For Flat Bank & “V” Bank Filter Arrangements
Airsan Type AH filter retainers are engineered for secure, reliable installation of air filters in flat bank and “V” bank configurations. Designed for flexibility and durability, these retainers can be built up to virtually any height or width by progressively adding additional units—making them ideal for custom or large-scale air handling systems.
Durable Construction for Heavy-Duty Applications
Each Type AH retainer is built for long-term performance in industrial, commercial, and severe-duty environments.
Standard Construction
- 18-gauge galvanized steel frame
- Spot-welded corner gussets for added structural strength
- Two positive retaining clips to securely lock filters in place
This rugged construction maintains stability under continuous airflow, vibration, and system pressure changes.
Air-Tight Sealing
To prevent system contamination and maintain proper airflow performance:
- Gaskets around the inner perimeter create a tight seal
- Eliminates bypass of unfiltered air, protecting downstream components
- Ensures maximum filtration efficiency from any installed filter type
Size & Adaptability
Standard Type AH retainers are available in:
- 2″ nominal thickness
- 4″ nominal thickness
The 2″ retainer can be adapted for 1″ filters with the addition of a Z-111S clip, offering system design flexibility.
Because retainers can be combined modularly, Airsan AH units can accommodate virtually any system opening size.
Material Options
To meet a variety of environmental and system requirements:
- Galvanized steel (standard)
- Aluminum
- Stainless steel (Type AHS)
Type AHS stainless steel retainers are manufactured from 20-gauge, Type 304 stainless steel and offered in standard 2″ dimensions—ideal for corrosive or marine environments.
