Pressure regulators are irreplaceable in many pressure circuits to reduce high pressure. Tools and machines often require lower pressures than the compressed air circuit supplies. Some tools require vented regulators, e.g. nail guns; lower pressure on blowguns reduces the risk of accidents; less air consumption reduces costs and noise emissions. There are also suitable pressure regulators for drinking water circuits. Small inline built-in parts with fixed output pressure save space and protect against accidental adjustment.
Hose rupture protection saves equipment and employees from injury and damage by whipping the hose. Once triggered, they can be reset and reinserted.
