VariCel VXL are lightweight compact
filters designed for use in industrial and
commercial HVAC installations.
Available in the EN779 classification
range F6 - F9, their rigid design and
pleated media pack with thermoplastic
separators ensure they deliver the desired
air quality when used in variable air
volume systems and subjected to repeated
fan shutdown, high relative humidity and
intermittent exposure to water.
A BioCel VXL is available as H10 to
EN1822.
Due to their 5000m3
/h capacity,
VariCel VXL offer many cost saving
benefits. In new installations fewer filters
are needed to handle the same volume of
air compared to filters of the same size
with a lower capacity. Fewer filters mean
less installation space for the filtration
system. They can also be used in existing
systems to increase the air capacity.
VariCel VXL display low media resistance
and have a high dust holding capacity and
long service life.
Media
VariCel VXL media is water resistant
and can withstand exposure to free
moisture in the airstream. When wet
there will be a temporary rise in
resistance, which quickly returns to
normal as soon as the moisture
evaporates. The design ensures a full
depth loading of dirt across the entire
surface of the filter media
Construction
The header and cell sides provide a
sturdy construction that resist damage
during shipping, handling and
operation. The entire polystyrene
construction is fully incinerable.
Separators
The thermoplastic separators maintain
uniform spacing between
pleats to allow optimal flow of air
into and through the filter.
They also ensure large effective
media area for low resistance and high
dust holding capacity.
Operating Temperature
VariCel VXL filters can operate at
temperatures up to 80°C.
VariCel VXL is also available with
Intersept biostatic treatment.

1) Width and height are interchangeable, pleats can be either vertical or horizontal without affecting performance.
2) All performance data based on EN779:2002 / EN1822.
3) Recommended maximum value. Filters can be operated to a lower final resistance without materially effecting filter efficiency.
4) Filters are also available in size 490 x 592 x 292 mm and 287 x 592 x 292 mm.
