Applications
The ULPA Filter range are usually used within Cleanrooms
for high end micro electronic applications.
ULPA Filters are usually
associated with ISO Class 3 of ISO 14644.
The ULPA filter will usually be combined with a liquid
seal channel sealing system rather than the conventional closed cell
gaskets.
Description
ULPA filters consist of a coated graduated continuously
spun glass filament in a pad form, contained within either a rigid
cardboard casing, or a cardboard frame with perforates cap-punch grids.
Stiffening bars can be provided if required.
Also a scrim backing can be supplied on the outlet face for special
applications.
Our method of manufacture for this style of filter utilises modern
hot melt adhesive techniques, which produce an extremely rigid and
robust product.
