The Ai AccuTemp 3.2 cu ft vacuum ovens are UL/CSA certified, this certification is required by many municipalities, and it also provides a higher standard of equipment safety and lifespan. Also come standard is the secondary over-temp protection dial, stainless steel tubing, stainless steel vacuum & vent valve, oil-filled vacuum gauge, and two year warranty. With our new internal shelf heating technology, each shelf in these ovens has its own heater, in-shelf temperature sensor and temperature controller, together with great thermal-conductive aluminum and our new low proportional controller technologies, the result is perfect uniformity, accurate temperature, super-fast heating rates, minimum heat loss/exterior temperature and very low power consumption.

Every one of our vacuum ovens goes through a 2-time 24-hour vacuum leak test, and is 100% quality controlled.

Important! Never leave your oven unattended while operating.


  • KF25 inlet filter keeps your oven clean at all time (included with oven purchase)
  • All stainless steel internal tubing provides higher ultimate vacuum, holds vacuum 10 times longer, and require minimum maintenance.
  • Oil-filled mechanical vacuum gauge provides more accurate reading, longer gauge life and minimizes shipping damage.
  • All stainless steel vacuum and vent valves gives you cleaner connection, more accurate control and long term durability.
  • Three alumimum heating shelves with individual in-shelf temperature sensor, temperature controller and heater.
  • Dual layer observation window with 5/8" tempered safety glass.
  • 3rd gen low proportional gain temperature controllers keep your oven temperature within +/- 1°F accuracy, in either °F or °C.
  • Easy-to-clean stainless steel interior for exceptional durability and ease of maintenance.
  • A vacuum environment lowers the boiling point (great for processing heat sensitive materials) and reduces drying time for materials like paste or powder which cannot otherwise be easily dried.
  • Built-in wheels for ultra portability
  • Built-in alarm alerts you when oven has been shut down by safety circuitry due to out of range temperature.
  • For improved temperature tracking, run the auto-tune procedure as outlined in the manual.
  • Best choice for the curing and converting of oil extracts. With deep vacuum level, they can operate at temperatures which allow the degassing/purging process to occur rapidly, thus increase productivity and allow for the production of superior quality products with minimal processing time.
  • All ovens shipped from New Jersey or Nevada for quick delivery, and come with one year warranty and lifetime US-based parts and service support.
