4 Design and function of the AFS air purification device
The operating principles and basic structure of all AFS air purification devices are the same; they differ
only in scale, ventilation system performance, airflow direction, number of filters used per cross-sectional
area (regardless of device type), color and layout of attachments.
4.1 Operating principle
Aerosols and particles from the coolant lubricant in the machine exhaust air are separated from/filtered out of
the air current in the AFS air purification device.
The separated coolant lubricant accumulates in the bottom area of the air purification device and drains
through the two siphon lines.
The suction output is generated by a motor fan wheel. The motor fan wheel is located in the airflow direction
after the post filter and thus on the clean gas side.
4.2 Design

5.4 Electrical Connections
Safety Instructions:
Electric motors contain dangerous components that are live and rotate during operation. If operated
incorrectly, used improperly, or inadequately serviced, these components can cause damage to
health and property.
The devices are only to be accessed for work if the system has been disconnected from the power
supply. The devices must also be protected from being accidentally reconnected.
The devices' electrical components, such as electric motors, servomotors,
control and monitoring systems, must be connected as specified in the manufacturer’s instructions
and the regulations of the relevant electricity board.
The German Electrotechnology Federation's (VDE) regulations must be adhered to. Work on
electrical components must be carried out only by qualified electricians.
The drive motors for the ventilator wheels are always fitted with thermostat relays or PTC thermistors
for motor protectors and must be connected accordingly.
5.4.1 Electrical Connection of AFS Air Purification Device
The accompanying instruction manual for the engine or engine fan wheel must be observed.
The German Electrotechnology Federation's (VDE) regulations must be adhered to. Work on
electrical components must be carried out only by qualified electricians.
Once the ventilator motor has been connected, it is vital to make sure that the radial wheel rotates
in the direction indicated by the direction arrow on the front of the device before starting up the
air purification device.
Figure 7: Backward cranked radial wheel with direction arrow
If the rotor rotates in the wrong direction, the motor's direction of rotation must be reversed by
changing the electric poles (reversing the phases).

5.4.2 Motor protection
Various motor concepts are built in depending on the device type.
Please inform yourself regarding the built-in motor and its protection devices using the supplied
motor instruction manual or with AFS directly.
The protection devices and installation guidelines described in the motor instruction manual must
be heeded. Make sure that the motor does not restart by itself after a possible fault.
5.4.3 Electrical Connection of AFS Air Purification Devices with Frequency Converters (Optional)
The instruction manual for the frequency converter that is provided and the installation instructions contained
within them must be observed for air purification devices with frequency converters for regulating the flow
rate by controlling the rotation speed of the engine fan wheel.
When AFS air purification devices with frequency converters are operating, a lockable repair switch
must be placed inside the feed line before the frequency converter (DON EN 13053-6.3.1).
The AFS device and the frequency converter must not be serviced unless the frequency converter
and the AFS device have been shut off using the repair switch. While work is ongoing, the repair
switch must be secured with an individualized, lockable closure against unauthorized or accidental
restarting.
The repair switch and the frequency converter as well as the frequency converter and the AFS device
are to be connected by a qualified and competent specialist and in accordance with all current
guidelines and VDE regulations.
AFS partly parameterizes and presets the frequency converters. Adjustments that deviatefrom the
standard are documented in the instruction manual for the frequency converter, see Figure 8.
The currents in the frequency converter are not shut off when the frequency converter's motor is
turned off.
If the frequency converter's operating mode is set to "Motor ON" and the frequency converter is cut
off from the grid, the motor will start immediately once the frequency converter is back on the grid.

Before the AFS device is turned on, the protective conductor system of the entire system must be inspected
and safe operation ensured.
A ground bolt is mounted ex factory. Depending on the device type, multiple locations have been
provided for ground bolts at the base of the device or the carrier.
If necessary, the ground bolts can be mounted elsewhere. The ground bolt is to be connected to the
metal housing structure by a professional.
5.6 Startup Operations
Before the device is turned on, all electrical wires, pipes, ducts, and the AFS device must be examined for
proper installation and mechanical damage and leaks.

Additional Information:
If the frequency converter is parameterized ex factory, then the corresponding parameters will be
noted in the instruction manual that is delivered with the frequency converter, see Chapter 5.4.
The operating modes and on/off procedures can be found in the frequency converter's instruction
manual.
The currents in the frequency converter are not shut off when the frequency converter's motor is
turned off.
If the frequency converter's operating mode is set to "Motor ON" and the frequency converter is cut
off from the grid, the frequency converter will start again at the last selected setting immediately upon
coming back on the grid. Where applicable, the motor may start.
To ensure safe suction output, the frequency converter is not to be operated below its minimum
frequency of 70% of the maximum frequency.
6.3 Follow-up time
The AFS air purification device should continue to run for approximately 10-15 minutes once the process has
ended.
6.4 Motor protection: Acknowledge faults
Various motor concepts are built in depending on the device type.
Please inform yourself regarding the built-in motor and its protection devices using the supplied motor
instruction manual or with AFS directly.
The motor protection is already integrated in EC motors from the manufacturer ebm-papst. In case of fault,
the motor automatically turns off. Before the motor can start again, the fault must be acknowledged and the
motor reset by momentarily disconnecting the power supply.

