Ai AT 3.2 cu ft UL/CSA Certified Vacuum Oven

The AT-32 is the first of our four larger vacuum oven models that are built for floor-standing operation. It comes equipped with 4 swivel casters which allow for easy movement, aluminum shelves, a large 3.2 cu ft. stainless steel interior, and a 3/4″ tempered glass window.
Along with the AT-75 and AT-160, the 3.2 cu ft. model comes standard with our new internal shelf heating technology.
New Features
The Ai AT Series comes equipped with the most important features and functions needed to properly purge BHO and other material solvents.
Internal Shelf Heating Technology
Each shelf is equipped with its own heater, temperature sensor, and temperature controller. The result is perfect uniformity, accurate temperature, and rapid heating rates with a minimum amount of heat loss and power consumption.
Accuracy
In addition to our in-shelf heating, the low proportional gain temperature controller keeps your oven’s temperature within +/- 1°F accuracy while in use.
Optimal Vacuum Level
Our ovens greatly reduce drying time of your extracts by maintaining a deep, consistent vacuum level within the chamber – making them the best choice for curing and converting oil extracts.
Increased Productivity, Quality, and Consistency
Our ovens produce deep vacuum level that allow them to operate at the optimal temperature for allowing the purging process to occur rapidly. The result is an increase in the consistent output of superior quality extracts with a minimal processing time.
Dimensions | Oven Chamber = 18″W x 18″D x 18″H divided into 3 vertical sections; Unit = 30.5″W x 24″D x 29″H |
Interior | Stainless steel. |
Safety Features | Built-in circuit breaker and overheat protection with alarm. |
Shelves | Three 4.75″ non-removable aluminum shelves. |
Temp Control | Digital temperature control with timing and alarm. |
Quality Control | All vacuum ovens undergo a 24hr vacuum leak test twice and are 100% quality controlled at either our New Jersey or Nevada facility before shipment. |




Features
- UL certified.
- New 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.
- 4th gen low proportional gain temperature controllers keep your oven temperature accurate
- 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 swivel casters with leveling feet.
- 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 our New Jersey or Nevada location for quick delivery.
- 2-year warranty and lifetime US-based parts and service support.
- Guaranteed US based phone and email assistance within 30 minutes from our engineers.
