Forced / Natural Convection Oven Programmable Energy Saving 27L With External Transformer Overview
The Forced / Natural Convection Oven Programmable Energy Saving 27L (Yamato DNF301) is a 27 L laboratory convection oven that combines forced and natural circulation in a single chamber, operating from ambient +15°C up to 260°C. Yamato Scientific engineers this unit for repeatable constant-temperature work, and LabSupplies.com supplies it as an authorized dealer.
A digital controller adjusts air velocity across 10 stages, while a front damper tunes chamber airflow to match each load. Insulation and heat tightness hold temperature stable, and tight dust sealing keeps particulates out of the chamber. Interior surfaces use stainless steel plate; the exterior is chrome-free electrogalvanized carbon steel finished with a chemical-proof baking coating.
Each oven ships with an external transformer in either 115V or 220V configuration to match your facility power. Built in Japan, the unit weighs 180 lbs and measures 36 × 36 × 40 in. Manufacturing is backed by ISO 9001:2015 and ISO 14001:2015 certification.
Key Features
- Dual circulation: forced and natural convection in one unit covers gentle drying and faster, uniform heating.
- Energy-saving program: dedicated program function reduces power consumption during extended cycles.
- 10-stage air velocity: digital controller sets airflow speed precisely for delicate or dense loads.
- 99-step programming: repeat operation, auto start, auto stop, and quick auto stop automate multi-stage profiles.
- Front damper control: adjustable damper position optimizes chamber exhaust and circulation per application.
- Fluorescent display: interactive input and a calibration off-set function support accurate, readable setup.
How to Choose the Right Convection Oven
Matching a convection oven to your workflow comes down to chamber size, the heating profile your samples tolerate, and how the oven integrates with site power and controls. Weigh these axes .
- Capacity: the 27 L chamber suits moderate batch throughput; size it to your largest routine load plus airflow clearance.
- Temperature range: an ambient +15 to 260°C span covers drying, baking, and most thermal conditioning tasks.
- Circulation type: forced convection speeds uniform heating, while natural convection protects light or airflow-sensitive samples.
- Control type: programmable 99-step operation favors recurring multi-stage protocols over single-setpoint manual ovens.
- Voltage: confirm 115V or 220V to match available circuits and the included external transformer.
- Footprint and weight: verify bench or floor space for a 36 × 36 × 40 in, 180 lb unit before delivery.

Frequently Asked Questions
What is the operating temperature range of the DNF301 oven?
The DNF301 operates from ambient +15°C up to 260°C. That span supports drying, baking, and thermal conditioning across most laboratory protocols.
What is the chamber capacity and overall footprint?
Chamber capacity is 27 L. The unit measures 36 × 36 × 40 in (L × W × H) and weighs 180 lbs, so confirm bench or floor clearance before installation.
What is the difference between the two DNF301 models?
Both models are functionally identical 27 L programmable convection ovens; the only difference is power input. DNF-301-115V runs on 115V and DNF-301-220V runs on 220V, each shipping with an external transformer.
What materials are used in the oven construction?
The interior is stainless steel plate. The exterior uses chrome-free electrogalvanized carbon steel coated with a chemical-proof baking finish for durable resistance to lab environments.
Does the oven support programmable cycles?
Yes. The DNF301 includes 99-step program operation with repeat operation, auto start, auto stop, and quick auto stop, allowing automated multi-stage temperature profiles.
Can airflow be adjusted for sensitive samples?
Yes. Air velocity is digitally adjustable across 10 stages, and a front damper tunes chamber circulation. The oven also offers both forced and natural convection modes for delicate loads.
