Description
With a flow rate of 1300 Nl/min and a control range of 0 to 4 bar, the filter regulator 5611B521 supplies downstream consumers with filtered air, port G 1/8. The adjusting knob latches and can be locked against accidental adjustment. Type 5611B521 uses a rolling diaphragm that combines precise control and high flow with low friction. The regulator compensates for inlet pressure fluctuations. Regardless of pressure, the RA drain empties the bowl by itself, port G 1/8. A pressure gauge is not included. For a gauge, pressure switch or extra air outlet, the 5611B521 has a G 1/8 port on the front and rear.
Key features
- 20 µm filter rating protects downstream pneumatics.
- Control range 0 to 4 bar: set the working pressure to suit the consumer.
- Flow rate 1300 Nl/min as measured by the manufacturer.
- Inlet pressure up to 10 bar permitted.
- Condensate: RA fully automatic drain on filter regulator 5611B521.
- Temperature -10 to 50 °C for medium and ambient.
Applications
It goes where line air has to be cleaned and brought down to the working pressure of a machine.
