- Hoodless Air Intake Series (B50, B52):
- Ideal for sheltered installations with exposed filter elements for easy inspection and pre-filter cleaning.
- Chamber Silenced Series (C10, C12) and Tube Silenced Series (D10, D12):
- Reduces equipment inlet noise by up to 50%, ensuring quieter operations.
- In-Line Filters (E20, E22) and Side Arm Housings (F20, F22):
- Versatile installation options between the inlet source and equipment.
- Perfect for indoor setups with exterior draws, eliminating the need for rooftop access.
- Exhaust Series (H20, H22):
- Effectively captures mist and smoke without significant pressure drop (ΔP) losses.
- Features a revolutionary radial fin reverse flow design for superior performance.

Safety and Convenience:
- Each housing includes a removable 304SS perforated steel safety cage to protect the housing’s throat during filter changes.
- The safety cage is designed with excess open area to prevent pressure loss, ensuring smooth airflow.
Connection Options:
- Standard Connections: Male NPT (MT) or flat face flanges (FF) matching 150# ANSI standard.
- Optional Configurations:
- Right angle base (AF) for side mounts.
- Female NPT (FT), bevel (BV), or square cut stub necks (PE) for welding.
- Custom connection sizes available upon request.
- Horizontal Mounting: Special interior element side mount support assemblies for unique installation needs.
Flange Sizing Assistance:
To match existing filter housing flanges:
- Measure a 90° arc (1/4 of the circle) over the bolts of your existing flange.
- Multiply by 4 to determine the bolt circle diameter.
- Count the number of bolts.
Compare with the provided chart for accurate sizing.
Note: Do not rely on flange OD measurements, as they can vary between suppliers.
