FS-Curtis CA5PLUS-H — 5 HP Air Compressor
Low overhead clearance and a tighter budget don't have to mean settling for a weaker compressor — the CA5+ horizontal pairs a low-profile tank with the same efficient two-stage pump as the rest of the CA5+ line.
The FS-Curtis CA5PLUS-H is a two-stage reciprocating compressor rated for 5 HP with an 80 gallon horizontal ASME tank, built for shops and commercial operations that need compressed air on tap all day without paying for accessories they don’t need.
Who the CA5PLUS-H Is Built For
- ✅ A shop working out of a building with a low drop ceiling in the compressor room where a tall vertical tank won't clear the joists, but this horizontal unit's lower profile fits without any structural changes
- ✅ An owner replacing a worn single-stage compressor that's started tripping breakers under daily load and wants two-stage reliability without paying for the standard CA5-H's extra 90 lbs of iron
- ✅ A general repair shop running impact wrenches, tire equipment, and air tools off one line during a busy Saturday rush that needs commercial-duty reliability, not a hobby-grade unit that chokes under continuous draw
- ✅ A shop tucking the compressor under a mezzanine or raised storage platform where the low horizontal tank fits under the structure without cutting a notch
- ✅ A buyer comparing the CA5+ H against the standard CA5-H and choosing the lighter, more compact unit specifically because the shop's floor or dock has a weight limit on that section
What the CA5PLUS-H Is NOT Built For
- ❌ Home garages doing occasional weekend work — a smaller portable unit costs far less
- ❌ Shops needing more than roughly 18-19 CFM continuous — look at the CA7.5 or a duplex unit instead
- ❌ Buyers wanting factory auto-drain/dryer accessories standard — the Ultra Pack (CA5Plus-HUP) adds those, this base unit doesn't
What Makes the CA5PLUS-H Different
Commercial 2-Stage Pump
The CA5PLUS-H 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 18.5 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.
Power Requirements
Single or Three-Phase, 230V/460V options available. Confirm your panel and breaker sizing with an electrician before delivery.
- Low-clearance installs
- Lighter 510 lb footprint
- General repair shops
- Home garages / occasional use
- Shops needing 25+ CFM
CA5PLUS-H vs. Atlas AF5 (5 HP, 60 Gal Vertical) — Which Compressor Is Right for Your Shop?
| Decision Point | CA5PLUS-H | Atlas AF5 (5 HP, 60 Gal Vertical) |
|---|---|---|
| Horsepower / Tank | 5 HP / 80 Gal Horizontal | 5 HP / 60 Gal Vertical |
| Airflow | 18.5 CFM @ 175 PSI | 18.0 CFM @ 90 PSI (AF5 rated to 125 PSI max, no 175 PSI rating published) |
| Tank orientation | Horizontal — fits under low overhead clearance | Vertical — narrower floor footprint |
| Best fit | Shops with low ceiling clearance needing a larger 80-gallon reserve | Shops with tight floor space, standard ceiling height |
Choose the CA5+ H when overhead clearance is limited and you need an 80-gallon reserve. Choose the Atlas AF5 when floor space (not ceiling height) is the deciding constraint. Both stay inside Alamo’s catalog — call (844) 480-6059.
