Isabella ★★★★★

Swapped out my old single-stage for this two-stage direct-drive and the difference in pull-down time is obvious—that 3 cfm free air clears the chamber fast. The 1/2 hp motor hums along quietly and hasn’t missed a beat on a dozen pours.

Ryan ★★★★★

I’ve been using this pump for a few weeks in my casting setup and the 1/2 hp motor handles the load without any strain. It pulls down to a deep vacuum in under a minute, which has noticeably improved the detail in my wax burnout results.

Andrew Z. ★★★★★

The two-stage system pulls vacuum fast enough that my flask degassed before I even finished mixing the next batch, and the 1/2 hp motor runs surprisingly quiet for a unit this size. It's held steady pressure through two full casting sessions without a hiccup, which is exactly what I needed.
