This family of items from Air Systems International revolves around the BB100 Series Breather Box®, a portable Grade-D breathing air filtration system engineered to deliver clean, monitored air for up to four or more respirator users simultaneously. With a high-capacity flow rate of 100 CFM filtration (123 CFM flow capacity), this family includes high-performance filtration systems tailored for IDLH (Immediately Dangerous to Life or Health) environments, mobile cylinder carts, replacement filter elements, and vital system calibration accessories.
Below is a breakdown of the items in this family, categorized by system type and maintenance accessories.
??? Filtration Systems (Breather Box® & Carts)
Model SKU Item Name & Category Description Key Features
BB100-COAA Auto-Air™ Breather Box® (Standard) Fully automatic reserve air system designed for IDLH work environments. Operates on standard electric/battery power. Automatically switches to reserve air cylinders if primary compressor pressure drops below 60 PSI or if electrical power fails. 4-outlet manifold.
BB100COAAP Auto-Air™ Breather Box® (Intrinsically Safe) Fully pneumatic, intrinsically safe variant of the COAA system tailored for highly volatile, explosive industrial settings. Employs a certified intrinsically safe CO monitor (9V DC only). CSA approved for Class I, Division 1, Groups C and D environments.
BB100HTAA Auto-Air™ Cylinder Cart (Electric Reserve) A mobile cylinder cart system combining a 100 CFM Grade-D filtration box with an electric backup reserve and dual cylinder storage. Holds two 60 or 87 cubic feet air cylinders. Running on 115 VAC power with integrated alarms. Ideal for rapid transit across refineries and buildings.
BB100HTAAP Auto-Air™ Cylinder Cart (Pneumatic/Safe) A mobile intrinsically safe cylinder cart combining the BB100COAAP filtration box with a fully pneumatic reserve system. Built on the dual-air cart frame for mobile hazardous environments. Zero electric components to eliminate potential spark ignition risks.
To keep the 100 CFM Breather Box units operating at peak 99.99% efficiency at 0.01 microns, the system utilizes a proprietary 3-stage filtration structure.
• BB100-A (Stage 1 Filter Element): A high-efficiency particulate and bulk liquid separation filter. It removes 95% of bulk water, oils, and coarse debris down to 5 microns to prevent clogging downstream.
• BB100-C (Stage 2 Filter Element): A fine oil coalescing filter element. Captures 99.9998% of ultra-fine particulates, oil mists, and atomized droplets down to 0.01 microns.
• BB100-D (Stage 3 Filter Element): An activated charcoal adsorber filter. It eliminates unpleasant organic vapors, toxic odors, and industrial tastes from the breathing line.
• BB100-FK (Replacement Filter Kit): A comprehensive maintenance kit containing one of each filter element (A, C, and D). Purchasing the full kit simplifies scheduled filter changes to preserve system compliance.
• BBK-20 (CO Monitor Calibration Kit): A standard safety testing kit featuring a 17-liter disposable gas cylinder loaded with 20 ppm Carbon Monoxide. Essential for mandatory monthly sensor calibration to guarantee true OSHA and CSA breathing air metrics.
