SIDE ARM AIR & GAS FILTERS
Available Series:
- Series F20: Enameled Steel with Bolted Closure
- Series F22: 304 Stainless Steel with Bolted Closure
Overview:
Air & Gas Filtration’s Side Arm Air & Gas Filters, Series F20 and F22, are designed for efficient air and gas filtration with a unique bottom outlet connection. This orientation reduces pressure drop (ΔP) by eliminating the need for an elbow, making them both cost-effective and performance-driven. These filters are ideal for protecting compressors, blowers, turbines, and other pipeline equipment.
Key Features:
- Intake Air Flow: Up to 20,000 CFM.
- Low Pressure Drop (ΔP): Optimized design for smooth airflow.
- Safety Cages: 304SS throat safety cages included as standard.
- Bolt Seal Closure: Rated for services up to 5 psid (consult us for designs up to 15 psid or use with reciprocating compressors).
- Connection Sizes: Range from ½” to 24″.
Connection Options:
- Standard Connections: Male NPT (MT) or flat face flanges (FF) matching 150# ANSI standard.
- Optional Configurations:
- Female NPT (FT).
- Bevel (BE) or plain cut stub necks (PE) for welding.
- Custom Sizes: Increased or decreased connection sizes available upon request.
Filter Element Options:
- Standard Construction:
- Textile media elements with low ΔP, high dirt-holding capacity, and exceptional efficiency.
- Material Options:
- 304SS media support screen and/or center cores (replace “K” in part number with “N” for 304SS core and screen, or “Q” for 304SS core with epoxy-coated aluminum screen).
- Efficiency Levels:
- 10µ for general filtration.
- 4µ High Efficiency for finer particles.
- 0.3µ coalescing for removing 98% of dust, dirt, and fine mists.
- Specialized Media: Available for elevated temperatures or specific chemical resistance requirements.
Coalescing Services:
For coalescing applications, housings should be installed with reversed flow:
- Inlet flow travels to the inside of the filter element, passing through the media to the outside.
- Coalesced liquids collect in the sump area below.
Coalescing Filter Features:
- Oil & Gas Resistant Ends: Suitable for demanding environments.
- Filter Media: MicroGlass/Synthetic composite for superior performance.
- Screen Jackets: Upstream/downstream epoxy-coated screen jackets.
- Core and Shell: Perforated carbon steel core with corrosion control coating.
- Outer Foam Drain Wrap: Easily removable for non-aqueous services.
