Can the SC-EB gun feed from the case rather then carry the bottles around?
No, the SC-EB cannot feed from the case. The SC-EB has two Nalgene® bottles that are removed from the case during use and either handheld or hooked on a belt. Only compressed air travels through the hose. The spray gun has a short feeder hose that connects to the bottle in use at the time. Each bottle will spray for about 15 minutes. Compare the operation of the SC-1 — Liquid is transported from the internal tank, and air from the air compressor to the spray gun via the “twin-line” hose. One line for air (red), the other for liquid (gray).
