Reading the Pressure-Drop Curve: A Practical Guide for Plant Engineers

For plant engineers, a filter's pressure-drop curve is more useful than a single pressure-drop figure. It shows how resistance changes as airflow increases and provides a practical way to evaluate whether a filter is correctly sized for the operating point.

Altair Equivalent Filters: The Complete EPC Buyer's Guide

Selecting Altair equivalent filters for an EPC project is not simply a matter of finding a filter with the same dimensions or matching an old Parker/Altair part number. The replacement must be evaluated against the intake system, airflow, pressure drop, filtration efficiency, media construction, sealing arrangement and operating environment.

Gas Turbine Air Filtration: How Coastal Conditions Change the Specification

Coalescer Panel Filters Explained: What They Do and Why Your Turbine Needs Them

A coalescer panel filter removes water, salt mist and oil droplets from the air before it reaches your gas turbine. It sits in the middle of a multi-stage filter system, between the coarse pre-filter and the fine final filter. Without it, moisture and salt combine with dust and stick to the compressor blades. This guide explains how coalescer panels work, where they fit in your filter house, and how to pick the right one for your site. Find your equivalent filter below and get a fast, verified match.

UKAS Accredited Testing for Industrial Air Filter Performance

Learn how UKAS accredited testing supports industrial air filter performance evaluation, including efficiency, pressure drop, airflow, test scope and measurement.

Power Gen Filtration: Protecting Turbine Output at Scale

Power plants run turbines for thousands of hours a year, which means even a small drop in filtration performance adds up fast. This guide explains what makes power generation filtration different, which filter stages matter most, and how to match the right products to your plant type. Talk to a filtration engineer today and make sure your intake system is built to protect output over the long run, not just the next few months.

High-Efficiency Pocket Filters: HEPA, HVX & HVL Guide

High-efficiency pocket filters are the last filter stage before air reaches your gas turbine compressor. They catch the smallest dust particles left in the air, the ones that slip past coarse and coalescer filters. This guide explains what HEPA, HVX, and HVL class filters mean, how they work, and how to pick the right one for your turbine. Get your 24hr quote today and protect your compressor from fine particle damage.

Gas Turbine Compressor Fouling: How Air Filtration Reduces Power Loss

Compressor fouling is one of the biggest silent drains on gas turbine performance. It builds up slowly, so most sites only notice it once power output has already dropped and fuel bills have already climbed. This guide explains what causes fouling inside the compressor, how much it actually costs a plant in lost power and heat rate, and why staged air filtration, not compressor washing, is the real fix. It also looks at where fouling risk is highest across power generation, oil & gas, marine, and other air-sensitive facilities, and what to check when choosing filtration built to stop it.

Altair Gas Turbine Filters: Is There a Better Alternative?

Altair filters from Parker Hannifin are a trusted name in gas turbine inlet filtration, but the OEM part number often carries a price premium that has little to do with filtration performance. This guide looks at what actually goes into an Altair System 2, Neptune, Vega or Aquila filter, what to check before switching to an OEM-equivalent alternative, and how a proper part cross reference protects your turbine while cutting cost and lead time.

How Often Should HVAC Filters Be Replaced?

Are frequent maintenance issues or declining air quality causing disruptions in your workplace? Replacing HVAC filters on time is essential for improving performance, reducing costs, and maintaining a healthier, more efficient environment. Most HVAC filters replacement can be done generally every 1 to 3 months, depending on usage and environmental factors. What Does an Air […]
