The Difference Between Filters and Strainers

Filters and strainers are often treated as interchangeable, but they solve very different problems.

Using the wrong one can mean unnecessary pressure loss, higher maintenance, or equipment that is not properly protected.

In our latest article, we clearly explain:

- The real difference between filters and strainers
- When a strainer is enough, and when a filter is required
- Typical particle size ranges, mesh and micron crossover points
- How pressure drop, flow rate, and maintenance differ between the two
- Where each should be installed in an industrial system

If you are specifying new equipment, upgrading a line, or troubleshooting pressure issues, this guide helps you choose the right solution the first time.

Industrial Strainer Cleaning Procedures

Strainers do not fail suddenly. Most issues build up through rising pressure drop, restricted flow, and missed maintenance.

Our latest article sets out a clear, site-ready approach to industrial strainer cleaning, including:

- Safe isolation, venting, and depressurisation steps
- When ΔP indicates it is time to clean, not guess
- Correct cleaning methods for basket and Y strainers
- Common mistakes that damage screens and shorten service life
- How to set maintenance intervals based on real operating data

If strainers protect pumps, valves, meters, or heat exchangers in your system, this guide helps reduce unplanned shutdowns and extend equipment life.

Mesh Sizing and Perforations for Industrial Strainers

Choosing the right mesh size or perforation is one of the most common causes of pressure loss, blockages, and unnecessary maintenance in industrial systems.

Our latest article breaks it down clearly:

- When to use mesh vs perforated plate
- How mesh number and micron ratings actually relate
- What open area means for pressure drop and cleaning
- Practical starting points for pumps, valves, meters, heat exchangers, and more

If strainers are part of your system design, maintenance planning, or troubleshooting, this guide is well worth a read.
