INTRODUCTION
Overview
Thank you for choosing AirBench BD as your partscleaning system. Please read this document before
installation and use.
This document details maintenance activities which are essential to the safe use of your AirBench. We
recommend that the Responsible Person reads this manual fully prior to installation and operation of the
AirBench.
This document refers to the AirBench BD type. Refer to the Commissioning Certificate provided with this unit
for further guidance.
About AirBench
AirBench is a self-contained parts cleaning station which utilises a venturi system to generate airflow and a final
multi-stage filter to contain coolant and swarf.
Some models vary in filtration and filtered air delivery point.
It is used by operating a foot pedal to trigger airflow; then operating a hand gun to blow excess coolant from
parts.
About this Document
This document provides general maintenance and operation instructions for the AirBench BD range. It should
be read in conjunction with the Commissioning Certificate supplied with the unit. If you have any concerns or
doubts about maintenance or operation of this unit, contact the manufacturer.

INSTALLATION
General
Unpack the unit and check for damage, if not already completed.
The AirBench must be installed on a flat and level floor capable of carrying the weight of the unit. For nominal
unit weights, see Specifications section at rear of manual. When determining an installation location, be aware
that the air exhaust must discharge somewhere. Do not position the unit so rear outlets are blocked.
Air Supply
The unit must be connected to a supply of compressed air at 8 bar. A series 19 air inlet is provided as
standard.

COMMISSIONING
General
The initial commissioning and testing of your AirBench has been performed prior to delivery. However, as part
of in-house commissioning we recommend that you complete the following tasks and record the results as
appropriate in the system logbook.
In House Commissioning
The following tasks should be completed by a responsible person; for example, the Health and Safety Officer,
or Director, responsible for this process.
-Review the commissioning certificate for this unit, in particular any notes made by our engineer in relation to
use.
-Ensure all operators are trained to use this machine and are aware of the effective capture zone in which
they should aim to work.
-Ensure all operators are aware of the filter maintenance routine required for this machine.
Once complete, you should note this on the commissioning certificate and retain the certificate for future
reference.
As operating conditions vary, each installation will vary in maintenance needs and this is best established by
empirical means, regularly checking filter condition in the first weeks of operation to establish a procedure.
Reduced airflow is a key indication of filter condition. If the filter pressure gauge on the right side of the unit is
showing in the red zone while operating, this indicates low airflow and filters should be checked and cleaned or
changed promptly, according to the instructions contained within this manual.
We recommend keeping the commissioning certificate, Quick Start guide, and logbook with the machine at all
times for operator access.
If in doubt please contact the manufacturer quoting the machine serial number.

OPERATION
This page contains the same information as the Quick Start guide provided with your AirBench.
Prior to use
Check the system logbook to ensure no routine maintenance is required.
General use
To use AirBench, ensure it is plugged in the air supply and your compressor is switched on.
Check the filter pressure gauge on the side of the bench. If the needle on the gauge is showing within the RED
zone while the unit is in operation with peddle depressed, check the filter condition –they may require cleaning
or replacement.
You should aim to work within the enclosure of the unit. Working outside the front face of the enclosure will lead
to escape of particulate.
Record any maintenance you have undertaken, or any that is required, in the logbook.
Wear appropriate PPE. Use of this unit may expose operators to high noise
levels due to compressed air; and splashed coolant to hands. Wear gloves and
hearing protection.

MAINTENANCE
Filter care
The filters are not self-cleaning and must be maintained / cleaned / replaced as described below. Proper filter
care is essential for the effective operation of your AirBench. If in doubt, contact the manufacturer for advice.
The filter pad fitted is a multi-stage M5 pad. Take note of the pad installation method prior to removing existing
pads.
All filters should be regularly checked for wear, damage, or by-passing.
When completing filter maintenance activities these should be recorded in the accompanying log sheet.
Take precautions and wear appropriate PPE when handing filters.
They may contain hazardous materials.
FILTER ACCESS
Filters are accessed by removing the front door of the unit. Unclip the lid of the swarf bin, and lift lid to remove –
taking care not to damage ducting. The bin can then be slid forwards to remove and empty.
WARNING! Risk of personal injury.
•Always isolate the air supply before changing filters or removing any
components from the BD.
•Use necessary PPE

Wear appropriate hand protection.
SPARES
See the specific list for your machine shown on the commissioning certificate.
When ordering, please contact the manufacturer quoting the serial number of this machine.

Other routine maintenance
We recommend the following tasks be performed on a regular basis. Suggested intervals are shown and these
should be reviewed dependent on level of use. Actual completion of these operations and any variation to these
recommended maintenance intervals should be recorded in the system logbook.
If completion of routine maintenance tasks suggests additional issues, contact the manufacturer for advice.
DUCTING
When checking / changing filters. Check flexi ducting for damage and replace if required.
SURFACE
At least monthly, or as routine, check the surface condition. Clear any blocked holes.
AIR SYSTEM
At least 6 monthly. Clean and check for damage / leaks. Replace any damaged components.

THOROUGH EXAMINATION AND TESTING
If AirBench is used as an LEV system it must be tested at regular (normally 12 month) intervals and certificated
under the COSHH regulations. This service is available from us, or our approved testers.
Thorough examination and test should include:
-Ensuring the prescribed maintenance routines are being completed and recorded within the system logbook.
-Condition check of air mover, filters.
-Performance testing according to recommended face velocities.
-Visual check that operators are working within effective area.
-Visual check of effectiveness using, for example, smoke tubes.
Recommended face velocity is 0.5m/s RVA.
Completion of Thorough Examination and Testing should be recorded within the system logbook.
