MAINTENANCE
Please follow the points below to ensure your AOF is running as efficiently as possible by carrying out
periodic maintenance on each system.
Maintenance intervals will vary per installation depending on a few factors which
are….
●
Run hours per week
●
Type of CNC (Lathe or Mill)
●
Type and amount of Coolant / oil being used
Ideally after an installation is completed and a system is operational, standard procedure would be to
use the system for three months and then open the filter housing to check the state of the pre-filter
and main filter.
This will give a rough indication to the current state of the filters after three months of use. Depending
on the factors listed above you may find very clean or dirty filters.
If the filters visually do not seem blocked or restricted after three months of use it is best to remove
them and clean the filters as described below, filters may appear clean but this is not always the
case.
If the filters are dirty or heavily restricted or showing as amber on the gauge or LED panel please
follow the instructions below in order to clean the filters and improve air flow back to design
conditions, failure to do this will result in a less efficient system and if left long enough could possibly
lead to a fault or damage to the mist filter.
Once maintenance has been completed please ensure you note the date as to when the filters had
been cleaned or replaced and keep this in your maintenance logs.
Remember
–
maintenance is vital to ensuring an efficient and effective mist filter!
At intervals of at least every 14 months an LEV test (Local Exhaust Ventilation) will need to be carried
out to ensure your mist filter is operating as designed and up to current standards. This is a
requirement under COSHH.
This can be carried out by our fully trained AirBench Engineers - feel free to contact us to get this test
booked in.
