It shares the same 10x24\" cylinder and 150 PSI rating as the direct drive model, but the top plate is a 6x16\" format — the wider footprint that belt drive compressor assemblies require. If you are building or rebuilding a belt drive portable compressor, this is the correct tank.\u003c\/p\u003e\n\n\u003cp\u003eAt $145.22, the 8P150B costs a bit more than the direct drive 8P150D ($106.26), and the weight difference reflects the larger top plate and additional hardware: 35 lbs versus 30 lbs. Both are the right tank for their respective drive type — the distinction is purely about which motor-pump arrangement you are running.\u003c\/p\u003e\n\n\u003ch3\u003eTank Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 8P150B\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e 8 gallons\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 10\" diameter x 24\" length\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop Plate:\u003c\/strong\u003e 6\" x 16\" — sized for belt drive (BD) motor-pump mounting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure:\u003c\/strong\u003e 150 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 35 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrice:\u003c\/strong\u003e $145.22\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Portable (horizontal orientation, designed for wheeled cart or frame)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASME Code:\u003c\/strong\u003e Non-code (appropriate for portable compressor units at this pressure and volume)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Belt Drive Needs a Bigger Top Plate\u003c\/h3\u003e\n\u003cp\u003eOn a belt drive compressor, the motor does not mount directly over the pump. Instead, the motor sits offset from the pump, connected by a V-belt that drives a pulley on the crank. This arrangement puts the motor and the pump side by side on the top plate rather than stacked. The 6x16\" top plate on the 8P150B gives you the length to bolt down both the motor and the pump head at the correct center-to-center distance for the belt alignment.\u003c\/p\u003e\n\n\u003cp\u003eOn a direct drive unit, the motor bolts straight onto the pump crank — the whole assembly is compact and the 6x7\" top plate on the 8P150D is sufficient. Order the wrong tank and the mounting holes will not match. Confirm your drive type before you order.\u003c\/p\u003e\n\n\u003ch3\u003eBelt Drive Advantages at This Tank Size\u003c\/h3\u003e\n\u003cp\u003eBelt drive compressors run the pump at a lower RPM than direct drive units, typically using a smaller motor pulley driving a larger pump pulley. The slower pump RPM means:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eLower operating temperature — easier on rings, valves, and oil\u003c\/li\u003e\n\u003cli\u003eLonger pump service life between rebuilds\u003c\/li\u003e\n\u003cli\u003eGenerally quieter operation than direct drive at equivalent output\u003c\/li\u003e\n\u003cli\u003eMore serviceability — the belt is a maintenance item you can replace without pulling the pump\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe tradeoff is that belt drive compressors are physically larger and slightly heavier for the same air output. For a shop owner who wants a portable unit that holds up over years of daily use, belt drive is often the better long-term investment even in the 8-gallon class.\u003c\/p\u003e\n\n\u003ch3\u003e8 Gallons of Capacity in Practice\u003c\/h3\u003e\n\u003cp\u003eEight gallons handles intermittent pneumatic tool use well — framing nailers, finish nailers, brad guns, blow guns, and tire inflation. For sustained-draw tools like impact wrenches, die grinders, or sand blasters, the compressor will cycle frequently at this tank size. That is appropriate for the portable class.\u003c\/p\u003e\n\n\u003cp\u003eIf you need more capacity without going stationary, Cast Air's 20-gallon portable (20P150C complete kit) is the next step up. For most portable applications, the 8-gallon belt drive is a proven, reliable size.\u003c\/p\u003e\n\n\u003ch3\u003eTank Only vs. Complete Kit\u003c\/h3\u003e\n\u003cp\u003eThe 8P150B is the tank-only purchase.

For portable compressor tanks at 150 PSI in the 8-gallon size class, ASME code certification is not required by most regulatory agencies. Cast Air builds these tanks to the quality standard appropriate for their rated service pressure. If your installation requires ASME-coded tanks — a permanent shop air system in a jurisdiction that mandates it, for example — Cast Air manufactures coded vessels in larger sizes. For portable compressor use, non-code is standard and correct.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Buy From Air Compressor Factory Direct?\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpecialist supplier:\u003c\/strong\u003e We carry Cast Air OEM tanks sourced directly from the manufacturer in Minnesota.
