                                Trading Statement

24 September 2007

KleenAir  Systems  International plc ("KleenAir" or the  "Company"),  a  leading
provider of emission control systems, has seen a significant increase in  orders
in  the  week since receiving approval from Transport for London (TfL) to supply
its  Free Flow™ Filters to all HGV operators needing to comply with London's Low
Emission Zone (LEZ) requirements.

Under  LEZ  regulations, HGVs will have to meet stringent EU 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.  KleenAir's pollution-
reducing  filters  are  the  only ones listed on  TfL's  website  as  being  PFF
certified.

Chairman, Lionel Simons said:  "Within a week of receiving TfL approval, we have
received  over  £100k  of orders and we are now in the  process  of  working  to
convert over £1.25m of quotations into new business."

Note to Editors

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.

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.
