NBM Breathing Air Purification Module By Nano

The nano NBM breathing air purification module restores an aging, expensive, or no-longer-supported breathing air system by replacing only the purifier instead of the entire package. Your existing dryer, filters, and CO monitor stay in service while the NBM takes over the critical purification stage, delivering breathable air that meets OSHA Grade D (US) and CSA Z180.1-13 (Canada) standards. Free standing, compact, and available in six sizes from 30 to 960 SCFM, the NBM is a simple, cost-effective way to get a supplied-air system back up and running.

How it works

1. Compressed air enters the module and passes through the cartridge's integral inlet diffuser, which distributes flow evenly across the purification bed.
2. A mixed bed purifier converts carbon monoxide (CO) and strips odor and taste from the air stream.
3. A built-in 1.0 micron particulate outlet filter captures fines before the air leaves the module, protecting downstream lines and respirators.
4. Purified air exits with a maximum CO content of 5 ppm, ready for supplied-air respirator service.

Key features

• Replaces only the purifier in an existing breathing air system, saving the cost and downtime of a full system replacement
• Multi-stage disposable purification cartridges with integral inlet diffuser, mixed bed CO / odor / taste removal, and 1.0 micron outlet particulate filter
• No power and no controls required; free-standing design installs on the floor or wall mounts
• Easy-to-replace catalyst purifier cartridges for fast, low-cost maintenance
• Optional direct-mount carbon monoxide (CO) monitor available
• Supports OSHA Grade D (US) and CSA Z180.1-13 (Canada) breathing air quality standards

• Confined-space entry, tank cleaning, and maintenance work on multi-user breathing air lines

Frequently asked questions

Do I have to replace my whole breathing air system?
No. The NBM is designed to replace just the purifier stage, so your existing dryer, filtration, and monitoring equipment can stay in place.

What does the NBM remove from compressed air?
The multi-stage cartridge converts carbon monoxide (CO) and removes odor, taste, and particulate down to 1.0 micron, with a maximum outlet CO content of 5 ppm.

Does the NBM need electrical power?
No. The module requires no power and no controls, and it can be floor standing or wall mounted.

How do I size an NBM module?
Rated flows are 30 to 960 SCFM at 100 psig inlet conditions. Select the model whose rated flow meets or exceeds your total breathing air demand; for other operating conditions, contact us for sizing assistance.

How is the NBM maintained?
Maintenance is a simple cartridge replacement using nano NBM service kits. Replace cartridges as required to maintain breathing air quality in accordance with applicable codes and regulations.

The nano NBM breathing air purification module line pairs OSHA Grade D purification with a no-power, cartridge-based design, making it a dependable drop-in purifier for supplied-air systems from 30 to 960 SCFM.
