This fryer is unique: it literally filters the oil by itself. Once your frying is done, turn off the appliance and turn the dial to "automatic filtration". When the oil starts to cool down, it will go through a sieve before being drained into the oilbox underneath. Thus, your oil will always be clean and can be used many times. Deep-frying with Oleoclean Pro is a real pleasure! Its capacity of 3.5 L allows you to prepare up to 1.2 Kg of food. It has a stainless steel removable bowl and is also equipped with an on/off switch and a digital timer. The lid can be used during cooking. It has a permanent metallic filter and a viewing window. The fryer can be dismantled very easily and is very easy to clean: bowl, lid, frying basket and oilbox are dishwasher safe. Oleoclean Pro is a semi-pro fryer with a cool zone and an immersed heating element. It is definitely the best Tefal fryer for French fries lovers: powerful, convenient, ingenious and easy to use. It has all you need to prepare perfect French fries and delicious fried meals.
