K1668-2 - Lincoln Mobiflex 100 Exhaust Extension Hose 16ft

Technical Overview of the Lincoln Electric K1668-2

The Lincoln Electric K1668-2 is a specialized Exhaust or Extension Hose Set designed specifically for the Mobiflex 100-NF fume extraction system. Engineered to meet the rigorous demands of industrial environments, this component serves a critical role in managing welding fumes and maintaining air quality standards within the workspace. The hose features a nominal diameter of 5.75 inches (146 mm), ensuring optimal airflow characteristics that match the blower specifications of the Mobiflex unit, thereby preventing backpressure issues that could compromise extraction efficiency.

One of the defining technical characteristics of the K1668-2 is its robust construction. The hose body is reinforced with external steel rings. These rings serve a dual purpose: they provide structural integrity to prevent the hose from collapsing under negative pressure or crushing under external physical stress, and they act as wear strips when the hose is dragged across concrete floors. This design significantly extends the service life of the component compared to non-reinforced ducting solutions. The total length of the hose is 16.4 feet (5 meters), providing substantial reach for various configuration requirements.

Functionally, the K1668-2 is versatile. It is primarily specified as an exhaust hose for the Mobiflex 100-NF, directing filtered air away from the immediate vicinity of the operator. Alternatively, it can be utilized as an extension segment for the K1668-1 hose, effectively doubling the reach of the extraction intake for applications where the base unit cannot be positioned close to the arc. The kit is supplied complete with two heavy-duty clamps, ensuring a secure, leak-free connection to the filtration unit or connecting couplers. This product is an essential accessory for facilities prioritizing compliant and effective fume management.
