Exhibit 10(j)
                 MET-PRO CORPORATION DIRECTOR'S RETIREMENT PLAN

     1.   PURPOSE OF THE PLAN.

          The Company  recognizes  that the Directors  have performed all duties
     ably and well, to the satisfaction and benefit of inducement to the present
     Directors  to  continue  to serve  the  Company,  and in  order to  attract
     competent individuals as eventual  replacements,  the Company believes that
     it is in its best  interests  to  provide  the  Directors  with  additional
     compensation pursuant to this Director's Retirement Plan (the "Plan").

     2.   CONTINUED SERVICE OF DIRECTOR - DIRECTOR'S FEES.

          The Company  will  continue  to pay each  Director  for such  person's
     services  Director's  fees and/or  salaries at the rates and times mutually
     agreed upon between each Director and the Company, as approved by the Board
     of Directors of the Company.

     3.   ELIGIBILITY.

          A  Director  shall  be  eligible  to  participate  in  the  Plan  upon
     completing  six (6) years of service as a Director.  At the time a Director
     becomes   eligible  to   participate   in  the  Plan,  the  Director  shall
     automatically acquire a vested right to not less than the amount and number
     of annual payments (the  "Retirement  Payments") for which such Director is
     then  eligible  under  Section 4, subject,  however,  to the  provisions of
     Section 5. Such right may not thereafter be reduced or curtailed  excepting
     as provided  elsewhere in the Plan, and shall be increased  thereafter from
     year to year pursuant to the Plan or modifications thereof.

     4.   RETIREMENT PAYMENTS.

          (a) An  eligible  retired  Director  shall be  entitled  to an  annual
     Retirement  Payment of One Thousand  Dollars  ($1,000)  times the number of
     full  years of  service  as a  Director,  up to a maximum  of Ten  Thousand
     Dollars ($10,000).  Such Retirement Payments shall continue for a period of
     years  equal to such  person's  full years of  service,  up to a maximum of
     fifteen (15)  Retirement  Payments,  subject,  however to the provisions of
     Subsection 4(d) and Section 5 hereof.

          (b) A  Director  who has  served  as Chief  Executive  Officer  of the
     Company  ("CEO")  for at  least  six (6)  years  shall  receive  additional
     Retirement  Payments of One Thousand  Dollars  ($1,000) times the number of
     full years such person has served as an Officer and/or a Director,  up to a
     maximum of Twenty Thousand  Dollars  ($20,000).  Such  Retirement  Payments
     shall be made for a period of full years equal to such  person's full years
     of service as an Officer and/or Director, but not for more than twenty (20)
     years.  However,  such payments shall  terminate  sooner upon such person's
     death or the death of such person's spouse,  whichever last occurs, subject
     to the provisions of Subsection 4(d) and Section 5 hereof.

          (c)  The   Retirement   Payments   shall  be  paid  in  equal  monthly
     installments  on the  first  day of the  month,  commencing  with the month
     immediately  following the date such participant ceases to be a Director or
     reaches age 70, whichever last occurs.

          (d) If a retired  Director dies prior to payment of all the Retirement
     Payments to which such Director is entitled,  the  surviving  spouse or, if
     there is no surviving spouse, to the Director's estate. For the purposes of
     this Section 4(d), "Director's estate" may include a living trust of which

                                      -1-
<PAGE>
     the Director was a founder, if such trust is designated as the recipient by
     the Director in writing  filed with the Company.  If payment is made to the
     Director's estate,  the unpaid Retirement  Payments shall be paid in a lump
     sum within sixty (60) days after death.  Such lump sum  Retirement  Payment
     shall be equal to ten annual Retirement Payments due pursuant to Subsection
     4(a) and ten annual Retirement  Payments under Section 4(b), if applicable,
     less the aggregate of Retirement  Payments previously made to such Director
     under each applicable  Subsection.  If more than ten (10) annual Retirement
     Payments have been made under  Subsection  4(a) and, if  applicable,  under
     Section 4(b) as well, no lump sum payment shall be due.

     5.   TERMINATION OF DIRECTOR SERVICES.

          (a)  Nothing in this Plan  shall  confer  upon  anyone the right to be
     nominated,  elected  or  re-elected  as  a  Director  or  an  Officer  upon
     expiration of such person's term. Nothing in this Plan is meant to preclude
     the eight of a majority of the Board of  Directors or the  shareholders  of
     the Company from  terminating  the services of a Director or an Officer for
     cause or otherwise.

