Similar in concept as the SYS-Vac, create a small capacity (1 or 1.5 gal) compressor that conforms to systainer dimensions (i.e. Sys2 or Sys3). Compressor controls and hose connector positioned on the front panel and electrical outlet on the back. Like the Sys Vac such a compressor would fit on the CT vacs and Sys Roll the making it highly portable and mobile for onsite work. Anything that can save trips to and from the van would be highly appreciate and valued.
