               KleennAir wins order from City of London Corporation

2 August 2007

KleenAir  Systems  International plc, a leading provider  of  vehicle  pollution
filters,  today  announces a pilot contract to supply systems  to  the  City  of
London Corporation for its refuse collection vehicles (RCVs).

This  is KleenAir's first local authority contract and the systems supplied will
be  evaluated  over  a  3-6  month period after  which  further  orders  may  be
anticipated.  The systems to be supplied include the Free Flow™ Filter  and  the
Sintered  Metal  Filter (SMF™).  Both filters enable vehicles to  meet  specific
Euro   standards,  with  the  SMF  in  particular  meeting  the  more  stringent
requirements for the LEZ (Low Emissions Zone) in 2012.

Lionel  Simons, Chairman of KleenAir, said: "We are delighted to be providing  a
service which will start to clean up the heart of the City.  The City of  London
Corporation  has  been  at the forefront of environmental  protection  for  many
years,  and  encourages  others to do the same with its  innovative  Clean  City
Awards  Scheme.  Once again they're leading the way with the use of our cutting-
edge  technology to reduce vehicle emissions.  We expect other Local Authorities
will soon follow their lead and we look forward to a more extensive, longer term
relationship with the City of London Corporation in the years ahead."

for  diesel  vehicles.  By significantly reducing the harmful level  of  vehicle
pollutants, KleenAir's innovative environmental management technology is helping
