Experience pressure fermentation made simple with the FermZilla 30L All Rounder—the industry's most popular PET pressure fermenter. This complete kit includes everything you need: dual carbonation caps, weighted mesh filter with float for exceptional clarity, and the proven Red BlowTie spunding valve for controlled pressurised brewing. The upgraded Easy-Grip lid ring and reinforced hex base eliminate tedious adjustments, while minimal cleaning requirements save you valuable time. Designed for busy brewers who refuse to compromise on quality, it's the ideal entry point into pressure fermentation or the perfect upgrade for those seeking superior oxygen management during transfers. Brew smarter, not harder.
We have a great breakdown about the benefits of pressure fermentation here, and a guide to closed transfer here.
We would also still recommend getting a CO2 Gas to be able to transfer to a keg/bottle/can or dispense directly out of the unit. As these units were designed to be fermenting and pressure transfer vessels for your delicious cargo.

Warnings:
Please read the instructions thoroughly before use.
Keeping the units out of direct sunlight is a must for all PET fermenters. Sunlight degrades PET.
Please note:
When using this vessel under pressure. You must perform a water pressure check to ensure your connections are leak proof. To do this. Fill your FermZilla up with water, then apply a minimum of 15psi pressure to the vessel. Check for leaks around all Cap / Threads.
Surface indentations occasionally appear during shipping—a minor cosmetic consideration that actually reflects superior engineering. Your FermZilla 30L All Rounder is purposefully designed with controlled flexibility to absorb impacts from cold crashes and rough handling, safeguarding structural integrity while preserving pressure performance. This deliberate material property prevents brittle failure and extends equipment lifespan. Minor dents naturally resolve through normal fermentation cycles and positive pressure application. Your fermenter arrives battle-tested and ready to deliver consistent results batch after batch. Replacement is warranted only in the exceptionally unlikely event of white stress marks or plastic damage. Invest in equipment built to endure.
