Definition
“LEV (Local Exhaust Ventilation) is an engineering control system to reduce exposures
to airborne contaminants such as dust, mist, fume, vapour, or gas in a workplace”
(HSE 2011).
Statutory Examination and Testing
Every LEV system requires statutory thorough examination and testing by a competent person under the
Control of Substances Hazardous to Health (COSHH) Regulations: 2002 (amended 2004). The maximum
time between tests of LEV systems is 14 months. In practice this is normally taken to mean annually.
The examiner should:
• Carry out a thorough external examination of all parts of the system for damage, wear and tear.
• Measure the air velocities at suitable test points indicated in the system documentation.
• Measure static pressure at suitable test points indicated in the system documentation.
• Observe processes and sources and assess how effective the LEV is at controlling operators’ exposure.
When testing hoods, the examiner will attach a test label to each hood tested. A red ‘fail’ label could be
attached for the following reasons:
• No airflow.
• Failure of the hood to intercept or contain the contaminant cloud.
• The hood capture zone does not encompass the working zone.
The examiner will compare the test information against the original commissioning report, or previous
test reports, to determine system effectiveness. A full report for each LEV system will be produced by the
examiner. If required, the LEV report will highlight any minor adjustments or repairs required to make the
LEV system effective.
Filtermist -JNJUFE is able to provide LEV testing to HSG258 standards. For a quotation, contactthe
Filtermist Sales Department on 01952 290500.

Filtermist as an LEV System
Filtermist units are designed for the control of aerosol mists, namely those generated by machining operations
that use either soluble or neat oil coolants. Other applications include component washing machines and EDM
machines. Due to the aggressive nature of the fluid, it is recommended that only stainless-steel versions are used
on component washing machine applications.
Filtermist units are NOT designed to work on welding fume or dry dust applications. Please contact the Filtermist
Technical Support Department (01952 290500) if further advice is required regarding the suitability of any
application.
Filtermist units are designed for use with the majority of machine tools, both enclosed and open, and offer high
levels of filtration with minimal service requirements. Enclosed machines are covered by changing the air within
the enclosure between 6 and 10 times per minute, depending on application, whilst ensuring gaps within the
enclosure are kept under a negative pressure. Open machines are usually covered by hoods positioned to capture
and extract mists generated by the machining process.
Generally a capture velocity between 30 – 45 m/min is needed at the source of the contaminant. Typical
installations are described later in this manual. Bespoke installations are also available.
Operation
Filtermist units are specifically designed to separate aerosol particles, usually oil mist, from the air, including oil
and coolant mist and steam generated in parts washing process. A perforated steel drum, open at one end, is
directly driven by a 3-phase electric motor. Four vanes within the drum generate suction which draws aerosols
into the drum. Here the aerosols are impacted by the vanes at velocities in excess of 50 metres per second. The
aerosol particles are forced to collide and coalesce before being driven by centrifugal force against the inner
surface of the units casing. A drainage point ensures that the liquid is drained away under pressure. Cleaned air
is returned to the workshop.
Four pads are fitted between the drum vanes to minimise noise levels and prevent the possibility of liquid
fragmentation. As the drum speed is constant, the separation phase of the process remains constant ensuring
high levels of filtration are maintained.
Efficiency
Aerosol particles are generally considered to be in the 0.2 – 5.0 micron range. Within this range are particles
which provide a potential hazard to health. Particles above 3.5 micron are usually filtered out by the natural
filters in the human system. Particles of 0.3 micron and below are thought to be exhaled.
This leaves an important range of particles that can be retained within the body and which should be removed
from the air before they are inhaled
Filtermist units provide high filtration efficiencies across this critical range. Efficiencies of 98% have been shown
in independent tests carried out on typical oil mist applications.
Greater efficiencies can be achieved using a high-efficiency secondary filter (afterfilter) on the exhaust side of the
unit. UK customers have an afterfilter supplied as additional standard equipment along with each unit (excluding
those units to be used on parts washing machines).

Please note that units intended for use in countries outside Britain may require changes to the
motor settings. Please contact Filtermist -JNJUFE (01952 290500) for advice and technical support.
To ensure the continued performance of your Filtermist system, there is an integrated log book that the operator
must complete. The forms included in this book should be used to record these checks, together with comments
on any corrective action. Also a section for regular maintenance and unplanned repair work should be completed
and is included in the log book. Any failure that is found should be reported to the person responsible for the
maintenance of the system. The log book can be found from page 21 in this manual. It is important that these
records are kept up to date to provide evidence that the system is following the HSE guidelines and that it is
operating correctly.

