Breather Box Systems

An essential part of every complete blast operation is properly selected and well-maintained respiratory safety equipment capable of delivering “Grade D” breathing air to the operator.  When using compressor technology that is driven by internal combustion engines that may be out of service, or in situations where a compressor’s air intake is near exhaust or other hazardous gas emissions, it could be possible for Carbon Monoxide or other toxic vapors to make their way into the compressed air supply.  If there is ever concern that this type of contamination exists, we recommend that a Carbon Monoxide monitor be used to ensure that trace amounts of harmful gases are detected and prevented.  In the section below we have listed some of the industry’s most proven Breather Box systems.  These units are designed to thoroughly clean the incoming air supply, test for carbon monoxide contamination and then properly regulate the outgoing air to the operator’s hood or mask.There are numerous ways to properly set up an efficient (and compliant) breathing air system so please don’t hesitate to contact us with any questions you might have.  For your reference, we have attached a thorough explanation of what constitutes “Grade D” breathing air in a blasting application.  This information is also featured in our technical library section listed at the top of the page.

 

“Breathing Air Quality In An Abrasive Blasting Context”

Air Systems International Breather Box®

Air Systems International is the industry leader in air quality equipment and related systems.  Their flagship product, theBreather Box®, is one of the most commonly used and battle tested air quality systems on the market.  This unit and all its components come packaged in a heavy-duty Pelican™ case making it perfect for the toughest field applications.  When hooked up to your compressed air source, incoming air passes through a 3-stage filter, removing all traces of contamination.  After the air is clean, the box’s internal regulator sets the air at your desired pressure and a sample of that outgoing air is taken and processes by the CO monitor packaged within the unit.  Should the Carbon Monoxide levels ever exceed the allowable 20 ppm, the unit’s audible alarm (rated at 95 dBA) will sound and a visual light on the face of the case will light up.The sensing equipment housed within the case runs off standard 115 VAC power when available.  In remote locations where power sources are limited, two 9 VDC batteries installed within the monitor will power the unit with complete functionality.  Upgraded high intensity audible and visual alarms are also available for this unit. The Breather Box® comes in 30, 50, 75, 100 and 150 CFM configurations, each with their own available number of outlets.  An optional CO/O₂ monitor is available with most units.
