This Dual Gauge CO2 Pressure Regulator was purchased from Amazon last year but never used due to not proceeding with tank. For your information it will is designed for aquarium tanks, featuring a solenoid valve for precise control of CO2 pressure. Made from stainless steel and aluminium alloy, this regulator is durable and efficient. The package includes a 220V Aquarium CO2 Regulator with W21.8 model, suitable for regulating CO2 pressure in the range of 40~80psi. The inverse bubble function is easy to use by adding 4/5 water before operation. This product is a reliable choice for maintaining the optimal CO2 levels in aquarium tanks. I paid £48 for it so genuine bargain to clear no offers please.
