                        Lease of larger factory premises


Porvair to expand manufacturing to meet demand. Announces start of production of
                             key aviation project.


Porvair today announces that following continued strong growth in its aviation
filtration business it has signed a lease to acquire larger premises in Fareham,
Hampshire. The new factory provides 65,000 square feet of modern factory and
office space and will ease recent capacity issues.


The additional space is required to support aerospace sales, which grew 21% in
2006 and are anticipated to grow through 2007 and into 2008.


Part of this growth will be from deliveries of the fuel tank inerting filters
for Boeing aircraft that are expected to increase throughout 2008.


Ben Stocks, CEO of Porvair plc, said:

'This is one of a number of planned investments in Microfiltrex, which continues
to perform strongly. Our new premises will improve production flow and enable
further growth. To have started production of the complex fuel tank inerting
filter is a big step forward. The group continues to perform well and trading is
in line with management's expectations'
