Differences Between Ninja OL601 vs FD401

The main difference between the two models is the number of cooking functions each has to offer. Both models come with a set of cooking functions to elevate your cooking experience. Second visible difference that you’ll note right away is the appearance. Let’s find out in detail!

Appearance and Design

While all air fryers work essentially the same, but you might prefer the design of one air fryer over the other. Ninja has OS, OP, FD and OS series of air fryers with distinctive design that’s both functional and attractive.

Ninja OL is a recently released series with OL601 being released in September last year which is pretty new. Ninja OL601 is both an air fryer and an electric pressure cooker combined into one handy appliance. In terms of appearance and design it feels Ninja took some inspiration from Elon Musk’s starship vehicle – or am I the only one with this thought?

Ninja OL601 has a stainless-steel exterior with black accents and aesthetic design which is both easy to use and stands out from the crowd. This machine sitting on your kitchen counter will surely make some of your friends envious. The pressure cooker steam fryer has measurement of 15.39×14.21×14.25 Inches with weight of 25.1 pounds which is pretty heavy but given the huge size and durable material, its justified.

On the other hand, Ninja FD401 Foodi measures 16×14.57×14.2 inches which is slightly wider and taller than Ninja OL601 pressure cooker and also it weighs 26 pounds. Whether you decide to buy Ninja OL601 or FD401, you got to have a dedicated spot on the kitchen counter because it would be very unwise to always move these machines around.

Cooking Functions

Air fryer / pressure cookers are one of the most versatile cooking appliances on the market and you can cook a range of foods from chicken and fish to veggies and more. Not only that, you can also reheat pizza leftovers from last night. Ninja Foodi OL601 and Ninja FD401 comes with a number of cooking functions to provide you the cooking experience of your life. With these cooking appliances, you would easily be able to replace a dozen of appliances for it can do it all.

Is there anything that you can’t do with Ninja OL601 and FD401? I hope not!

Lid Design

What we have seen normally in Ninja pressure cooker air fryers, that every model comes with two separate lids. The air fryer lid is attached to the body via hinge permanently while pressure cooking lid is removable. The same goes with Ninja FD401 which has two separate lids for air frying and pressure cooking.

On the other hand, Ninja OL601 has improved design and comes with only one lids and a slider button to unlock 3 cooking modes (Pressure Cook, Steamcricp, Air Fry/ Stovetop). We love the new lid since you don’t have to swap lids anymore and you can use all 14 cooking functions under one lid. Smart right?

3 Layer Cooking

Layered cooking is a new concept introduced by Ninja with Ninja OL601 pressure cooker steam fryer. Using a two layered rack you can stack chicken, veggies and grains and cook all of them simultaneously using Steamcrisp technology. This feature of Ninja OL601 model comes in handy especially when you have guests on the table and you need to put food on the table as soon as you can. Ninja Foodi FD401 pressure cooker does not share this feature, although it does have TenderCrisp technology but 3-layer cooking is unique to OL601 pressure cooker.

Control Panel

Buttons, Touchscreen, LCD displays, push buttons and more, these are different control panel settings that you will come across while hunting for any advanced pressure cooker on the market.

Ninja OL601 pressure cooker comes with a life size accompanied by a dial to choose the cooking function required. On the other hand, Ninja FD401 has a touchscreen control panel which is super easy to follow. If you know how to operate a smart phone, you will easily be able to navigate these pressure cooker models.


There is no denying that Ninja appliances are extremely well received in the market. Ninja Foodi FD401 has received incredible 4.8/5 star rating from about 29 thousand users around the world out of which 96% are extremely happy and satisfied with the cooking results.
