Industrial applications place great demands on air and liquid filtration.
Our R&D team is recognized around the world for its ability
to apply materials technology to your most difficult industrial
filter media requirements. We produce a wide variety of cellulose
and cellulose-meltblown composite products with high fractional
efficiencies.
H&V's gas turbine and dust collection media are designed to
meet the rigid performance requirements of industrial pulse cleaning
and air intake filter applications. We offer a wide range of cellulose,
cellulose/polyester fiber, and polyester glass combinations. Greater
polyester reinforcement stabilizes the pleats and provides greater
moisture resistance. These grades are designed for optimal performance
in difficult environments ranging from dusty, arid areas to high
humidity, coastal areas. Many are available with fungicidal treatments,
if desired. These products have higher efficiencies at sub micron
particle sizes and are available in flat or corrugated form. Our
gas turbine and dust collection media produce strict fractional
efficiency control that extends the periods between filter maintenance.
We supply a wide range of hydraulic filtration media - from standard
mobile applications to specialized industrial liquid filtration.
Our products include the entire spectrum of filter media from cellulose,
cellulose/synthetic, meltblown, base microfiberglass, and laminated.
Filtration performance characteristics range from Beta ratios of
<4 micron(C) to 40micron(C) or higher on some pre-filtration
grades. We design media to specifically meet your needs, including
requirements for higher capacity (Hovoglas®Plus, DualPhase,
or DualLayer), lower pressure drop (Help, Meltblown), or reduced
chemical resistance using special binders. Some of our major product
lines are listed below:
Help (High Efficiency Low Pressure Drop): This media offers low
pressure drop for any desired efficiency, or higher efficiency at
comparable pressure drop. It features high yield (more pleats) due
to low caliper and no compression of media during conversion.
Hovoglas® (Base): The base product line comes in several forms.
Single-phase media contain one layer of glass with natural gradient
density for higher dust holding capacity (DHC) and low cold start
pressure drop. In the dual-phase offering, an efficiency and capacity
layer are formed at the paper machine to provide higher DHC than
the single-phase media. In dual-layer form, single-phase layers
are laminated together with a scrim for maximum flat sheet DHC.
Hovoglas (Laminated): The product line also is available in laminated
versions. Laminating a scrim adds durability and speed during pleating.
Laminating with cellulose eliminates the need for mesh with lower
pressure applications. We also provide custom laminating for use
with different processes.
Hovoglas Plus (Laminated): This next-generation product provides
improved performance over previous lamination processes. It offers
higher DHC, lower initial pressure drop, and no change in efficiency
Other hydraulic filtration media include Microglass Fiber Papers,
a lighter weight media; Meltblown (Polyester) in calendered and
uncalendered forms; and Cellulose Fiber Blends for low pressure.
