The Coilhose CoBlo is a combination quick coupling and blow gun in one. The unit is convenient for metalworking or woodworking operations, which often produce shavings or sawdust making it difficult to view the work surface. A quick burst or two from the CoBlo allows the operator to get back to work quickly without having to disconnect the tool, connect a dedicated blowgun, and then reconnect the tool. The CoBlo can be used with an air tool connected or disconnected and is currently available in 1/4" industrial, automotive, and ARO interchanges.
