Air Filters and Chemical Filtration
Separator HEPA Filter
A traditional full-depth HEPA cell that uses corrugated aluminum separators to hold broad microglass pleats open under demanding airflow.
- Corrugated Aluminum Separators
- Deep-Pleat Media Pack
- Rigid Full-Depth Cell
- High Dust Capacity
Product Introduction
The separator HEPA filter forms water-resistant microglass media into deep pleats and places corrugated aluminum sheets between adjacent faces. Each separator creates a continuous airflow channel while adding stiffness across the full pack depth. The assembled pack is potted on all four sides into galvanized steel, stainless steel or anodized-aluminum cell sides, then protected by expanded-metal faceguards. Its robust construction is suited to built-up filter banks, containment housings and critical air handlers where the filter must tolerate handling, fan cycling and elevated final resistance.
Key Features
A deeply potted pack-to-frame bond resists bypass and movement under pressure loading.
Rigid metal cell sides and faceguards protect both media faces during installation and removal.
The full-depth pack offers substantial dust storage for long-duty central HVAC service.
Customer Product Concerns
Deep-pleat HEPA filters must maintain uniform channels and mechanical integrity as accumulated dust raises the pressure load.
Broad HEPA pleats collapse together and block large sections of media.Corrugated aluminum separators support each pleat face and preserve an open path through the complete depth.
A heavy media pack shifts inside the cell during transport or fan starts.Four-sided polyurethane potting anchors the pack to rigid metal cell sides.
Exposed microglass pleats are punctured during filter-bank servicing.Upstream and downstream expanded-metal faceguards keep hands and rack hardware away from the media.
A distorted full-size filter cannot compress evenly against the bank gasket.Reinforced cell sides and square corner joints retain a flat sealing plane.
Typical Applications
Critical HVAC final-filter banksPharmaceutical exhaust and supply systemsHospital isolation ventilationContainment and bag-in/bag-out housingsHigh-purity industrial air systems
