Compressed Air

FRLs (filter, regulator and lubricator units) condition compressed air at the point of use. They remove contaminants, set the correct pressure and add lubrication for pneumatic tools and components.

FRL Options

• Combination FRL units – three functions in one assembly
• Filter/regulators – space-saving two-in-one
• Modular units – build custom air prep assemblies
• Accessories – gauges, brackets, shutoff valves and drains
• Metal and polycarbonate bowls – match pressure and environment

Choosing an FRL

Size the unit for peak air flow and select filter micron and regulator range. Skip the lubricator if components are pre-lubricated or air must be oil-free. Metal bowls are required in some environments.

Centro carries FRL units and parts for compressed air systems.

Compressed air dryers remove water vapor to prevent condensation, corrosion and freezing in air lines. Dry air protects tools, instruments and products, especially in painting, food and outdoor applications.

Dryer Types

• Refrigerated dryers – economical dew points around 35-39°F
• Desiccant air dryers – dew points to -40°F or lower
• Membrane dryers – point-of-use drying without power
• Heatless and heated regeneration – desiccant efficiency options

Choosing a Dryer

Select based on required pressure dew point, flow, inlet temperature and ambient conditions. Pre-filters protect desiccant dryers from oil. Size for summer conditions to avoid wet air.

Centro supplies compressed air dryers and replacement desiccant.

Compressed air drains remove the condensate that collects in filters, dryers, receivers and drip legs. Removing water automatically protects equipment and keeps air quality up.

Drain Types

• Timer drains – simple, programmable discharge
• Zero air-loss drains – discharge water only, saving energy
• Float drains – mechanical, no power needed
• Internal filter bowl drains – automatic draining at filters

Choosing a Drain

Consider the condensate volume, pressure, power availability and oil content. Zero-loss drains pay back quickly by stopping wasted air. Route condensate to an oil-water separator before disposal.

Centro carries compressed air drains for filters, receivers and dryers.

Compressed air filter elements are the replaceable parts that do the filtering inside compressed air housings. Regular replacement keeps air quality high and pressure drop low.

Element Types

• Particulate elements – remove solids
• Coalescing elements – remove oil and water aerosols
• Activated carbon elements – remove oil vapor
• OEM interchangeable elements – fit major brands

Replacement Tips

Replace elements annually or when pressure drop rises. Have the housing brand and model ready to find the right element.
