Altec AIR RAD-0500A — 500 CFM Refrigerated Air Dryer, 460V Three Phase

Made in the USA. The Altec AIR RAD-0500A non-cycling refrigerated air dryer provides moisture removal for industrial compressed air systems. Rated for 500 SCFM at standard conditions, it uses a compact aluminum heat exchanger and automatic condensate drainage to help protect air distribution piping, tools, and downstream equipment.

Key Features

• Made in the USA — American-made Altec AIR refrigerated air dryer.
• 500 SCFM rated capacity at standard conditions.
• 460V Three Phase — choose the listed model for your electrical supply.
• Compact all-aluminum heat exchanger designed for low pressure drop.
• Automatic electronic condensate drain.
• Accessible cabinet and refrigeration pressure gauges for monitoring and service.
• 2" NPT air connections.
• Top-mounted inlet and outlet connections for installation access.

Overview & Applications

Suitable for industrial production, maintenance, and plant air systems where refrigerated drying meets the required air-quality specification. Size to actual airflow and operating conditions rather than compressor horsepower alone.

Sizing example: At 120°F inlet temperature, 100 PSIG, and 100°F ambient, corrected capacity is approximately 330 SCFM. Call 877.247.2381 for selection assistance.

Model & Voltage Options

• RAD-0500A-4: 460 VAC, three phase, 60 Hz.

Technical Specifications

Optional & Recommended Altec AIR Filter Kits

Filter kits are sold separately. The matching kits below have 2" NPT connections and a 700 SCFM filter rating, with gauge differential pressure indicators and automatic float drains. The nominal connection sizes match the dryer ports. The filter rating does not increase dryer capacity.

AR10-0500 — Basic Pre-Filter Kit — Shop Kit →
One X1 grade, 1-micron coalescing pre-filter. This basic kit does not meet the minimum filtration requirement for extended warranty eligibility.

AR11-0500 — Recommended Filter Kit — Shop Kit →
One X1 grade, 1-micron coalescing pre-filter and one XA grade, 0.01-micron coalescing after-filter. This is Altec AIR's minimum recommended kit for extended warranty eligibility.

AR21-0500 — Three-Filter Upgrade — Shop Kit →
One X5 grade, 5-micron pre-filter, one X1 grade, 1-micron pre-filter, and one XA grade, 0.01-micron after-filter for staged coalescing filtration.

Extended warranty eligibility with an AR11 or AR21 kit also requires product registration, proper maintenance, and regular element replacement. Manufacturer terms and exclusions apply.

Frequently Asked Questions

How do I size the 500 SCFM dryer for my system?

The 500 SCFM rating applies at 100 PSIG inlet pressure, 100°F inlet temperature, and 100°F ambient temperature. Size for the actual airflow and use the published pressure and temperature correction factors. At 120°F inlet temperature, 100 PSIG, and 100°F ambient, corrected capacity is approximately 330 SCFM.

What electrical supply does this listing support?

RAD-0500A-4: 460 VAC, three phase, 60 Hz. Select the correct configuration for your supply; these are separate voltage models. Confirm circuit requirements using the equipment nameplate and installation manual.

Which filter kit is recommended?

Altec AIR recommends AR11-0500 with a 1-micron coalescing pre-filter and a 0.01-micron coalescing after-filter. AR21-0500 adds a 5-micron pre-filter for staged filtration. Kits are sold separately.

Do the filter connections match the dryer ports?

The dryer has 2" NPT connections. The matched filter kits have 2" NPT connections and a 700 SCFM filter rating. The nominal connection sizes match. The filter rating does not increase dryer capacity.

Are filters and bypass piping included?

The base dryer listing does not include the separately listed filter kits or bypass piping. Select the filter configuration and installation materials needed for your system.

Does the dryer remove condensate automatically?

Yes. The RAD Series includes automatic electronic condensate drainage. Route and treat collected condensate appropriately for the installation.

How do I qualify for the extended parts warranty?

Install the qualifying Altec AIR recommended filter kit, register the dryer, and keep documented service and regular element replacement records. AR10 alone does not meet the minimum filtration requirement. Manufacturer terms and exclusions apply.

Can this dryer provide below-freezing dew points?

Refrigerated drying is intended for applications where its above-freezing pressure dew point meets the process requirements. Applications requiring below-freezing pressure dew points need a suitable desiccant dryer.
