Filters, Regulators Lubricator

Water Traps:

Water is not compressible and when water gets into pneumatic valves and cylinders, it cannot give way and damage the pneumatic equipment. An ordinary water trap can only catch the droplets of water when the air and droplets pass through the filter.

Any water condensing after the filter passes the filter as compressed air and not as water. The filter also cannot create air, if it only gets a stream of water entering the filter. This stream of water will run straight through the filter.

Regulators:

Frequently Asked Questions

Why is a water trap essential for pneumatic systems?

Compressed air naturally holds moisture which, when compressed, turns into liquid water. Since water is non-compressible, it can cause "water hammer" effects, rust internal components, and wash away essential lubrication. A water trap (filter) removes this moisture before it reaches your expensive tools.

What is the difference between a standard 25-micron filter and a coalescing filter?

A standard 25-micron filter removes larger solid particles like rust and scale. A coalescing filter is far more precise, designed to merge tiny oil and water aerosols into larger droplets that can be drained. Airpower offers coalescing filters that achieve a 0.01 mg/m³ oil carry-over for high-purity applications.

Do you supply replacement elements for other filter brands?

Yes. We supply a comprehensive range of replacement filter elements compatible with most major brands (often referred to as "opposition filters"). This allows you to maintain high air quality without being locked into a single manufacturer's pricing.

When should I use a precision regulator instead of a standard in-line regulator?

Standard regulators are fine for general air tools, but precision regulators are necessary for applications requiring highly stable pressure with minimal "droop," such as laboratory testing, tensioning, or delicate pneumatic instrumentation.

Can an activated carbon filter remove oil vapor from compressed air?

Yes. While coalescing filters remove liquid oil, activated carbon filters are required to remove oil vapor and odors. This is essential for Class 1 air quality, often required in food, beverage, and pharmaceutical packaging.
