If you want to pressurise the Fermentasaurus, this special pressure lid includes a pressure relief valve and stainless ball lock posts (these are the same posts that are often seen on home brewing kegs).
This special pressurisable lid is also supplied with a silicon dip tube with float. The floating dip tube is a design that when the product is drawn out of the Fermentasaurus it is always drawn from the top where the beer is most clear.
This greatly improves the speed at which you can drink clear beer directly from the fermenter, even when the yeast hasn't completely settled to the bottom.
In addition, the pressure kit allows pressurised transfer from the Fermentasaurus to ball lock kegs. All you need is a length of beer line and 2 ball lock liquid disconnects.