7 Maintenance
Failure to maintain the device as specified in the AFS operating instructions will void the warranty or
guarantee!
7.1 Maintenance Work and Cycles for Oil and Emulsion Mist Separation
All maintenance work on a device must be performed exclusively after the device has been turned off
and by trained personnel familiar with the device.
If multiple AFS air purification devices are operating in conjunction with one another, ALL the devices
must be disabled for maintenance to be performed. Low pressure will persist throughout the entire
extraction pipe system for as long as networked devices are turned on. Where applicable, device
doors must not be opened. There is an increased risk of injury.
Maintenance cycles are to be set in accordance with the type of process and degree of contamination
in the air that is to be cleaned. The degree of pollution in the device as well as the separator elements
must be examined and then cleaned or replaced as needed.
Figure 10: Filter arrangement within AFS air purification devices
Never change the order, number or installation position of the separation and filter elements as this
will render the device inoperable.
The device must only be operated with AFS-approved separation/filter elements.
The separation and filter elements may be laterally removed from the device for cleaning or
replacement.

7.1.1 Metal mesh preliminary separator (pos. • )
Figure 11: Metal mesh preliminary separator
The preliminary separator is made of a corrosion-resistant metal mesh, is non-wearing, and can be
cleaned/rinsed:
Cleaning interval: Clean when obviously clogged and dirty, i.e. if full of shavings, hardened oil, abraded
material, grease residues.
And at least every 4 weeks.
Directions: Use hot water and a grease-removing cleaning agent with a high-pressure cleaner or
in a component washing system.
Parts will have oil and coolant lubricant residue. Wastewater must be disposed of properly and in an
ecologically responsible manner.
7.1.2 Preliminary filter fleece (pos. ‚ )
Figure 12: Fleece preliminary filter. Depicted without alternate frames
The preliminary filter comprises filter grade G3 filter fleeces, which must be replaced when they become
clogged and dirty.
Replacement interval: Clean when obviously clogged and dirty, i.e. if full of shavings, hardened oil, abraded
material, grease residues.
And at least every 4 weeks.
The preliminary filter fleeces can be replaced with conventional filter grade G 3 filter fleeces with a fleece
thickness of 20 mm.
Parts will have oil and coolant lubricant residue. Proper and ecologically responsible disposal is
absolutely necessary.

7.1.3 Longlife separator (pos. ƒ )
Figure 13: Longlife separator: Arrow must point in the direction of flow
The Longlife separator distinguishes itself through its high-performance self-cleaning action and must
therefore only be cleaned when visibly and seriously clogged or dirty.
Cleaning: self-cleaning.
If, despite its self-cleaning action, the Longlife separator should nonetheless become extremely dirty
or clogged, i.e. full of oil and emulsion residues, hardened oil, the entire separator can be cleaned
using warm water and a grease-removing cleaning agent.
The Longlife separator must not be opened or disassembled.
It is vital that the separator be installed in accordance with the air flow direction arrows on the
separator’s frame. Otherwise the device will no longer function properly.
If necessary, the writing on the Longlife separator can be arranged upside down relative to the
airflow direction and the installation position.
Damaged Longlife separators must be replaced immediately.
Improperly installed or damaged Longlife separators will cause diminished or unsatisfactory
separation performance. Under those conditions, the device will no longer function properly.
Parts will have oil and coolant lubricant residue. Wastewater must be disposed of properly and in an
ecologically responsible manner.

7.1.4 Post filter H13 (Pos. „ )
Figure 14: H13 post filter
The following are installed as subsequent separators or post filters:
- HEPA filter H13 (Pos. „ )
- Metal mesh follow-up separator (pos. … )
The separation performance of the H13 follow-up separator is higher than that of the metal mesh
follow-up separator (see Chapter 7.1.5). The metal mesh follow-up separator is not recommended
for processing installations which produce smoke and vapor.
The H13 post filter will become clogged in the course of its operation, diminishing the AFS air purification
device's suction output.
If the H13 post filter is clogged or if the air current is significantly reduced due to a saturated filter, then the
H13 post filter must be replaced. To do so, undo the M6 screws on the terminal strips so that the post filter
can be pulled out.
The H13 post filter cannot be cleaned.
Replacement interval: Replace when there is a noticeable reduction in the device’s extraction performance
due to oil and emulsion residue deposits, or hardened oil.
To replace, undo the M6 screws on the terminal strips so as to allow the suspended particle filter to
be pulled out. When fitting a new post filter, the filter’s rubber sealing strips must be on the suction
side (in the terminal area).
The filter bags must be vertical.
If the H13 is not promptly replaced, it may tear. There will therefore be no filtration effect and the
AFS air purification device will be inoperative. The AFS air purification device must be turned off
immediately and a new H13 post filter must be installed.
Parts will have oil and coolant lubricant residue. Proper and ecologically responsible disposal is
absolutely necessary.
