Castair 80 Gallon Vertical Air Receiver Tank — 200 PSI ASME Coded (Part# 80V200)
The Castair 80V200 is an 80-gallon vertical air receiver tank rated for 200 PSI working pressure and built to ASME code. It is the right tank for shops building a serious stationary compressor where floor space matters. Vertical orientation puts 80 gallons of air storage into a 24-inch diameter footprint — it fits in a corner, against a wall, or on a compressor skid without occupying the linear floor space a horizontal tank requires.
This is an ASME-coded vessel, which means it meets the standard for pressurized vessels in commercial and industrial applications. That is what you need for a stationary shop compressor used in a professional environment. It pairs correctly with 5-7.5 HP cast iron two-stage pumps and motors in the Castair lineup — enough buffer capacity to prevent short-cycling while keeping the installation compact.

Why the Vertical Tank Has a Smaller Floor Footprint
Compare the 80V200 to its horizontal counterpart, the 80H200: the horizontal tank is 20 in dia x 66 in long, while this vertical tank is 24 in dia x 48 in tall. The vertical tank is slightly wider in diameter but takes up far less floor space because all that length goes up instead of out. If your compressor is going in a corner or against a shop wall with limited floor depth, the vertical tank is often the practical choice.
The 13 x 32 in top plate on this tank is sized for mounting a pump-motor assembly directly on top — a common configuration for cast iron compressor builds where the pump mounts on the tank and is belt-driven from the motor. That keeps the entire assembly compact and makes the compressor portable with a pallet jack or forklift without needing a separate skid.
ASME Code Compliance
An ASME-coded tank has been designed, fabricated, and tested to the American Society of Mechanical Engineers pressure vessel standard. It carries a stamped certification. This is what commercial and industrial air systems require — it is what your insurer expects and what a safety inspector will look for. If you are building a compressor for professional shop use, do not use a non-coded tank. The Castair 80V200 meets the standard.
Matching This Tank to Your Compressor
The practical sizing guideline for compressor tanks is 4-6 gallons of storage per CFM of pump output. An 80-gallon tank is correctly sized for a cast iron two-stage pump delivering roughly 13-20 CFM at 175-200 PSI working pressure. That covers the range of most 5-7.5 HP applications. The goal is enough tank volume that the pump runs for several minutes per cycle rather than short-cycling every 30-60 seconds. Short-cycling wears out motors and pumps far faster than steady run cycles.
If you are running a 10 HP compressor with higher CFM output, step up to the 120-gallon vertical tank (part# 120V200) for better buffer capacity. If you are running a smaller 3-5 HP compressor for light shop use, the 60-gallon vertical (60V150, 150 PSI) may be sufficient.
Installation Notes
- Weight: 230 lbs empty — use a pallet jack or forklift for positioning, do not try to hand-carry this
- Drain: Install a manual or automatic drain valve at the tank bottom — condensate collects at the lowest point and must be drained regularly to prevent corrosion from the inside out
- Safety valve: Install an ASME-rated pressure relief valve appropriate for your compressor output — this is not optional
- Stability: Vertical tanks must be secured to prevent tipping — anchor to the floor or wall, especially if foot traffic or equipment movement is nearby
- Pump mounting: The 13 x 32 in top plate accommodates pump-on-tank mounting configurations — verify your pump base dimensions before ordering
Vertical vs. Horizontal — Choosing Between the 80V200 and 80H200
Both tanks are 80 gallons, 200 PSI ASME coded, and 230 lbs. The difference is entirely in how they fit your installation:
- 80V200 (vertical): 24 in dia x 48 in tall — corner or wall installation, pump-on-top mounting, smaller floor footprint
- 80H200 (horizontal): 20 in dia x 66 in long — bench or skid mount, trailer mounting, lower center of gravity for mobile applications
If the compressor is staying in one spot on a shop floor and you want to minimize the floor area it occupies, the vertical tank is almost always the right choice. If it is going on a trailer, under a bench, or needs to lie flat for stability reasons, choose the horizontal.
Castair ASME Tank Range
- 60 Gal Vertical (60V150): 150 PSI, 138 lbs — entry-level coded tank for smaller compressors
- 80 Gal Vertical (80V200): 200 PSI, 230 lbs — this tank
- 80 Gal Horizontal (80H200): 200 PSI, 230 lbs — horizontal version for skid or bench mounting
- 120 Gal Vertical (120V200): 200 PSI, 355 lbs — step up for 10 HP and higher
- 120 Gal Horizontal (120H200): 200 PSI, 355 lbs — horizontal for larger installations
- 240 Gal Horizontal (240H200): 200 PSI, 700 lbs — high-capacity industrial storage
