to DIRIN NBC canisters, the C21 tactical CBRN respirator is fully compatible with DPI C2 and C3 riot control filters, providing agencies with flexible respiratory protection options for public order and custodial operations.
C2 Riot Control Filter
The C2 filter is designed for short duration public order and crowd control deployments, delivering reliable protection against common riot control agents while maintaining low breathing resistance.
Key characteristics include
Protection against CS, CN, and OC riot control agents;
Lightweight design for high mobility operations;
Reduced breathing resistance during high exertion; and
Ideal for rapid response policing and short-duration deployments.
C3 Riot Control Filter
By contrast, the C3 filter is engineered for extended duration riot control and custodial operations, offering increased sorbent capacity and longer service life.
Operational benefits include
Enhanced protection against riot control agents and industrial irritants;
Longer breakthrough times compared to C2 filters;
Suitable for prolonged public order incidents and corrections use; and
Optimised for sustained wear during extended operations.
Flexible Filter Selection for Operational Needs
As a result, agencies can select the appropriate filter based on:
Threat profile
Duration of deployment
Environmental conditions
Operational tempo
This flexibility allows the C21 to function as a scalable riot respirator and gas mask system, supporting both short duration response and prolonged public order or custodial operations.
Modular Accessories & Configuration Options
Furthermore, the C21 supports a range of accessories that allow agencies to tailor the respirator to their operational needs.
Available accessories include
Communication voice emitters and interfaces
Hydration system compatibility
Visor outserts for sunlight, impact, and laser protection
Carry bags and storage solutions
Vision correction inserts
This modular approach allows the C21 to be configured as a riot respirator, emergency CBRN respirator, or HazMat response mask, depending on mission profile.
Ideal Applications
Accordingly, the C21 is ideally suited for
Public order and riot control policing;
Corrections and custodial environments;
Emergency services and HazMat response;
Court and secure facility operations; and
Training and preparedness programs.
Alternately where high-risk CBRN threats are a reality, the M21 CBRN Respirator offers the same quality and protection with an automated valve shutoff to assist in canister changes.
Supported in Australia by Tactical Solutions
Tactical Solutions provides Australian support for the C21 tactical CBRN respirator and DIRIN canister system, working closely with police, corrections, and emergency services to ensure effective deployment and sustainment.
Support includes:
Respirator and filter selection advice
Configuration and accessory support
Training and familiarisation
Lifecycle and sustainment planning
As a result, agencies can deploy the C21 as a complete, supported respiratory protection capability, not just a standalone gas mask.
