This is the base tank for contractor-style portable units — the kind that rides on a job site, fits in a truck bed, and gets used hard. Cast Air manufactures this tank in Minnesota using proper steel construction with pressure-rated fittings, and it is sized and drilled specifically for direct drive motor-pump mounting.\u003c\/p\u003e\n\n\u003cp\u003eIf you are building a direct drive portable compressor from the pump up, or replacing a failed tank on an existing unit, the 8P150D is the starting point. The top plate dimensions are drilled for DD mounting — not belt drive. Get this right before you order.\u003c\/p\u003e\n\n\u003ch3\u003eTank Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 8P150D\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 7\" — sized for direct drive (DD) 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 30 lbs\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\u003eDirect Drive vs. Belt Drive — Why the Top Plate Matters\u003c\/h3\u003e\n\u003cp\u003eThe top plate is the drilled mounting surface on top of the tank where the motor-pump assembly bolts down. The 8P150D has a 6x7\" top plate — compact because on a direct drive unit, the motor couples directly to the pump crank. There is no belt, no pulley, and no extended motor offset. The footprint is smaller and the whole assembly sits tighter.\u003c\/p\u003e\n\n\u003cp\u003eThe belt drive version (8P150B) uses a 6x16\" top plate to accommodate the longer motor-and-pulley arrangement. If you order the wrong tank, the mounting holes will not line up. Confirm your drive type before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eWhat the 8 Gallon Capacity Means in Practice\u003c\/h3\u003e\n\u003cp\u003eEight gallons is the standard entry point for contractor portables. It gives you enough buffer for intermittent tool use — framing nailers, finish nailers, brad guns, blow guns — without the compressor running continuously. For high-demand tools like impact wrenches or die grinders that pull sustained CFM, an 8-gallon tank will cycle the compressor frequently. That is the nature of the size class, not a defect.\u003c\/p\u003e\n\n\u003cp\u003eIf your application demands more air storage, Cast Air also offers a 20-gallon portable tank (available as the complete kit 20P150C). For most finish and framing work, the 8-gallon is the right balance of portability and capacity.\u003c\/p\u003e\n\n\u003ch3\u003eBuild Options: Tank-Only vs. Complete Kit\u003c\/h3\u003e\n\u003cp\u003eThe 8P150D is the tank-only option. If you need a complete portable unit with wheels, axle, handle, and vibration pads already included, Cast Air offers the \u003cstrong\u003e8P150DC complete kit\u003c\/strong\u003e. The kit approach saves approximately 15% versus sourcing those components separately, and everything is matched to fit.\u003c\/p\u003e\n\n\u003cp\u003eOrder the 8P150D (tank only) if:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYou already have wheels, axle hardware, and a handle from a previous build\u003c\/li\u003e\n\u003cli\u003eYou are replacing just the tank on an existing compressor\u003c\/li\u003e\n\u003cli\u003eYou have a custom mounting or cart arrangement in mind\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eOrder the 8P150DC (complete kit with casters) if:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eYou are building a new portable compressor unit from scratch\u003c\/li\u003e\n\u003cli\u003eYou want one part number that covers the full portable assembly\u003c\/li\u003e\n\u003cli\u003eYou want the 15% kit savings on the wheels, axle, and handle\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eNon-Code Rating Explained\u003c\/h3\u003e\n\u003cp\u003eThe 8P150D is rated non-code. For portable compressor tanks at this pressure (150 PSI) and volume (8 gallons), ASME code certification is not required by most regulatory frameworks. These are the same tanks used in standard contractor and light shop compressors. Cast Air manufactures them to quality standards appropriate for their rated service pressure — the non-code designation reflects the regulatory classification, not a shortcut in materials or construction.\u003c\/p\u003e\n\n\u003cp\u003eIf your application requires ASME-coded tanks — for instance, a permanent shop installation in a jurisdiction that mandates it — Cast Air makes coded tanks in larger sizes. For portable compressor use, the 8P150D is the correct choice.\u003c\/p\u003e\n\n\u003ch3\u003eTank Accessories Available Separately\u003c\/h3\u003e\n\u003cp\u003eIf you need wheels, axle hardware, or a handle to complete your build, Cast Air offers these individually:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eW7.5x1.5x.5:\u003c\/strong\u003e 7.5\" x 1.5\" x 1\/2\" bore wheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eW10x1.5x.5:\u003c\/strong\u003e 10\" x 1.5\" x 1\/2\" bore wheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eW10x3x.75:\u003c\/strong\u003e 10\" x 3\" x 3\/4\" bore wheel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAB12:\u003c\/strong\u003e Axle bolt 1\/2\" for 8-gallon portable\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eOr skip the individual parts and order the 8P150DC complete kit.\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 stock Cast Air OEM tanks and parts direct from the Minnesota manufacturer.
