Ai AT 0.9 cu ft UL/CSA Certified Vacuum Oven


The UL/CSA Certified AT-09 is our smallest vacuum oven, making it ideal for a small desktop workstation. Along with our AT-19 1.9 cu ft. oven, the 0.9 cubic foot oven is a popular solution for managing lower production volumes.

Oven Features

The new Ai UL/CSA certified Ai AT 0.9 cubic foot vacuum oven comes standard with stainless steel interior vacuum lines, reinforced stainless steel vacuum & vent valves, an oil-filled vacuum gauge, 5 sided heating technology and two year warranty. Four thermally conductive aluminum pan shelves are included, providing excellent temperature uniformity throughout. This oven can hold a maximum of eight shelves for increased productivity. The 3rd generation LCD low proportional gain temperature controller keeps your oven temperature within +/- 1°F accuracy at all times and is able to display in both °F and °C.

New 5-Sided Pad Heating Technology

The AT-09 now comes standard with our new 5-sided pad heating technology. The new heating technology heats up the oven chamber 25% faster than its previous versions and evenly distributes heat from the left, right, back, top, and bottom of the vacuum chamber.

Temperature Uniformity

Our new 5-sided heating system evenly distributes heat from the left, right, back, top, and bottom of the vacuum chamber. The solid aluminum pan shelves maximize the distribution of heat at stable temperatures. This creates even, consistent temperatures inside of the oven chamber, which means better extractions!


The low proportional gain temperature controller keeps your oven’s temperature within +/- 1°F accuracy while in use. All ovens also now come standard with our new, adjustable gas back fill capability with needle valve and vent port.

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.


DimensionsOven Chamber = 12″W x 12″D x 11″H ; Unit = 23.4″W x 17.25″D x 19″H
InteriorEasy to clean stainless steel.
Safety FeaturesBuilt-in circuit breaker and overheat protection with alarm.
Shelves4 solid aluminum shelves included. Holds a maximum of 4 shelves.
Temp ControlDigital temperature control with timing and alarm. Uniformity of +/- 7% of setpoint.
Quality ControlAll vacuum ovens undergo a 24hr vacuum leak test twice and are 100% quality controlled at either our New Jersey or Nevada facility before shipment.


  • UL certified
  • All stainless steel internal tubing and compression fittings 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.
  • New 5 sided pad heating technology and aluminum shelves provide excellent temperature uniformity and faster heating rates (25% faster in our lab test).
  • Adjustable gas back fill capability with needle valve and vent port.
  • 4th gen LCD low proportional gain temperature controllers keep your oven temperature accurate.
  • 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.
  • Dual layer observation window with 1/2″ tempered safety glass.
  • 3″ thermal insulation prevents heat loss and minimizes the enclosure’s outer surface temperature.
  • Easy-to-clean stainless steel interior for exceptional durability and ease of maintenance.
  • Built-in alarm alerts you when oven has been shut down by safety circuitry due to out of range temperature.
  • All ovens shipped from our New Jersey or Nevada location for quick delivery, and come with two year warranty and lifetime US-based parts and service support.
  • Guaranteed US based phone and email assistance within 30 minutes from our engineers.
