This is the standard large-capacity horizontal storage tank in the Castair lineup, designed for stationary compressor installations where floor space allows horizontal placement. At 24 inches in diameter by 68 inches long, it lies flat on channel supports — the right choice when you have the horizontal floor space but limited ceiling height, or when you are plumbing multiple compressor units into a shared central supply. Weight is 355 lbs empty.\u003c\/p\u003e\n\n\u003ch2\u003eTank Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e 120 gallons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOrientation:\u003c\/strong\u003e Horizontal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank Dimensions:\u003c\/strong\u003e 24\" diameter x 68\" length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop Plate Size:\u003c\/strong\u003e 17\" x 44\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure:\u003c\/strong\u003e 200 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 355 lbs (empty)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Power coded, ASME certified\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 120H200\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eASME Certification and Code Requirements\u003c\/h2\u003e\n\u003cp\u003eAll Castair tanks are ASME certified and power coded. This is not optional for commercial and industrial installations — it is required by most local codes, insurance underwriters, and OSHA for pressure vessels above certain sizes in workplace environments. The ASME stamp means the tank was manufactured to specific material, welding, and inspection standards, and carries a calculated safe working pressure. A non-coded tank may be cheaper; it is also a liability and code violation in most jurisdictions.\u003c\/p\u003e\n\n\u003ch3\u003ePowder Coated Exterior\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePowder coat finish for corrosion resistance in shop environments\u003c\/li\u003e\n\u003cli\u003eChannel-style base supports for horizontal mounting (no legs)\u003c\/li\u003e\n\u003cli\u003eStandard connection points for inlet, safety valve, drain, and gauge\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eHorizontal vs. Vertical: Which Do You Need?\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e120H200 (Horizontal, $1,755.83):\u003c\/strong\u003e 24\"W x 68\"L footprint — requires floor space but lower ceiling clearance.

The 200 PSI rating gives you headroom above the typical 175 PSI cutout on industrial two-stage compressors. Go horizontal when you have ceiling constraints (shop with low mezzanine, for example) or when you are running two compressors and want to manifold them into a single tank — the channel base makes it easy to position the tank against a wall and run piping overhead. If you have the ceiling height, the vertical 120V200 saves floor space.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy From Air Compressor Factory Direct?\u003c\/h2\u003e\n\u003cp\u003eWe have been specializing in industrial air compressor components since 2016.
