The LAC bench-top oven features horizontal recirculating airflow and exceptional temperature uniformity. The result is proven reliability in demanding production and laboratory applications, such as curing, drying, sterilizing, aging, and other process-critical procedures. The high-performance oven delivers temperatures up to 260°C (500°F).


Horizontal Airflow for Ultimate Temperature Uniformity
The LAC uses horizontal recirculating airflow to ensure uniform temperatures throughout the oven. A high-volume fan circulates air through perforated, stainless steel walls to create a constant horizontal airflow across all sections of the oven.


New Controls Are Esay To Use
Improved controls are easy to use for both simple and complex applications. Single and multiple-temperature applications can be started with the push of a button. Multiple temperature operations are controlled by up to eight programs, with eight ramp and soak segments in each program. Other features include a large, bright LED temperature display, a 32 character LCD status panel, and high-limit temperature protection.


Easy To Clean and Service
Cleaning is easy due to the scratch-resistant, baked enamel exterior, stainless steel interior, and smooth door surface. Servicing is easy due to convenient access to the heater and fan.

The reversible door can be mounted to open from either the left or right, permitting easy access when the oven is placed in a corner.


Superior Quality
The Despatch LAC features a sturdy, welded, double-wall construction, three inches of glass fiber insulation, and heavy-duty gaskets.

Each oven receives a thorough quality and performance test before it is shipped. Heating elements carry a five-year warranty. All models are UL listed.
