FAQ

What is the function of the lockable knob on the Bosch 0821302520?

The knob is a safety and stability feature. It allows you to set the desired output pressure and then lock it in place by pushing the knob down. This prevents accidental pressure changes due to vibration or unintentional contact.

Can I use this regulator for media other than compressed air, like nitrogen or water?

This regulator is specifically designed and specified for use with filtered compressed air. Using it with other gases like nitrogen or liquids like water is not recommended by the manufacturer and can lead to improper function or damage to the internal seals and diaphragm.

Does the 0821302520 regulator have a relieving function?

Yes, this is a relieving type pressure regulator. This means that if the pressure on the downstream side increases above the set value (e.g., from a cylinder retracting), the regulator will automatically vent the excess pressure to the atmosphere to maintain the set point.
