Altec AIR HRL-0040-1 — 40 SCFM Heatless Desiccant Air Dryer
Made in the USA. The Altec AIR HRL-0040-1 is a twin-tower heatless regenerative desiccant air dryer for industrial compressed air systems requiring a -40°F/-40°C pressure dew point. Factory-installed pre-filters and after-filters, regulated purge flow, and a Pro-Logic controller provide a complete drying package for moisture-sensitive equipment and processes.
40 SCFM is the rated inlet flow. At standard rating conditions, approximate regeneration purge is 6 SCFM, leaving approximately 34 SCFM of usable outlet flow. Match the dryer to downstream demand and operating conditions, including the compressed air needed for regeneration.

- Factory-installed pre-filters and after-filters with differential-pressure gauges and pre-filter timer drain.
- ASME / CRN approved pressure vessels and ASME safety relief valves.
- E-Z switching valves designed for long valve life.
- ETL-listed Pro-Logic controller with NEMA 4 enclosure, standby mode, and manual cycle stepping.
- Regulated purge flow, tower pressure gauges, desiccant fill/drain ports, and control-line filter/regulator.
- 1/2" NPT inlet and outlet connections; standard 120V single-phase power.
Applications & Sizing
A practical choice for manufacturing, instrumentation, pneumatic controls, and industrial processes that need very dry compressed air. The twin-tower design regenerates one desiccant bed while the other dries the air stream. Select equipment for the required dew point and actual airflow rather than compressor horsepower alone.
Provide cooled inlet air and effective upstream bulk-water removal. Maintain the supplied filters and drain, and leave sufficient access for valve, filter, and desiccant service. For operating pressures other than 100 PSIG, use the applicable capacity correction and purge setting; do not exceed the selected unit's maximum pressure rating.

Configure Your Dryer
| Base Unit | No 3-way bypass; no outdoor low-ambient kit; 150 PSIG maximum pressure. |
|---|---|
| 3-Way Bypass — Optional | Factory-installed bypass package; select Yes to add. SKU option code: 3. |
| Outdoor Low Ambient — Optional | Factory-installed outdoor low-ambient package for operation down to -20°F ambient; select Yes to add. SKU option code: L. |
| Pressure Rating | Select 150 PSIG standard or the optional factory 200 PSIG configuration. The 200-PSIG option adds the SKU suffix -200. |
Build the combination you need: all three selections can be combined. Choose the 3-way bypass for service flexibility, the outdoor low-ambient kit for cold installations, and the 200-PSIG rating when system pressure requires it. Bypass mode routes air around the drying process and does not maintain the dryer's outlet dew point.

Frequently Asked Questions
Is the 40 SCFM rating inlet flow or delivered outlet flow?
It is inlet flow at 100 PSIG inlet pressure, 100°F inlet temperature, and a -40°F pressure dew point. Approximate purge consumption is 6 SCFM, leaving approximately 34 SCFM for downstream use at those conditions. Account for regeneration air when checking compressor capacity.
Are pre-filters and after-filters included?
Yes. Factory-installed pre-filtration and after-filtration are included, along with filter differential-pressure gauges and a timer drain on the pre-filter. Maintain filters and drains to help protect the desiccant and downstream equipment.
What does the 3-way bypass option do?
The factory-installed 3-way bypass lets airflow be routed around the dryer for service or isolation. Air flowing through the bypass is not being dried by the dryer; assess downstream moisture requirements before using bypass mode.
Do I need the outdoor low-ambient kit?
Select this option for applications requiring the factory outdoor low-ambient package, rated down to -20°F ambient. The standard base unit does not include this package. Confirm site conditions and installation requirements before ordering.
Can the base unit operate at 200 PSIG?
No. The standard unit is rated to 150 PSIG maximum. Select the 200 PSIG pressure-rating option for a factory-configured 200-PSIG unit. This option changes the maximum pressure rating; the advertised airflow remains the 100-PSIG inlet rating.
Can I combine all three options?
Yes. Choose the bypass, outdoor low-ambient package, and pressure rating independently. Each combination has its own SKU and price. The base unit is No bypass, No outdoor low-ambient kit, and 150 PSIG standard pressure rating.
What power supply and dew point does this dryer use?
Standard power is 120 VAC, single-phase, 60 Hz. The standard outlet pressure dew point is -40°F/-40°C, corresponding to ISO 8573-1 Class 2 for water. Confirm circuit requirements against the selected equipment's nameplate and installation instructions.
How should I size the dryer for my system?
Use actual inlet pressure, inlet temperature, required pressure dew point, and downstream airflow demand. Apply the appropriate capacity corrections and allow for purge consumption. The 120°F maximum inlet temperature is an operating limit, not the full-capacity rating condition. Call 877.247.2381 for selection assistance.
