Hi-Flo
The Camfil Farr Hi-Flo® offers high efficiency ASHRAE grade filtration to address today's indoor air quality problems. The Hi-Flo can remove contaminants such as fumes, smoke, bacteria, fungi, and virus-bearing droplet nuclei. The Hi-Flo is also the filter of choice for the removal of nuisance contaminants such as pollens, paper dust, and other atmospheric impurities.
Hi-Flos are available in the following efficiencies:
- MERV 9(45%), MERV 11(65%), MERV 13(85%), MERV 14(95%)
High Lofted Air Laid Media
The Camfil Farr Hi-Flo incorporates high lofted air laid micro fiber glass media to ensure reliable efficiency throughout the life of the filter. Its small fiber diameter and uniform lofting results in consistent sub-micron particle capture and a low resistance to airflow throughout the life of the filter. A synthetic micro mesh media backing ensures media protection and support in turbulent or varying airflows. The Hi-Flo's particle capture performance and filter configuration are unaffected by dust loading and/or humidity.
Controlled Media Spacing
Camfil Farr is the only manufacturer to offer controlled media spacing to minimize pocket-to-pocket contact, ensure uniform airflow and allow full utilization of the media area. The effect results in the lowest life cycle product cost for your facility. Your selection of the length and number of pockets should be based upon the required airflow through the system. Typical 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, through the use of continuous thread filaments, helps keep as many as 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 an even media velocity for uniform dust loading and a maintained low pressure drop.
The benefits include:
- Increased filter life
- Reduced maintenance costs
- Minimized fan horsepower requirements
- Reduced energy expenditures.
Stitch Sealant & Adhesive Bonding
Camfil Farr completely seals pocket stitching to eliminate the possibility of air leakage through the stitching penetrations. This unique sealant maintains a flexibility that is unaffected by varying airflows. The media is also bonded around the pocket retainers to ensure a strong pocket-toretainer seal and minimizes potential for pocket failure.
Sure-Clench® Crimp
Each galvanized steel pocket retainer is fastened with Camfil Farr's exclusive Sure-Clench crimp, creating a positive lock between pockets and eliminating the possibility of air bypass. The pocket retainers include rolled edges to prevent damage to the media area and minimize sharp edges that may create a hazard to filter installers. Four retainer clips assist in securing pocket retainers to the header frame.
Galvanized Steel Header
A box-channel header, of one-piece corrosion resistant galvanized steel, includes rolled edges to prevent damage to the filter media. When combined with the Sure-Clench Crimp and galvanized pocket retainers, a rigid and durable assembly is created. Camfil Farr manufactures the Hi-Flo to be capable of withstanding up to 5.0" w.g. in normal HVAC application.
Leak-Free Filter Performance
Every Camfil Farr Hi-Flo includes 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.
Performance
Hi-Flo filters are manufactured from microfine glass fibers for consistent and long-term high efficiency performance. They are available in fractional efficiencies from 40% to 95% on particles as small as 0.3 micron in size. MERV values range from 9 to 14 when evaluated under ASHRAE Standard 52.2.
Configurations for any Application
Camfil Farr Hi-Flos are available in a variety of configurations to suit your air movement requirements. Common configurations include from 3 to 12 pockets, depths of 15" to 36", and up to 129 square feet of effective media area.
When selecting a Hi-Flo for your system, you should select a filter with the greatest effective media area within the airflow parameters and space limitations for your system. This will ensure a long filter life and a consistent low resistance to airflow over the life of the filter. Fewer filter changes will be required, thus reducing replacement, labor and disposal costs. An additional benefit includes reduced system horsepower requirements, thus lowering the facility's energy expenditure.
Lowest Life Cycle Cost
All of these components combine for the lowest life cycle cost, the lowest average pressure drop (energy savings), and consistent high efficiency particulate filtration throughout the life of the filter.
