FS-Curtis CA5PLUS-HUP — 5 HP Air Compressor
A shop that's had a job come back because moisture in the air line fouled a paint job, and can't afford a repeat, needs both a low-clearance tank and the factory dryer that keeps that from happening again.
The FS-Curtis CA5PLUS-HUP is a two-stage reciprocating, ultra pack compressor rated for 5 HP with an 80 gallon horizontal ASME tank, built for multi-bay shops and commercial operations that need compressed air on tap all day. The included Ultra Pack — factory-installed automatic tank drain and refrigerated air dryer — cuts down on the maintenance routine so your team spends less time babysitting the compressor and more time on paying work.
Who the CA5PLUS-HUP Is Built For
- ✅ A paint or finishing shop that's already lost a job to a fisheye defect traced back to wet air in the line, and needs the refrigerated dryer built in rather than risking it again
- ✅ A shop with a low ceiling in the compressor room that's outgrown a 5 HP unit's CFM output and needs more air volume without giving up the horizontal tank's low clearance
- ✅ An owner replacing an aging compressor who wants to consolidate two separate upgrades (more CFM, plus factory air-quality accessories) into one purchase instead of buying a base unit and retrofitting later
- ✅ A multi-bay shop running several air tools at once where a shortfall in continuous CFM means someone's tool starts starving for air mid-job
- ✅ A shop standardizing on FS-Curtis's Ultra Pack tier across locations so every unit has the same accessory bundle and the same maintenance routine for techs moving between sites
What the CA5PLUS-HUP Is NOT Built For
- ❌ Budget-conscious buyers who don't need the extra accessories or higher CFM yet — the base CA5Plus-H costs meaningfully less
- ❌ Home garages doing occasional weekend work
- ❌ Shops needing more than roughly 23-24 CFM continuous — look at a duplex configuration instead
What Makes the CA5PLUS-HUP Different
Commercial 2-Stage Pump
The CA5PLUS-HUP uses an E57, Cast-Iron, Two-Stage, 2-Cylinder pump built for daily, all-day duty cycles — not a hobby-grade single-stage unit that struggles under continuous shop use.
CFM & Pressure Output
Delivers 23.2 CFM @ 175 PSI and holds pressure up to 175 PSI, enough headroom to run impact wrenches, tire equipment, and paint tools without the tank running dry.
Ultra Pack Upgrades
Includes factory-installed automatic tank drain and refrigerated air dryer — upgrades that reduce maintenance and extend the life of the tank and pump versus a base-model compressor.
Power Requirements
Single or Three-Phase, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
- Higher CFM (23.2) at 5 HP
- Factory air-quality accessories
- Low-clearance installs
- Budget-first buyers
- Shops needing 25+ CFM
CA5PLUS-HUP vs. Atlas AF9 (7.5 HP, 80 Gal Commercial) — Which Compressor Is Right for Your Shop?
| Decision Point | CA5PLUS-HUP | Atlas AF9 (7.5 HP, 80 Gal Commercial) |
|---|---|---|
| Horsepower / Tank | 5 HP / 80 Gal Horizontal | 7.5 HP / 80 Gal Vertical |
| CFM @ 175 PSI | 23.2 CFM | 20 CFM @ 175 PSI |
| Included accessories | Ultra Pack bundle (auto-drain/dryer per FS-Curtis config) | Standard commercial configuration |
| Best fit | Shops wanting factory accessories at 5 HP with strong CFM output | Shops wanting more raw horsepower without the accessory bundle |
Choose the CA5+ HUP for factory-installed accessories and solid CFM output at a lower horsepower (and typically lower running cost). Choose the Atlas AF9 if you want more raw horsepower headroom and don't need the Ultra Pack accessories. Both stay inside Alamo’s catalog — call (817) 865-3707.
