About Filter regulators

A filter regulator combines particle separation and pressure control in one body, which saves a connection point in the air preparation unit. The range filters at 5 to 50 µm and regulates to outlet pressures between 1 and 17.5 bar. Permissible inlet pressure runs from 10 to 60 bar depending on version.

What matters when choosing

• Thread and DN: Ports run from G 1/8 to G 1, nominal bores from 5 to 25 mm. Thread size alone is not enough as a criterion, because only the nominal bore describes the actual flow cross section.
• Filter rating: 5 to 50 µm. The coarse end is enough for general tool and cylinder supply, finer elements protect sensitive valve technology and trade that against a higher pressure drop.
• Control range and inlet pressure: Lower limits lie between 0 and 1.7 bar, upper limits between 1 and 17.5 bar. The target working pressure should sit inside the range rather than at its edge, and the inlet pressure of 10 to 60 bar has to match the supply.
• Flow rate: Listed values run from 1000 to 15000 l/min. What counts is the peak demand of all downstream consumers, not their average.
• Condensate drain: Manual drain, hand drain valve, semi-automatic and fully automatic versions are available, including a normally closed type. Where the unit sits in a poorly accessible spot, the fully automatic drain is the practical option.

Typical applications

• Central air preparation unit ahead of valve manifolds and cylinders on a machine.
• Supply for pneumatic tools at assembly and workshop stations.
• Packaging and filling lines with fluctuating air demand.
• Paint and coating equipment that requires finely filtered, oil-free air.
• Test benches that need a stable outlet pressure independent of line pressure.
