CO / NO filter cartridge - X-plore 40mm A2B2E2K2 Hg NO CO20 P3 filter

CO / NO filter cartridges

Carbon monoxide (CO) and nitrogen monoxide (NO) are gases that are extremely difficult to filter because they tend to take the place of oxygen in the air. In most cases, in presence of these gases, a supplied air respirator system (like self-contained breathing apparatus or supplied air respirators) is to be preferred.

There are 2 types of CO / NO filters mainly dedicated to evacuation in case of danger - A1B2E2K1Hg CO20 NO P3 or A2B2E2K2Hg CO20 NO P3 - all with the same level of CO / NO filtration. The only difference being a less powerful filtration for organic vapors (A) and ammonia (K).

This type of filter cartridge is intended for CO / NO filtration, the A1B2E2K1Hg CO20 NO P3 filter is recommended, kept in stock, and is a slightly lighter and less expensive.

CO / NO filters technical specifications

• Operating principle: gases and vapors are removed from the ambient air by adsorption (activated carbon), water vapor is removed thanks to the impregnated activated carbon (desiccator) and the CO is transformed into CO2 and heat using the catalyst of CO (Hopkalite), particles are captured by the micro-fiber filter
• Rd40 DIN connection: Standard Rd40 threaded connection (Rd 40mm x 1/7 ") according to EN 148 - 1
• Materials:
  - Housing: aluminum, with interior treatment
  - Absorbent agent: activated carbon, hopkalite
  - Particle filter: glass microfibers, cellulose fibers, additives
  - Stoppers: screw-on or rubber
• Weight: Approx 435 grams
