Altec AIR RAD-0040A-1 — 40 CFM Refrigerated Air Dryer, 115V

Made in the USA. Reliable moisture removal for small compressed air systems. The Altec AIR RAD-0040A-1 non-cycling refrigerated air dryer helps protect piping, pneumatic tools, and downstream equipment from moisture. Its compact aluminum heat exchanger, automatic condensate drain, and accessible refrigeration gauges support dependable operation and routine service.

Key Features

• Made in the USA — American-made Altec AIR refrigerated air dryer.
• 40 SCFM rated capacity at standard operating conditions.
• 115V single-phase power for compatible shop and industrial electrical systems.
• Compact all-aluminum heat exchanger designed for low pressure drop.
• Programmable automatic electronic drain removes collected condensate.
• Suction and discharge pressure gauges help monitor the refrigeration system.
• Top-mounted connections and an easy-access cabinet simplify installation and service access.
• 232 PSIG maximum pressure and 140°F maximum inlet temperature, with capacity correction required for actual conditions.

Overview & Applications

A practical option for automotive service, woodworking, maintenance, and light manufacturing applications where refrigerated drying meets the process requirements. Match the dryer to your actual airflow and operating conditions rather than compressor horsepower alone.

Need help sizing? At 120°F inlet temperature, 100 PSIG, and 100°F ambient, the published correction factor reduces this model's capacity to approximately 26.4 SCFM. Call Compressed Air Advisors Online at 877.247.2381 for selection assistance.

Technical Specifications

Optional & Recommended Altec AIR Filter Kits

Filter kits are sold separately. All three options below are matched to the RAD-0040A and have 3/4" NPT connections, an 85 SCFM filter rating, gauge differential pressure indicators, and automatic float drains. The dryer has 1" NPT ports, so suitable transition fittings are required for the 3/4" NPT filter connections. Their filter rating does not increase the dryer's rated capacity.

AR10-0040 — Basic Pre-Filter Kit — Shop Kit →
One X1 grade, 1-micron coalescing pre-filter. Does not meet the minimum filtration requirement for extended warranty eligibility.

AR11-0040 — Recommended Filter Kit — Shop Kit →
One X1 grade, 1-micron coalescing pre-filter and one XA grade, 0.01-micron coalescing after-filter. Altec AIR's minimum recommended filter kit for extended warranty eligibility.

AR21-0040 — 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 the AR11 or AR21 kit also requires registration, proper maintenance, and regular element replacement. Manufacturer terms and exclusions apply.

Warranty

Two-year limited manufacturer warranty. First-year coverage includes qualifying parts and labor under Altec AIR's warranty terms. Second-year coverage is parts only and requires valid registration and documented maintenance. Eligible refrigerated dryers installed with the recommended Altec AIR filter kit may receive extended parts coverage through year five when registration, service, and element replacement requirements are met. Terms, exclusions, and manufacturer approval requirements apply.

Frequently Asked Questions

How do I know whether a 40 SCFM dryer is large enough?

Size the dryer for the airflow passing through it and the actual inlet pressure, inlet temperature, and ambient temperature. The 40 SCFM rating applies at 100 PSIG, 100°F inlet temperature, and 100°F ambient temperature. Higher temperatures or lower pressure can reduce capacity.

Can I use this dryer with a piston compressor?

Yes, provided the compressed air is cooled and conditioned to meet the dryer's operating requirements. An aftercooler and upstream moisture separation may be needed. Maximum inlet temperature is 140°F, and capacity must be corrected for the actual inlet temperature.

What electrical supply does the RAD-0040A-1 require?

This model requires 115 VAC, single-phase, 60 Hz power. Confirm circuit requirements using the equipment nameplate and installation manual.

Which filter kit is recommended?

Altec AIR recommends the AR11-0040 kit with a 1-micron coalescing pre-filter and a 0.01-micron coalescing after-filter. The AR21-0040 adds a 5-micron pre-filter for staged filtration. Both have 3/4-inch NPT connections; the dryer has 1-inch NPT ports, so plan suitable transition fittings.

Are filter kits included with the dryer?

No. The AR10-0040, AR11-0040, and AR21-0040 filter kits are sold separately. The links above select the kit size matched to this dryer.

Does the dryer drain condensate automatically?

Yes. The RAD-0040A-1 includes a programmable automatic electronic condensate drain. Collected condensate must be routed and treated appropriately for your installation.

How do I qualify for the extended parts warranty?

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

Can I install this dryer outdoors or use it for below-freezing dew points?

Select a protected installation location that meets the manual's requirements and the 45–120°F ambient range. Refrigerated dryers are not designed to provide below-freezing pressure dew points; applications requiring those conditions need a suitable desiccant dryer.
