Test pressure: 13 bar (180 psi)
Temperature range: -10C to + 120C
(other temperature ranges on request)
Bypass setting:
Pressure side: Δ p 3.5 bar 10%
Suction side: Δ p 0.25 bar 10%
Filter head material: GDAL
Spin-on cartridge material: St
Sealing material: NBR/AL
Maintenance indicator setting: Δ p 2.2 bar 10%
Indicating range vacuum gauge: -1 bar to +1.5 bar
Pressure setting vacuum switch: 200 mbar
Type of protection (suction side) IP 54
Electrical data of maintenance indicator:
Max. voltage: 250 V AC/200 V DC
Max. current: 1 A
Contact load: 70 W
Type of protection: IP 65 in inserted and
secured status
Contact: normally open/closed
Cable connection: M20x1.5

The switching function can be changed by turning the electric upper part by 180 (normally closed contact or normally open contact). The state on delivery is a normally closed contact. By inductivity in the direct current circuit the use of suitable protection circuit should be considered. Further maintenance indicator details and designs are available in the maintenance indicator data sheet.

We draw attention to the fact that all values indicated are average values which do not always occur in specific cases of application. Our products are continually being further developed. Values, dimensions and weights can change as a result of this. Our specialized department will be pleased to offer you advice.

We recommend you to contact us concerning applications of our filters in areas governed by the EU Directive 94/9 EC (ATEX 95). The standard version can be used for liquids based on mineral oil (corresponding to the fluids in Group 2 of Directive 97/23 EC Article 9). If you consider to use other fluids please contact us for additional support.

Pi 270 Technical Specifications
9. Installation, operating and maintenance instructions
10.1 Filter installation
When installing the filter make sure that sufficient space is available to remove spin-on cardrige. Filter should be installed with the spin-on cartridge pointing downwards. The maintenance indicator must be visible.
10.2 Connecting the electrical maintenance indicator
The electrical indicator is connected via a 2-pole appliance plug according to DlN EN 175301-803 with poles marked 1 and 2. The electrical section can be inverted to change from normally open position to normally closed position or vice versa.
10.3 When should the filter element be replaced??
1 . Filters equipped with visual and electrical maintenance indicator:
During cold starts, the indicator may give a warning signal. Press the red button of the visual indicator once again only after operating temperature has been reached. lf the red button immediately pops up again and/or the electrical signal has not switched off after reaching operating temperature, the filter element must be replaced after the end of the shift.
2 . Filters without maintenance indicator:
The filter element should be replaced after the trial run or flushing of the system. Afterwards follow instructions of the manufacturer.
3 . Please always ensure that you have original MAHLE spare spin-on cartridges in stock.
10.4 Spin-on cartrige replacement
1 . Stop system and relieve filter from pressure.
2 . Unscrew the spin-on cartridge by using a filter wrench by turning counter-clockwise.
3 . Make sure that the order number on the spin-on cartridge corresponds to the order number of the filter plate.
4 . Oil the seal of the spin-on cartridge.
5 . Spin-on cartridge must be installed according to the printed instructions.
