The Excalibur 9-Tray (3926TB) is a large cabinet-style dehydrator with horizontal airflow and 15 square feet of drying space. The Nesco Gardenmaster FD-1040 is a compact round unit that starts at four trays and expands to twenty. Both are built for bigger batches than a typical mid-range machine, but they get there in different ways. This comparison uses each manufacturer’s published specs, not our own lab testing.

Airflow and Drying
The Excalibur’s fan sits at the back and pushes air horizontally over all nine trays, the layout most people look for when they want even results without rotating trays. The Nesco’s top fan sends air down an outer chamber and then across each tray. Both are designed to spread heat evenly, but as with any tall stack, check the outer trays near the end of a run. See horizontal vs vertical airflow.
Capacity
The Excalibur has one size: nine large trays. The Nesco starts smaller and grows. With four trays it holds much less than the Excalibur, and each additional tray adds about a square foot. At its 20-tray maximum the Nesco offers more total tray area on paper, but the stack gets tall.
Controls and Temperature
The Excalibur runs hotter (up to 165°F) but not as low (105°F minimum). The Nesco goes from 90°F to 160°F, better for delicate herbs but slightly short of the 165°F ceiling. Either works for jerky if you heat the meat to 160°F first. The Nesco also has the longer timer, 48 hours against 26. See our temperature and time chart for settings by food.
Size, Weight and Warranty
The Excalibur is a 24-pound cabinet that needs a permanent spot. The Nesco base is about 11 pounds and roughly 16 inches square before you add trays. On warranty, Excalibur lists 10 years. Nesco’s product page doesn’t state its warranty terms, so confirm them with the seller.
Which One Should You Buy?
- Choose the Excalibur if you regularly dry large batches, want a fixed-size cabinet and a long warranty.
- Choose the Nesco if your batch size varies, you want a 48-hour timer and a 90°F minimum, and you prefer to expand step by step.
