Cast Air Industrial Series Heavy Duty Shop Air Compressor — Model I518VC1-S
The Cast Air I518VC1-S is a 5 HP, 80-gallon vertical industrial air compressor at ,213. It's the vertical tank version of Cast Air's entry-level Industrial Series 5 HP unit — delivering the same cast iron pump quality in a configuration that uses less floor space than a horizontal 80-gallon tank.
At ,213, the I518VC1-S is priced higher than the horizontal equivalent (I518HC1-S at ,356) — a 57 premium for the vertical orientation. That premium reflects the different mounting hardware, pump orientation, and manufacturing complexity of vertical cast iron configurations. Whether it's worth it depends entirely on whether floor space is a real constraint in your shop.
Who This Compressor Is For
- Single-technician shops with limited floor space where a horizontal 80-gallon tank is too long to fit comfortably
- Light automotive and service shops that want to tuck the compressor into a corner or against a wall efficiently
- Shops where ceiling height is adequate but floor space is genuinely limited
- Small operations upgrading to industrial cast iron quality in the most space-efficient package available
Key Features
- 5 HP Single-Phase Motor: Low electrical demand — approximately 22–28A at 230V; works on most standard shop electrical services
- 80-Gallon Vertical Tank: Full 80-gallon storage in a compact floor footprint — significantly less floor area than horizontal tanks of equivalent capacity
- Cast Iron Pump (VC): Vertical-configuration cast iron pump — same durable cast iron material and construction quality as horizontal models, adapted for vertical mounting
- Single-Stage Compression: Practical working pressure for the full range of standard shop pneumatic tools
- Industrial Series Construction: Commercial-grade quality throughout
- Stationary Configuration: Permanent installation design
I518HC1-S vs. I518VC1-S — Which Should You Buy?
- I518HC1-S (,356) — horizontal: Lower cost, longer footprint, lower profile, easier condensate drainage by gravity. The right choice if floor space isn't the limiting factor.
- I518VC1-S (,213) — vertical (this unit): 57 more, significantly smaller floor footprint, taller. The right choice when floor space is genuinely constrained and ceiling height is adequate.
If you have the floor space, buy the horizontal — it costs less and drains more easily. If you don't, the vertical is the answer.
Understanding the I518VC1-S Model Number
- I — Industrial Series
- 5 — 5 HP motor
- 1 — Series designator
- 8 — 80-gallon tank
- VC — Vertical Cast iron pump
- 1 — Single-stage compression
- -S — Stationary
Installation Requirements
- Electrical: Single-phase 230V — 5 HP typically draws 22–28A; 30A dedicated circuit usually sufficient
- Floor: Level concrete — vertical tanks need stable, level surface for safety and longevity
- Ceiling: Confirm adequate height including service access clearance above the unit
- Anchoring: Consider floor anchoring in higher-vibration environments
- Condensate: Regular drain maintenance — plan for accessible drain valve access
