BF Series
Flanged High-Flow Air Filter

The Omega Air BF Series is engineered for large-scale compressed air installations requiring flanged connections and very high flow rates. Covering DN80 to DN300 flanged ports and flow capacities up to 31,400 Nm³/h, the BF is the definitive choice for central compressor houses, large-bore main headers and industrial plant-wide distribution systems.

Filter Grades for BF Series

All five Omega Air filter grades are available in the BF Series, enabling complete filtration trains to be built using a single flanged housing family even at very high flow rates.

P
General Particulate
3 µm bulk particulate, rust, pipe scale removal on large main headers.
R
Fine Particulate
1 µm fine dust and sub-micron solids ahead of coalescing stages.
M
Coalescing
0.1 µm oil aerosol coalescing. Residual oil ≤0.1 mg/m³ at high flow rates.
S
High-Efficiency Coalescing
0.01 µm high-efficiency. Residual oil ≤0.01 mg/m³ for critical large-scale processes.
ACS
Activated Carbon
Oil vapour and odour removal for large-volume food, beverage and packaging lines.
Where It's Used

Typical Applications

🏭
Central Compressor Houses

Primary filtration immediately downstream of large multi-stage compressors before plant-wide distribution headers.

⚙️
Large Industrial Plants

Steel mills, petrochemical plants, cement works and power stations where main ring-main flows exceed 1,000 Nm³/h.

🚂
Locomotive & Rail

Depot main compressed air systems protecting braking and control equipment across entire maintenance yards.

🛢️
Oil & Gas

Instrument air and utility air skids on offshore platforms and onshore facilities with high-flow flange-connected piping.

🌾
Large Food Processing

High-volume food and beverage factories where flanged main headers feed multiple production lines simultaneously.

💧
Water Treatment

Instrument and aeration air in municipal water and wastewater plants where flanged PN16 connections are standard.
