This family of items from Air Systems International centers around the BB60 Series Breather Box®, a portable Grade-D breathing air filtration system engineered to deliver clean, monitored air for up to four respirator users simultaneously. Offering an intermediate, high-capacity flow rate of 60 CFM filtration, this family includes specialized filtration units for IDLH (Immediately Dangerous to Life or Health) environments, mobile cylinder carts, replacement filter elements, and essential system calibration accessories.
Below is a breakdown of the items in this family, structured for quick navigation.
??? Filtration Systems (Breather Box® & Carts)
Model SKU Item Name & Category Description Key Features
BB60-COAA Auto-Air™ Breather Box® (Standard) Fully automatic reserve air system designed for mid-sized crews in 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. Outfitted with a 4-outlet manifold.
BB60COAAP Auto-Air™ Breather Box® (Intrinsically Safe) Fully pneumatic, intrinsically safe variant of the 60 CFM system tailored for highly volatile, explosive industrial settings. Employs a certified intrinsically safe CO monitor (9V DC only). Approved for hazardous areas where spark risks must be eliminated.
BB60HTAA Auto-Air™ Cylinder Cart (Electric Reserve) A mobile cylinder cart system combining a 60 CFM Grade-D filtration box with an electric backup reserve and dual cylinder storage. Designed for rapid transit across refineries and industrial complexes. Accommodates two backup cylinders and features integrated alarms.
BB60HTAAP Auto-Air™ Cylinder Cart (Pneumatic/Safe) A mobile intrinsically safe cylinder cart combining the BB60COAAP filtration box with a fully pneumatic reserve system. Built on a heavy-duty cart frame for hazardous environments. Uses zero electric components to eliminate potential spark ignition risks.
?? Replacement Filters & Maintenance Accessories
To keep the 60 CFM Breather Box units operating at peak 99.99% efficiency at 0.01 microns, the system utilizes a proprietary 3-stage filtration structure specifically sized for the 60 CFM housing.
• BB60-A (Stage 1 Filter Element): A high-efficiency particulate and bulk liquid separation filter. It removes bulk water, oils, and coarse debris to prevent clogging downstream.
• BB60-C (Stage 2 Filter Element): A fine oil coalescing filter element. Captures ultra-fine particulates and oil mists down to 0.01 microns.
• BB60-D (Stage 3 Filter Element): An activated charcoal adsorber filter. It eliminates unpleasant organic vapors, toxic odors, and industrial tastes from the breathing line.
• BB60-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.
