Product Features
Compact construction for convenient pneumatic air preparation.
The push-in self-locking pressure-adjustment mechanism helps prevent unintended changes to the setting.
The filter separates water and solid particles with low pressure loss and efficient water separation.
The transparent viewing dome allows the oil-drip quantity to be observed directly.

Included Configuration and Compatible Connections
Parameter
Details
Supplied functional assembly
Filter, regulator and lubricator combination. Its component-family references are identified below; the filter/regulator and lubricator are parts of this assembly, not additional items to order to obtain the stated function.
Pressure gauge
Supplied in the shape and scale specified above.
Replacement bowl, filter and service parts
Use parts explicitly selected for this body family, size, bowl material and drain type. The construction numbers identify internal parts; they do not establish standalone ordering codes, service-kit contents or package quantities.
Application connection
Match the inlet and outlet thread standard and nominal size to the pneumatic circuit. The catalog does not restrict this air-preparation product to one named directional-valve or cylinder family.

Drawing dimensions are in millimeters unless a thread or another unit is stated. Each local callout retains its original view and datum; separate values must not be added to create an unpublished overall size. Gauge and bracket geometry is shown only as reference when those items are omitted by the current code.

Flow graph
Flow capacity in L/min versus outlet pressure in MPa.
Printed flow-axis range
0–3000 L/min
Printed outlet-pressure scale

Pressure-characteristic graph
Inlet-pressure labels through 0.9 MPa; outlet-pressure labels 0.18–0.22 MPa, around the illustrated 0.20 MPa setting.
Reading the curves
The graph axes and endpoints are plotting references, not rated flow claims. Read the actual curve at the required operating condition in the PDF.
Other Series Ordering Choices
These are catalog alternatives. They do not change the selected configuration identified above and are not additional supplied parts.
Parameter
Details
Body/port versions
A Series: 1500C = 1/8 inch, 2000C = 1/4 inch; B Series: 2000C = 1/4 inch, 3000C = 3/8 inch.
Thread options
Blank PT; G; T for NPT. Where a gauge is supplied, PT uses MPa or kgf/cm² and psi, G uses bar, and NPT uses psi.
Drain choices
Blank: semi-automatic. Automatic A is listed for the B Series only. The specification table mentions manual-drain performance but the ordering chart does not give a manual-drain code in this edition.
Pressure type
Standard: maximum adjustable pressure 0.9 MPa; L: maximum 0.4 MPa. The lower limit depends on the current product and drain arrangement.
Filter element
Blank: 40 µm; W: 5 µm.
Installation and Catalog Notes
Use the inlet and outlet directions shown on the body and in the dimension drawing. The selected drain mode and drain connection must be accounted for in the installation.
The push-in lock is part of the pressure-adjustment mechanism; lock the setting after adjustment. The plotted regulation characteristic is shown around the catalog setpoint and does not replace the selected pressure-range limit.
Use ISO VG32 or an equivalent lubricant, as stated in the catalog. The oil-bowl capacity above is a capacity specification, not a stated quantity of oil supplied with the product.
Select fittings, gauges and replacement parts for the stated version and interfaces. A matching nominal port size alone does not establish interchangeability with a different body series or catalog edition.
