F5 Pocket Filters
F5 pocket filters for medium-efficiency filtration between coarse pre-filters and finer downstream stages.
Grade / Class
F5
Efficiency
Typically rated at 45% to 65% efficiency, depending on operating conditions and test standard.
Type
Pocket FilterApplications
- Used where better performance than a coarse pre-filter is required, without stepping fully into the higher F6 to F8 secondary pocket grades.
- Suitable for commercial and industrial air-handling systems needing a sensible balance between resistance, service life, and medium-efficiency filtration.
- Frequently selected as an intermediate stage ahead of finer secondary or final filtration in general HVAC installations.
Key Features
- Designed with multiple ultrasonically welded pockets to give a stable bag construction and make efficient use of the available media area.
- Offers a practical middle ground between basic pre-filtration and the finer synthetic pocket grades above it.
- Provides worthwhile dust-holding capacity in a relatively compact housing size while keeping airflow resistance workable.
- Fits applications where a straightforward medium-efficiency pocket filter is needed without overcomplicating the specification.
