This great “rockman” CO2 controller is not only made of stainless steel but also with better anodic treatment that increases the surface thickness and hardness while having a higher resistance to corrosion and anti-rust.
The treatment also provides adhesion for paint in green with a laser engraving of the logo “ISTA”, which looks professional and high quality.
The precision needle valve of the controller which has better precision fine adjustment assures accuracy and reliability in dosing the CO2.
Simple and easy – no tool required, just hand and air-tighten.