Installation
A Filtermist unit is normally sited either on (e.g. Fig.1) or close to the application, mounted on a stand (e.g.
Fig.2) and therefore installation is straightforward requiring minimal ductwork. Filtermist units are light,
require minimal floor space and can be installed in a wide variety of ways. A comprehensive library of existing
installations is held by the company and can be used to demonstrate typical installations on most machine tools
and applications.
Mounting the Unit
The following are typical installations and cover the majority of applications. For more advice on these or other
installation methods please contact your local supplier.
Always try to position the extraction point as far as practically possible from the cutting area of the machine and
so that mist is drawn away from the operator’s working area. On installation always take into account access and
space requirements for service and maintenance of the unit, including consideration of local health and safety
regulations. For ease of access, where possible, the unit should be positioned between 1040mm and 1370mm
above the working level (providing the efficiency of the unit isn’t compromised).

Safety Information
Isolation from any power supply shall either be visible (visible break in the power supply circuits) or the isolation
device is actuated to the off position and physically locked off.
 The unit must not be operated without the case fitted.
 At least  seconds must be allowed for the inner drum to stop rotating before the case is removed.
 Oil leaks can be a hazard. The complete Filtermist system should be checked regularly for possible oil leaks.
Daily visual checks of both unit and extraction duct are recommended.
 Contact with oils, coolants etc. can cause skin disorders. Avoid contact with skin and eyes and wear PVC,
neo prene or nitrile gloves, safety glasses and overalls when cleaning or working on the filter.
 The unit to be used on wet applications only, e.g. Oil, emulsion, coolant or steam.
 The unit is not to be used on flammable, explosive, corrosive or dry applications, e.g dust, smoke, acid.
 The unit is intended for indoor use only.
Daily visual checks of both unit and extraction duct are recommended.
Ensure that the recommended schedules of checks, as detailed in the accompanying Log Book, are followed.
General Information
Filtermist units remove and separate contaminants by centrifugal impaction, forcing aerosols to coalesce into
larger droplets and removing them from the airstream. High levels of filtration and constant efficiency make this
method of separation ideal for machining applications using coolants.
Recovered oil can be returned to the machine tool or a separate container, whilst the cleaned air is exhausted
back into the work area. Collection of contaminated air should be as close as possible to its source so installation
of a Filtermist unit will usually be directly on, or very close to, the machine tool, simplifying any installation
requirements.
Filtermist unit are available in a comprehensive range of air volumes suitable for a wide range of machine tools.
Some simple guidelines need to be followed to ensure trouble free installation of each unit.
• On enclosed machine applications, the extraction point should be positioned as far as practically possible
from the cutting area of the machine. This will prevent oil droplets being drawn up into the unit and possibly
overloading the unit. It will also prevent swarf being drawn into the inlet grille which over time will cause a
reduction in air flow and therefore extraction.
• The extraction point should also be positioned so that mist is drawn away from the operators working area.
Installation Information

6
Ducting runs should be as short as possible (e.g. Fig.3). U-bends should be avoided as these will encourage oil to
collect, reduce airflow and become an area for potential leaks. Where U-bends are unavoidable, suitable drain-
age points should be provided (e.g. Fig.4).
• The oil return tube from the Filtermist unit should be straight with smooth bends – no kinks - and unrestricted
(e.g. Fig.5). The end of the tube must not be submerged as this will prevent oil from the unit being discharged.
• Fishtail hoods should be in a fixed position so as to ensure that mist produced during the process is drawn
away from the point of generation and into the hood. In some cases, more than one fishtail hood will be
required (e.g. Fig.6).

Airflow Indicator
HSE guidelines recommend that Airflow Indicators are fitted to provide the machine operator with a visual
indication that the extraction system is operating effectively. Please contact the Filtermist Sales Department
(01952 290500) for details of this optional equipment.
The FMonitor is a monitoring device that measures airflow and time to indicate when the filtermist unit needs
servicing. An additional sensor can be fitted to also monitor temperature and vibration. The monitor can be set
to suit particular applications.
The monitor uses a traffic light system of coloured LED lights to show the operating status of the unit. The
monitor is supplied with additional output source should an extra indicator be required.
