Ai AT 1.9 cu ft UL/CSA Certified Vacuum Oven

Ai Vac Ovens

The new UL/CSA certified AT1.9 is our most popular desktop vacuum oven. Its slightly larger dimensions than the AT-09 allows for faster purging times, but still maintains a small enough footprint that it works perfectly with a desktop or workbench application.

Oven Features

UL/CSA certified Ai AT 1.9 cubic foot vacuum ovens come standard with stainless steel tubing, stainless steel vacuum & vent valve, oil-filled vacuum gauge, 5 sided pad heating technology and two year warranty. The thermal-conductive aluminum pan shelves provide excellent temperature uniformity inside the chamber, while standard is the 3rd gen LCD low proportional gain temperature controllers keep your oven temperature within +/- 1°F accuracy, in either °F or °C.

New 5-sided Pad Heating Technology

The AT19 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.

Solid Aluminum Shelves

The new AT-19 comes equipped with 5 aluminum pan shelves that maximize even heat distribution of stable temperatures. This creates even, stable temperatures throughout the oven chamber. The chamber can hold a maximum of 10 shelves for added efficiency!


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 = 16.5″ W x 14.5″D x 14″H; Unit = 28″W x 20″D x 21.75″H
InteriorEasy to clean stainless steel.
Safety FeaturesBuilt-in circuit breaker and overheat protection with alarm.
Shelves5 solid aluminum shelves included. Holds a maximum of 5 shelves.
Temp ControlDigital temperature control with timing and alarm. Uniformity of +/- 6% of set-point.
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.

All vacuum ovens are intended for lawful purposes only.

Before Initial Use: Run oven at 400°F without vacuum for a total of 15 minutes to burn off any residue that may have been introduced during the manufacturing process.


  • UL certified.
  • All stainless steel internal tubing & 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 enclosures 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.
