FAQ

 

Q1: How do I choose the right coalescing filter element for my fluid?

 

A1: Consider the following:

• ► Fluid type and goal – For water removal from fuel/oil, choose a hydrophilic coalescer. For oil removal from water, choose an oleophilic coalescer.

• ► Viscosity – High‑viscosity fluids require larger pore sizes to avoid excessive ΔP.

• ► Temperature and chemical compatibility – High‑temperature or corrosive fluids need stainless steel fiber or PTFE media.

• ► Flow rating – The element’s rated flow must be ≥ the system’s maximum flow, with margin (e.g., 20%).

• ► Pre‑filtration – Install a 3–5 µm absolute pre‑filter upstream to protect the coalescer from solids.
   

Q2: What materials are coalescing elements made from, and when to use each?
 

A2: Common materials and their typical applications:

• ♦ Glass fiber – High efficiency (0.1 µm), excellent hydrophilic performance. Suitable for most fuel and light oil dehydration. Standard choice.

• ♦ Polyester fiber – Good chemical compatibility with many solvents and wastewater streams.

• ♦ Stainless steel fiber – For high temperature (>100 °C / 212 °F), high pressure, or corrosive environments. Requires special surface treatment for hydrophilicity (more costly).
   

Q3: How often should coalescing filter elements be replaced?

 

A3: Replacement depends on three indicators:

1. • Differential pressure – Replace when ΔP reaches the manufacturer’s maximum (typically 0.15 MPa / 22 psi).

2. • Water removal performance – Replace when downstream water content consistently exceeds the target (e.g., >15 ppm for jet fuel).

3. • Calendar time – Even without high ΔP, replace coalescing elements every 6–12 months. Separating elements can last longer, but replace them together if the system is critical.
    

Q4: What is the correct procedure for replacing coalescing filter elements?

A4: Follow these steps:

1. ⇒ Depressurise – Close upstream/downstream valves and vent the housing to zero pressure.

2. ⇒ Remove old element – Carefully remove the spent coalescing element. Inspect seals and housing interior.

3. ⇒ Install new element – Ensure the new coalescing element is installed in the correct orientation (usually inside-out flow). Check that all O‑rings are undamaged and properly seated.

4. ⇒ Flush system – Before returning to service, flush briefly to remove any installation debris.

5. ⇒ Monitor – Restart slowly and verify ΔP and water removal performance.
