Page 11: Filters With Inpass
Instruction book Filters with inPASS™ The premium range filters are equipped with an integrated inPASS™ valve in the housing. This inPASS™ valve will be used to service the filter and replace the filter element without interrupting operation and compressed air flow. 2920 7199 41... - Page 12 Instruction book In normal filtration operation the air flow is directed into the filter element and passes through several filter media layers before being guided to the outlet port of the filter. When the inPASS™ valve is activated, the compressed air flow is redirected through this valve to the filter outlet. This creates the opportunity to depressurize the filter housing, using the drain valve at the bottom of the filter, and service the filter element.

Page 13: Filters Without Inpass
Instruction book Filters without inPASS™ The standard range filter is not equipped with an integrated inPASS™. The DD+, PD+, UD+, DDp + and PDp+ filters have a differential pressure indicator for sizes 7+ to 45+ and a differential pressure gauge for sizes 45+ to 630+. At start-up and during normal operation, the differential pressure indicator will be yellow;... -
Page 14: Options
Instruction book The differential pressure gauge indicates the pressure drop on an indicative scale from 0 to 750 mbar. Refer to section Service intervals for more information on service intervals. Options Filter connection kit If two or more filters are used in combination, build the filter heads together by means of a serial connection in the correct air flow direction. - Page 15 Instruction book Voltage-free contact A voltage-free switch, mounted in the differential pressure gauge, closes at a pressure drop of 0.35 bar (5 psi) and can be used for remote control or alarm purposes. The maximum switching voltage and current are 30 VAC/VDC and 0.2 A respectively. External power supply Optionally, the smart service indicator can be fitted with an external power supply and alarm contact.
- Page 16 Instruction book Referen Description +VCC from external power supply GND (ground) from power supply Output signal NO (normally open). If needed, the contact can be changed to NC (normally closed) in the settings menu. – Electronic drain The electronic drain is optional on the DD+, PD+ and UD+ filters. The electronic drain is a zero loss, electronically operated drain valve, specially designed to drain oil condensate.
- Page 17 Instruction book If the microcontroller registers a malfunction, the automatic drain valve will automatically change to alarm mode. This alarm signal can be relayed via a potential-free contact. The electronic drain is available for 3 operating voltages: 220 V, 115 V and 24 V (50/60 Hz). An extra electric wiring can be foreseen to connect the potential free contacts and an external test button.

Page 18: Installation
Instruction book Installation General remarks When installing the filter, keep in mind the following: • Be sure that the piping is internally clean, especially downstream of the filter. • Sizing of filter should be done carefully, taking into account the application requirements. Maximum flow capacity, as listed in Chapter 5.4 or 6.4 "Rated flow at reference conditions", should never be exceeded to make sure that filtration performance and filter lifetime are guaranteed. -
Page 19: Specific Remarks
Instruction book Process piping recommendations To reach class 1 for solid particles according to ISO8573-1, it’s recommended to use stainless steel piping or AIRnet aluminum piping. Other types of piping, like brass or copper piping’s are not recommended as the surface roughness is too high, which makes class 1 difficult to reach. inPASS™... - Page 20 Instruction book • Remove the back-cover and insert 3 AA batteries. Make sure to use high quality batteries to ensure functionality. Batteries should at least comply to the following specification: AA size, alkaline, capacity: 2xxx mAh, voltage: 1.5V. • The device will boot up automatically •...

Page 24: Maintenance
Instruction book Maintenance Maintenance When maintaining the filter, keep in mind the following: • On filters with manual drain valve, open the latter at regular intervals to evacuate collected dust or liquid. • In case an automatic drain valve or a solenoid timer drain is installed, manual draining can be carried out by turning the connection nipple of the automatic drain valve counterclockwise. - Page 25 Instruction book 2. Before operating the inPASS™, please check if the circlips (1) is correctly positioned (supported by the inPASS™ groove and the horizontal face on top of the filter head) just below the hexagonal nut. In case of any doubts, please contact your supplier. 3.
- Page 26 Instruction book 2. Place the appropriate tool (wrench, spanner) over the hexagonal nut and make sure there is room for rotational movement as indicated on the lock-out feature. Rotate the inPASS™ valve over 90° in a fluent motion (to not hinder the air flow) in the direction indicated on the lock-out feature.
