Regulatory Approval

KleenAir Systems International plc ("KleenAir" or the "Company")
KleenAir Filters win approval from Transport for London


London, September 11(KSIP):

KleenAir, a leading provider of emission control systems, has won formal approval from Transport for London ("TfL") to
supply its Free Flow™ Filters to all Heavy Goods Vehicles ("HGV") operators needing to comply with London's Low Emission
Zone ("LEZ") requirements.

Under LEZ regulations, HGV will have to meet stringent European Union emissions standards by 2008, or else pay punitive
fines when entering Greater London.  KleenAir's robust and low maintenance exhaust filters can be quickly and easily
installed and will ensure that vehicles will be fully LEZ compliant.

Chairman, Lionel Simons said:  "The Government has not only rigorously tested our equipment but has thoroughly
scrutinised the Company's quality systems and financial standing.  This approval is a hugely important step forward for
the company and means that we can now start to convert our substantial number of quotations into firm orders."

KleenAir is a global provider of customised, cost-effective pollution filters for diesel vehicles.  By significantly
reducing the harmful level of vehicle pollutants, KleenAir's innovative environmental management technology is helping
to create a greener, safer and healthier world.

Note to Editors

Free Flow™ Filter
The benefits of the Free Flow™ Filter are:
Most cost effective solution to upgrade Euro II vehicles to Euro III (LEZ 2008)
Reduces Particulate pollution by 50-70%
Easy to install - direct replacement for existing silencer
Minimum maintenance
Simple to clean (steam clean or water jet)
Longer-lasting robust metallic core
Substantially lower back-pressure than a traditional wall-flow filter
Regenerates with more frequency due to low soot loading

London's Low Emission Zone (LEZ)
From February 2008 the LEZ will apply to lorries over 12 tonnes.  From July 2008 the LEZ will also apply to lorries over
3.5 tonnes, buses and coaches.
Operators of affected lorries, buses and coaches that do not meet the LEZ standards will need to pay £200 for each
charging day they are driven in the zone.  The level of charge has been set to encourage operators to clean up their
fleets rather than incur a charge.  A penalty charge of £1,000 will apply for operators of non-compliant vehicles,
reduced to £500 if paid within 14 days.

KleenAir estimates that over 40,000 vehicles will need to upgrade their vehicles to become LEZ compliant at a cost of
over £120 million.