          (b) If, before a Director's term expires,  such Director is removed or
     resigns  because of physical or mental  incapacity,  such Director shall be
     deemed to have  completed  the term for the  purposes  of  Sections 3 and 4
     hereof.  In that case,  years of service  shall be  computed to the date on
     which such person ceases to be a Director. In the case of a Director who is
     CEO but is  removed or resigns  because  of mental or  physical  incapacity
     prior to completion of six years of service as CEO, he shall be entitled to
     the additional  Retirement  Payments provided in Section 4(b), based on the
     number of years of service as CEO. In such case, service for six (6) months
     or more during the final year shall be considered a full year of service.

          (c) If the Company  should  terminate  the services of any Director by
     discharging such Director for malfeasance, dishonesty or such other similar
     bona fide cause as a majority of the Board of Directors  deems  sufficient,
     the Company shall have no future obligation to make any Retirement Payments
     whatsoever under this Plan.

          (d) In the event a Director who is a CEO is discharged or requested to
     resign by the Board of Directors  for reasons other than those set forth in
     Subsections  5(b) or 5(c),  such  person  shall  have  only the  rights  to
     Retirement Payments provided for in Section 4(a) hereof.

          (e) If a Director's  services are  terminated  at or after a Change in
     Control (as defined in Section 6 hereof), the Director shall be entitled to
     an immediate lump sum payment of the Retirement Payments then applicable to
     such  person's  status  pursuant to  Subsection  4(a) and,  if  applicable,
     Subsection  4(b). A former  Director  who has retired  prior to a Change in
     Control (or such  Director's  spouse,  if such  Director has died) shall be
     entitled to an  immediate  lump sum payment of all  Retirement  Payments to
     which such Director was entitled  under Section 4 hereof and which have not
     yet been paid.

     6.   CHANGE IN CONTROL.

          For the purposes of this Plan,  "Change of Control" shall be deemed to
     have occurred if:

          (a) Any  "person"  or "group  of  persons",  which  person or group of
     persons  are not part of present  Management  and are acting on concert (as
     the term  "person"  is used in Sections  13(d) and 14(d) of the  Securities
     Exchange Act of 1934, as amended (the "Act")) becomes the "beneficial owner
     (as defined in Rule 13d-3 promulgated under the Act) directly or indirectly
     of securities of the Company  representing  thirty (30%) percent or more of
     the combined voting power of the Company's then outstanding securities; or,

                                       -2-
<PAGE>

          (b) At any time  there  shall be a change  in the  composition  of the
     Company's  Board of Directors  resulting in a majority of such Directors as
     of the date  hereof  no  longer  constituting  such a  majority;  provided,
     however, that in making any such determination as to change in composition,
     there shall be excluded any change where the new Director was elected by or
     upon the recommendation of such present majority; or

          (c)  The   approval   by  the   stockholders   of  the  Company  of  a
     reorganization,  merger or  consolidation,  in each case,  with  respect to
     which persons who were  stockholders  of the Company  immediately  prior to
     such   reorganization,   merger  or  consolidation   do  not,   immediately
     thereafter,  own more than fifty (50%) percent of the combined voting power
     of the  reorganized,  merged or  consolidated  Company's  then  outstanding
     securities  entitled to vote generally in the election of directors or with
     respect to a liquidation  or  dissolution of the Company or the sale of all
     or substantially all or the Company's assets.

     7.   NO OBLIGATION TO MAINTAIN RESERVES.

          The Company intends to execute an agreement with a Trustee (the "Trust
     Agreement")  to hold,  invest  and  disburse  funds set aside for  payments
     required under the Plan. However, contributions to the Trust by the Company
     shall be in the discretion of the Board of Directors.  Nothing in this Plan
     shall create an obligation  on the  Company's  part to set aside or earmark
     any monies or other assets specifically for the purposes of this Plan or to
     pay any  specified  amount to the Trust.  To the extent  that assets of the
     Trust are in sufficient to meet the Company's  obligations  under the Plan,
     such obligations will be paid out of the general funds of the Company.

     8.   UNSECURED CREDITOR'S STATUS AS TO PLAN ASSETS.

          All assets held in the Trust  created  with respect to this Plan shall
     be and remain subject to the claims of unsecured  general  creditors of the
     Company  under  federal  and state law in the  event of  insolvency  of the
     Company, as defined in Section 3(a) of the Trust Agreement.

     9.   ADMINISTRATION AND INTERPRETATION OF THE PLAN.

          (a) This document,  the Trust Agreement  executed by the Company,  all
     agreements  and awards  executed by the Company and all  amendments to such
     documents shall be deemed Plan Documents.

          (b) The  Board of  Directors  shall  administer  the  Plan,  including
     without limitation:  (i) Determination of amounts and duration of payments;
     (ii)  Construing  the Plan  Documents and (iii)  Determining  procedures of
     implementing and administering the Plan.

          (c) The Plan Documents shall be interpreted and administered under and
     governed by the laws of the Commonwealth of Pennsylvania.
