## Description

Selenoid

## Features

- 4 Liter Capacity. That is 2x larger than the size of our competitors’ CO2 generator systems. Holds 600g-800g of citric acid and sodium bicarbonate, aka baker soda powders.
- Professional CO2 Kit With All Accessories Needed For A Complete Setup! 4 Liter SUS304 stainless steel bottle / DC mini solenoid / Regulator / Precision needle valve / Bubble counter / CO2 diffuser / CO2-graded tubing / Plastic funnel and measuring cup.
- Safety! The wall of the bottle meets the safety requirement - 1.5mm thick SUS304 stainless steel. It can sustain pressure up to 1137 PSI (80kg/cm2). The built-in safety valve will open automatically when the inside pressure exceeds the safety threshold.
- 12V DC Instead of AC Power. DC solenoid runs on very low voltage and generates almost no heat. The solenoid is warm to touch and is super quiet. No humming noises.
- Attentions: The required powders to generate CO2 gas are NOT included! You will need citric acid and sodium bicarbonate powders.
