Trading update

KleenAir Systems International plc today announces a trading update for the year
ended 30 September 2008.

Sales  for  the second half year more than doubled in comparison with the  first
half,  with  revenue  for  the year in excess of £800,000.  Gross  margins  have
improved  and  additional  contribution has  resulted  in  a  reduction  in  the
estimated  operating  loss for the second half, before  any  potential  year-end
provisioning  and audit adjustments.  Cash management has been assisted  by  new
factoring  arrangements  with Bibby Financial Services.   Order  intake  on  the
Company's  diesel  particulate filter product (targeted at  owners  of  vehicles
operating  in  the London Low Emission Zone) was, as expected, sharply  down  in
September and the Company expects a slow fiscal first quarter, with first  sales
of  a  new Diesel Saving Module and new filter products, to be launched  at  the
upcoming  Bus Show at the NEC in Birmingham next month, unlikely in  significant
volumes before 2009.
