Flow by pressure
The flow applies to a pressure of 7 bar and a temperature of +20 °C. At a higher pressure, it is multiplied by the correction factor; from 100 bar it is 12:
| Pressure (bar) | 7 | 25 | 40 | 64 | 100 |
|---|---|---|---|---|---|
| Flow (l/min) | 4,583 | 13,749 | 22,915 | 36,664 | 54,996 |
Element and accessories
| For this filter: | |
|---|---|
| Spare element | CHPM-018V |
| Condensate drain (ordered separately) | TD420M-230VAC, TD420M-24VDC |
| Wall bracket | CHP-WL |
| Water separator before the filter | CHP cyclone separators |
Where to place it

It goes after the dust or basic filter, before the CHP1S microfilter: it protects the microfilter element, which then lasts longer.
You will find other sizes among the filters of the same stage.
