Filters remove dirt, water, and other contaminants that, left unchecked, can hasten the demise of air-powered equipment. Many of the latest versions have high dirt-holding capacity for longer life, improved flow paths that lead to better energy efficiency, and can even alert users when they need maintenance. Here’s a look at some of the newest products on the market.
Repairable inline filterRIF-Series inline filters are designed to protect small air tools such as grinders, impact wrenches, and screwdrivers. The light and compact anodized-aluminum units can install directly before an air tool, extending life and reducing downtime by capturing foreign particles in the air stream. RIF filters can also be used in low-pressure hydraulic applications. Connection sizes range from 0.12 to 0.5-in. NPT with elements rated for 20-, 40-, or 90-µm filtration.

Lightweight polymer design
Series AS air-preparation units have a lightweight polymer construction and smooth surface, important in industries like food and packaging. The series includes filter choices of 40, 25, 5, 0.3, or 0.01 µm, and activated carbon, as well as regulators, lubricators, and other modular components that permit standard and custom combinations. Ports have inch or ISO-G (BSPP) metal threads in sizes from 0.25 to 1 in. Systems can be customized with lockout or soft-start valves, distribution blocks, filter-regulator combinations, and other accessories.

Clean-air package
The Stainless Steel Air Prep Series includes filters with all metal components, including internals, made of 316 SS. All particulate filters use dense-pack elements to ensure maximum impaction, minimal pressure drop, and long duty life. Each component in the Series adheres to the NACE MR0175 Standard. The stainless units resist chemical degradation and are suited for food/beverage, pharmaceutical, natural gas, offshore, and wastewater-treatment applications.
