Carbon Monoxide and Breathing Air Filters





A high quality RPB breathing air filter is used in conjunction with a supplied air respirator. The RADEX system filters incoming air from your compressor or air dryer – removing oils, contaminants, smells, and moisture. It’s important that Breathing air filters be replaced every 3 months, because it contains an active charcoal which removes smells and moisture that gets inside the airline, which eventually can transfer molds and/or mildew to the operator’s lungs.

When do you need to replace the actual breathing air filter housing? BlastOne recommend that you replace the entire filter housing every two years as oil, dirt, and other contaminants will build and can find their way into the blast helmet. The system has a regulated pressure valve that can either feed one airline/blast helmet while connecting the other second outlet to the GX4 Carbon Monoxide Gas Monitor.

GX4 Gas Carbon Monoxide Monitor

The RPB GX4 is able to monitor multiple gases including carbon monoxide, oxygen, and hydrogen sulfide (H2S). While monitoring for these gases, the system is simultaneously auto-saving and archiving this information to provide a historical record of events for up to 24 months. Regarding carbon monoxide, the system has a baseline safety alarm set for 10ppm which cannot be altered. A clear tube feeding the prefiltered air offers visibility to any oil or other contaminants that may make their way past the radex filter and could possibly corrupt the Gas Monitor.

Calibration checks can be done by operators in the field through a simple onboard “Wizard” that walks you through the steps. Changing sensors can also be done in-field with the system notifying you 10 days before the sensor will fail, allowing you time to receive a new sensor and install it as simply as changing a standard inkjet cartridge in a printer.

What is Carbon monoxide? And Why is it a killer?

Carbon monoxide is called the Silent killer – its cant be seen, smelt or tasted – a person who gets CO poisoning will begin to loose consciousness, and their respiratory system could begin to shut down involuntary within 2 minutes. One of the most common occurrences for finding CO in a blasting system is when a truck is parked next to the air intake for the compressor.

Monitoring you breathing air for Carbon monoxide is required by law.
