HEPA acid gases combined cartridge compatible with TR-600 Versaflo

3M HEPA combined filter/cartridge for protection from acid gases and solid particles.

Compatible with 3M TR-600 Versaflo powered air-purifying respirator (PAPR). Sold by unit. Please allow 2 to 3 weeks for delivery.

3M manufacturer’s code: TR-6320N

TR-600 combined cartridges don’t require the use of a filter cover like their prior model. Even without the filter cover, this model of cartridge is NIOSH approved. It is, however, recommended to use the cover filter RVTR6300FCto to help protect the filter/cartridge from physical damage and liquid spills. The RVTR6300FC filter cover is also used to hold the RVTR6600 pre-filter orRVTR662 spark arrestor in place in order to extend the service life of the cartridge.

This type of cartridge has two indissolubly linked parts, that is, a HEPA filter, which protects one from airborne particles, and an active charcoal part, which protects one from gases and vapors. The filter is certified HEPA, which means it protects from 99,97% of solid, liquid, oil-based and non-oil based particles in the air. As for the active charcoal part, it is the most efficient and cost-efficient method of filtering airborne contaminants on the market. 3M RVTR6320N cartridges have been designed to protect one from acid gases such as chlorine dioxide (ClO₂), sulfur dioxide (SO₂), hydrogen fluoride (HF), hydrochloric acid (HCl) and many others. The RVTR6320N cartridges for acid gases can protect one from hydrogen sulfide (H₂S) for a limited time. Without the right equipment, H₂S is extremely hazardous. These cartridges are meant to protect one in case of emergency evacuation due to a release of hydrogen sulfide. One must, of course, throw away the cartridges exposed to that gas.

This 3M combined HEPA cartridge, designed for Versaflo TR‑600 powered air‑purifying respirators, offers dual protection: high‑efficiency HEPA filtration and acid gas neutralization. It captures 99.97% of fine particles while effectively filtering common acid gases found in industrial settings.

Its operation is based on advanced filtration technology that ensures constant airflow and optimal breathing comfort. Robust and reliable, it meets the requirements of chemical, pharmaceutical, manufacturing, and processing sectors.

Technical Features – Combined HEPA Cartridge for Acid Gases 3M Versaflo TR‑600

This type of cartridge is ideal for chemical manufacturing, glass etching, paper manufacturing and laboratory work. The HEPA filter of this combined cartridge also protects from solid particles loosen in the air and aerosol liquid particles. 

It protects from oil-based particles, radioactive particles (uranium, plutonium), heavy metal particles (lead, cadmium, arsenic), and carcinogenic particles (4,4’methylenedianiline (MDA)). HEPA filters protect one from silica, the second main cause of chronic respiratory problems after asbestos. It is also highly advised to stay away from environments that exceed the limits set by the competent authorities. The choice of facepiece is important, since it has a direct influence on the limits of your equipment.

CAUTION: RVTR6320N cartridges don’t protect one from carbon monoxide (CO) and carbon dioxide (CO₂). If one has to work in an environment that may contain those two gases, one has to find another way to protect himself.

Biological particles:

This type of cartridge helps prevent the inhalation of certain airborne biological particles like mold, Bacillus anthracis (Anthrax), Mycobacterium tuberculosis (Tubercle bacillus Koch) the main causative agent of tuberculosis, pandemic flues (H5N1, H1N1), etc. However, it cannot eliminate the risk of contracting infection, illness or disease. Of course, whenever one has to protect himself only from biological particles, one should definitely opt for something else than this equipment. HEPA cartridges are by design made for workers who must protect themselves from biological particles on top of being protected from gases, vapors and airborne particles.

Do not use for:

One should never use a respirator of any kind whenever concentrations of gases and vapors exceed the admissible limit. Avoid sandblasting and oxygen deprived environments (an atmosphere with less than 19,5 % oxygen). It is recommended to avoid environments that exceed the limits of your equipment with respect to the permissible exposure limit set by the CNESST or any other government regulation applicable.

Powered Air Respirator Installation – 3M TR‑600 Combined HEPA Cartridge

Installing the combined HEPA cartridge on the 3M Versaflo TR‑600 powered air respirator is simple and quick. Just insert the cartridge into the unit until you hear a firm click, ensuring a secure connection. This intuitive system allows fast replacement without interrupting respiratory protection.

Respiratory Protection Maintenance – TR‑600 Combined HEPA Cartridge

Studies have shown that in case of contaminant mixture, all the vapors are absorbed simultaneously by the granulated charcoal inside the cartridges. One must take into account the presence of a contaminant mixture, since the most volatile solvent will saturate the cartridge. The cartridge service life and one’s degree of protection will then depend on the concentration and the nature of the contaminants in the air.

Since this is a disposable product, there is no maintenance. The manufacturer’s limitations must be followed. One may store its cartridges in an airtight bag or container, since even not in use, the cartridge absorbs whatever contaminant there may be in the air.

In theory, one should use the RVTR971 airflow indicator to assess the state of the equipment. However, the motor/blower is equipped with a system that alerts you in case the filter is soon to be saturated; one must thus change the cartridge. Please note that that system prevents only the full saturation of the HEPA filter part of the cartridge. Whenever one may smell or taste the contaminant from which he protects oneself from, the charcoal part is saturated; one must thus change both cartridges again.

FAQ – 3M Versaflo TR‑600 Combined HEPA Cartridge for Acid Gases

Is the TR‑600 combined HEPA cartridge compatible with all 3M respirators?

No, it is exclusively compatible with 3M Versaflo TR‑600 powered air respirators to ensure optimal performance.

Does this cartridge protect only against particles?

No, it provides dual protection: HEPA filtration of fine particles and neutralization of acid gases.

When should a TR‑600 combined HEPA cartridge be replaced?

Replacement depends on contaminant concentration and exposure time. It must follow the recommendations of the internal safety program.
