Extended Surface Air Filter

The Camfil Farr Hi-Flo® is an extended surface air
filter providing high-efficiency ASHRAE grade filtration.
The Hi-Flo extended surface air filter removes fumes,
smoke, bacteria, fungi and virus-bearing droplet nuclei.
It is the extended surface filter of choice for nuisance
contaminants such as pollens, paper dust and other
atmospheric impurities.

The Hi-Flo air filter incorporates high lofted air-laid
microfibre glass media to ensure reliable efficiency
throughout the life of the filter. Equipped with a high
quality filter material, with small fiber diameter and
uniform lofting, it guarantees consistent and reliable
submicron particle capture throughout its service life.
Synthetic micro mesh media backing ensures medium
protection and support in turbulent or varying air flows. 

Hi-Flo’s particle capture performance and filter
configuration are unaffected by dust loading
and humidity. 

The Advantage of Controlled Media Spacing

Camfil Farr is the only manufacturer to provide
controlled media spacing to minimize pocket-to-pocket
contact, ensure uniform airflow and allow full use of
the media.  This results in lowest life cycle product cost
for your facility.  Your selection of the length and
number of pockets is based on the required airflow –
contact your Camfil Farr representative for an evaluation. 

Traditional bag filters allow pocket-to-pocket contact,
causing loss of effective media area, non-uniform
airflow and an excessive pressure drop over the life
of the filter. Camfil Farr’s variable length pocket stitching,
and continuous thread filaments, keeps up to 12 individual
pockets in a perfectly aligned V-shaped configuration.
This tapered pocket effect equalizes the media entrance
and exiting areas. Air travels evenly through the filter at
a uniform media velocity for optimum dust-loading and
a maintained low pressure drop. As a result:

• Filter life is increased.
• Maintenance costs are lowered.
• Fan horsepower requirements are minimized.
• Energy expenditures are reduced.

Leak-Free Filter Performance

Every Camfil Farr Hi-Flo has a gasket on the vertical
edge of the filter header. In a side-access housing,
filters are mated header-to-header. The gasket
prevents air bypass and ensures that the air filter
will clean all of the air moving through the system.
