Industrial Filter Solutions

Industrial filters are used to remove unwanted particles or contaminants from liquids, gases, or air during industrial processes. They help protect equipment, maintain product quality, and ensure compliance with environmental or hygiene standards. Typically we are removing particulate between 100 and 5 micron in varying degrees of loading.

Common types include:

• Depth filters – for removing solids from process liquids
• HEPA filters – for improving air quality in enclosed environments
• Coalescing filters – for removing particulate and liquid contaminants in gas streams

Each type is chosen based on the application, flow rate, and required level of filtration.

You’ll need to consider:

• Contaminant type and size
• Level of contamination
• Flow rate and available operating pressure
• Clean differential pressure to be used for sizing
• Chemical compatibility and exposure times
• Operating temperature

Consulting a filtration specialist ensures you get the best filter choice for your application. 

The micron rating tells you the size of particles the filter can remove. For example, a 5-micron filter removes particles 5 microns and larger. 

Lower ratings mean finer filtration and shorter service life. Therefore always choose the optimum micron rating to ensure protection, but offer the longest possible service life.

This depends on your system, contaminant load, and pressure drop across the filter. Regular monitoring of differential pressure across filter will help you maximise the service life of your filter.

Typically filters are changed out when their differential pressure reaches somewhere between 2 (30 psi) to 2.5 bar (37 psi).

The majority of filters are single use. However there are self-cleaning filters and basket/screen filters that can be cleaned and reused. However they only work effectively at higher micron ratings, say 30 micron and above, and are often followed by a guard filter using a single use filter to ensure liquid quality.

Factors include:

• Correct media selection
• Maintenance and replacement intervals
• Proper installation
• Pressure and flow consistency

Watch for sharp increase in pressure drop and short filter life. This may indicate that the filter media isn’t suitable for your particle load or that the loading has changed for some reason upstream. This can indicate a possible need to change filter type or the upstream issue may be resolved and no change is required.

Install differential pressure gauges before and after each housing. Uneven readings can suggest flow imbalance or bypassing, especially in parallel configurations.

Yes, if housings accept standard lengths and end cap configurations. However, check for compatibility in terms of pressure drop, chemical resistance, and flow rate requirements before any change is made.

If you need reliable, tested particle retention — particularly in pharma or high-purity applications — absolute-rated filters are predictable. They’re often worth the upgrade for downstream protection or final filtration stages.
