Laboratory Forced Air Drying Oven
The FAO Series combines PID-controlled heating with forced-air circulation through a dedicated airflow channel for controlled laboratory drying, conditioning and thermal-processing applications.
Twelve standard references cover six chamber volumes from 16 L to 220 L. Each capacity is available in a 250 °C or 300 °C configuration, allowing the required temperature range and chamber size to be selected independently.
Key Features
Forced-air circulation for controlled chamber temperature
Forced-Air Circulation
A dedicated airflow channel distributes heated air through the working chamber and supports the specified temperature-uniformity performance.
PID Temperature Control
LED microprocessor controller with timing function and over-temperature alarm. Display resolution is 0.1 °C and specified temperature stability is ±1 °C.
304 Stainless-Steel Chamber
Mirror-polished 304 stainless-steel working chamber designed for routine laboratory cleaning and maintenance.
Adjustable Air Exchange
A front-mounted damper provides adjustment of chamber air exchange during operation according to the intended drying process.
Air Circulation
Loading and airflow influence drying behaviour
The FAO Series uses forced-air circulation through a dedicated airflow channel to distribute heated air within the working chamber. This supports consistent thermal conditions throughout laboratory drying cycles.
Specified temperature uniformity is ±3% at 100 °C. Actual temperature distribution may be influenced by sample loading, container geometry, shelf position, airflow obstruction and damper setting. Loads should therefore be arranged to preserve adequate air circulation around the samples.
Series Architecture
Six chamber sizes, two temperature ranges
All selected references use a 304 stainless-steel working chamber, two shelves and AC 220 V / 50 Hz electrical supply. Select the required reference according to chamber volume, maximum temperature and heating power.

Specified temperature stability is ±1 °C, with a display resolution of 0.1 °C. The timing function covers cycles from 0 to 9999 minutes, and the controller incorporates an over-temperature alarm.
Temperature stability describes variation over time at the sensor position. Temperature uniformity describes temperature distribution within the chamber and is specified as ±3% at 100 °C. Actual distribution may vary according to chamber loading, shelf position and airflow conditions.
