Dated: 13 April 2007

                         KleenAir Systems International
                          (`KleenAir' or the `Company')

                   Director's Dealing and Loan Back of Monies

The  Company has today been informed that Bramley Limited, ("Bramley") a company
owned  by  a  discretionary trust of which Lionel Simons, the  Chairman  of  the
Company,  and his family, are potential beneficiaries, sold 882,353 Ordinary  1p
shares  at 17p per share on 12 April 2005.  The sale was made through the market
by  Falcon Securities, the Company's broker. The gross proceeds of this disposal
are £150,000.

Bramley has in turn agreed to make a loan to the Company of £150,025 by way of a
loan  note subscription (the "Loan Note").  These funds will be used to  provide
working  capital  for  received orders, and Bramley is in discussions  with  the
Company  about  making  available  additional  facilities.  The  Loan  Note   is
convertible, at the option of either Bramley or the Company, at a price  of  17p
per  share,  equivalent to a total of 882,500 Ordinary 1p shares.  A  resolution
will be put before shareholders at the Company's next Annual General Meeting  to
give  the  Directors powers to allot sufficient new Ordinary 1p  shares  in  the
Company to allow for the full conversion of the loan note.  If the Loan Note  is
not  converted,  it will be due for redemption, at par, on 31 March  2010.   The
Loan  Note is unsecured and carries an interest rate equivalent to the base rate
of  Barclays Bank Plc, accruing on a daily basis and compounded annually  on  22
March each year until maturity.

Following   the   disposal,  Bramley  will  hold  3,117,647   Ordinary   Shares,
representing 15.74% of the voting rights of the Company.  Lionel Simons will now
have  beneficial interests in a total of 4,117,647 Ordinary Shares, representing
20.79% of the voting rights of the Company.
