Description

This high-quality pressure regulator is used to reduce the cylinder pressure of approx. 54 bar to a working pressure of approx. 1 to 3 bar. By combining the working pressure gauge and the cylinder pressure gauge, the CO2 supply can be adjusted very precisely, and you can immediately see when it is time to refill the cylinder. The integrated fine needle valve allows very precise adjustment of the CO2 supply for the aquarium. The included bubble counter also enables visual monitoring of the CO2 dosage and helps to fine-tune the supply accurately.

Please keep in mind that all components of the pressure regulator have been permanently bonded by the manufacturer. These can not be unscrewed without causing damage. If the needle valve is removed, the warranty will be void. The hose connection on the fine needle valve is an exception. Due to its fine thread, it is not bonded, so that in the event of a defect, it is not necessary to replace the entire fine needle valve, but only the hose connection.

The Hiwi Pressure Regulator + SV & CV is also available without solenoid valve (SV) and check valve (CV): Hiwi Pressure Regulator

In addition to this pressure regulator, a dual-stage version with solenoid valve (SV) and check valve (CV) is also available, which can be used in aquariums with particularly sensitive fish to completely prevent increased CO2 levels: Hiwi Double Stage Pressure Regulator + SV & CV

  • Turn the working pressure adjustment screw (operating instructions 4) anticlockwise.
  • Close the fine needle valve (operating instructions 5) by turning it clockwise. CAUTION: Tighten only slightly!
  • Position the pressure regulator so that the pressure gauges are facing upwards.
  • Attach and tighten the pressure regulator to the CO2 cylinder using the union nut (operating instructions 7). The union nut must be tightened by hand only! Do not use tools!
  • Ensure that the seal is correctly seated and that the sealing surfaces are clean. If the seal is damaged or lost, please replace it.

Hiwi

Hiwi is a renowned German manufacturer of CO2 pressure regulators. The highest level of quality and a long useful life are in their focus. These high quality standards do not exclude attractive prices, though.

Especially in aquascaping, the addition of CO2 for the plants is something very basic, and thus it is really important to choose good CO2 supplying equipment. Hiwi meets even the highest quality standards in every aspect und is thus the best choice when it comes to CO2 pressure regulators.

Hello, which hose connector fits the pressure regulator? An 18 - 46mm one doesn't fit. It's too big.

A 4/6 mm high-pressure hose can be connected to the pressure regulator. The union nut is slid over the CO2 hose and screwed on tight. You can find more information on commissioning the pressure regulator in the operating instructions: https://www.aquasabi.de/cdn/hiwi/bedienungsanleitung_hiwi.pdf

Excellent pressure reducer

I was annoyed for a long time about my pressure reducer from JBx because it just wouldn't adjust properly. I'm more than satisfied with the new one from HIWI. (read more)
