Altec AIR HBS-0150-1 — 150 CFM Single Tower Desiccant Air Dryer
Made in the USA. The Altec AIR HBS-0150-1 brings single-tower simplicity, heated blower regeneration, and factory-installed filtration to industrial compressed air drying. Rated for 150 SCFM inlet flow at 100 PSIG, it delivers a complete desiccant drying package for moisture-sensitive tools, equipment, and processes.
What Makes the HBS Series Unique?
- One tower, fewer moving parts: a rugged design with only three moving parts and no moving parts during the drying cycle.
- Heater and blower regeneration: reconditions the desiccant offline for the next drying cycle.
- Filters included: factory-installed pre- and after-filtration form an integrated package.
- Subfreezing dew point capability: published outlet dew points of 0°F to -50°F, subject to sizing and conditions.
- No refrigerant circuit: desiccant adsorption removes water vapor without a refrigeration compressor.
- Made in the USA: American-made Altec AIR industrial drying equipment.
Overview & Applications
A strong fit for shops and production facilities that need low-moisture compressed air and can schedule time for regeneration between drying periods. A single-tower system offers a straightforward alternative where uninterrupted drying through regeneration is not required.
Plan for offline regeneration. This tower cannot dry process air while it is regenerating, cooling, and repressurizing. Allow suitable downtime or provide an alternate dry-air source. The optional bypass provides an untreated-air path; it does not provide continuous dry air.
Key Features
- 150 SCFM rated inlet flow at 100 PSIG.
- 120 VAC / 1 Phase / 60 Hz standard electrical supply.
- 200 PSIG maximum pressure standard.
- Low watt density heater and industrial duty blower.
- Three-way electric ball valves for dryer operation; optional system bypass selected separately.
- Packaged filtration: published oil removal efficiency of 99.9% at 0.3–0.6 microns and particle removal efficiency of 99.9% at 1 micron. These figures do not mean complete oil-vapor removal.

Choose Your Factory Options
3 Way Bypass Installed: choose No or Yes. The bypass lets air flow around the dryer when required for service or isolation. Air routed around the dryer is not dried.
200 PSI standard: this model includes the 200 PSIG rating without a pressure upgrade.

Frequently Asked Questions
What makes the HBS different from other desiccant dryers?
It uses one desiccant tower with a heater and blower for offline regeneration. Factory-installed pre- and after-filters, only three moving parts, and no moving parts during the drying cycle make it a simple packaged option.
Does it supply dried air while regenerating?
No. The single tower regenerates offline and must cool and repressurize before drying resumes. Plan regeneration during downtime or provide another dry-air source. A bypass passes untreated air and does not replace a second drying tower.
How much airflow can the HBS-0150-1 handle?
Rated inlet flow is 150 SCFM at 100 PSIG. Actual selection also depends on inlet temperature, pressure, moisture loading, required dew point, and available time between drying cycles. Contact us to confirm application sizing.
What dew point can it achieve?
The HBS series offers outlet dew points from 0°F to as low as -50°F, depending on operating conditions and application sizing. Do not assume -50°F is guaranteed at every airflow and duty cycle.
Are pre-filters and after-filters included?
Yes. Factory-installed pre- and after-filters are included. Maintain the filter elements and desiccant according to Altec AIR instructions. Separate RAD refrigerated dryer filter kits are not required for the standard HBS package.
What does the 3-way bypass option provide?
Select Yes for a factory-installed 3-way system bypass, or No for the standard package without that optional bypass. It allows air to be routed around the dryer for isolation or service. Bypassed air is untreated.
Which pressure rating should I choose?
This model includes a 200 PSIG maximum operating pressure rating as standard. There is no separate charge for a 200 PSIG upgrade on this size.
What power supply is required, and is it made in the USA?
The HBS-0150-1 requires 120 VAC / 1 Phase / 60 Hz. It is made in the USA. Verify the selected equipment nameplate, circuit requirements, and installation instructions before installation.
