AAF Flanders VariCel II Bag Filters | High-Efficiency Pocket

AAF Flanders VariCel II Bag Filters

VariCel II is AAF Flanders' high-capacity extended-surface bag filter — a different beast from the rigid VariCel box filter. Where the rigid VariCel uses a supported pleat pack in a hard frame, VariCel II uses self-supporting fabric pockets that inflate under airflow to maximize media area in a compact footprint. The result is a high-MERV commercial bag filter with very high dust-holding capacity and very low pressure drop.

VariCel II Specifications

• MERV 11, MERV 13, MERV 14, MERV 15 efficiency options
• 4-pocket and 6-pocket configurations for various airflow requirements
• Single-header and no-header frame styles — for both sliding rack and side-access housing systems
• Standard depths of 12″ and 22″ for extended service life
• Engineered drainage — sloped pocket bottoms shed accumulated moisture
• UL 900 Classified
• Tested per ASHRAE 52.2

Where VariCel II Fits

• Commercial AHUs with side-access bag filter housings
• Pharmaceutical pre-filtration upstream of HEPA
• Hospital MAUs requiring MERV 13–14 baseline filtration
• Manufacturing facilities with high-dust loading and long service intervals
• Government and federal facilities — Section 889 compliant

VariCel II vs. VariCel (Box) — Which to Choose

Both are high-MERV commercial AAF filters, but they fit different housing types. VariCel II bag filters are for side-access housing — the bag inflates into the airflow with the filter face flush to the rack. VariCel rigid box filters are for front-load housing with full-depth (6″ or 12″) supported cells. Send us your existing filter dimensions and we'll match the right one.
