{"product_id":"20-gallon-vertical-air-compressor-workshop-2hp-single-castair","title":"20 Gallon Vertical Air Compressor | 2HP Single Phase | Cast Iron Pump | Belt Driven | Castair","description":"\u003ch2\u003eOverview\u003c\/h2\u003e\n\n\u003cp\u003eThe CASTAIR Garage Series 20-gallon vertical air compressor delivers professional-grade performance to workshops, garages, and job sites without the premium price tag. This 2HP single-phase unit runs on standard 115V power, making it perfect for contractors, automotive professionals, and serious DIYers who need reliable compressed air for pneumatic tools, tire inflation, and general shop work.\u003c\/p\u003e\n\n\u003cp\u003eWhat separates this compressor from typical garage units is its cast iron pump construction and belt-driven design. While many compressors cut costs with aluminum pumps or direct-drive systems, CASTAIR builds this unit with a slow-running, oil-lubricated cast iron pump that operates at lower RPMs for quieter operation and significantly longer service life.\u003c\/p\u003e\n\n\u003cp\u003eThe 20-gallon ASME-compliant tank is manufactured right here in the USA and finished with a durable blue powder coat that resists corrosion and wear. This tank size hits the sweet spot between air storage capacity and portability, giving you enough reserve air for demanding pneumatic tools while staying manageable for one-person transport around your workspace.\u003c\/p\u003e\n\n\u003cp\u003eForge Claw partnered with CASTAIR to bring you this exceptional compressor because it represents real value for working professionals. The build quality exceeds what you'd typically find in this price range, with automotive-grade components and thoughtful engineering throughout every detail.\u003c\/p\u003e\n\n\u003cp\u003eThe compressor delivers 10.4 CFM at 0 PSI and 6.5 CFM at 100 PSI, providing sufficient airflow for impact wrenches, nail guns, spray equipment, and air tools commonly used in automotive repair, woodworking, and light construction. The single-stage v-twin pump design ensures smooth operation with 360-degree cooling around both cylinders.\u003c\/p\u003e\n\n\u003cp\u003eMobility gets handled by large 10-inch tall, 3-inch wide wheels with steel hubs and dual ball bearings. These wheels roll smoothly over shop floors, gravel, and uneven surfaces without the wobbling or binding you'll experience with cheaper wheel assemblies. The vertical tank design keeps the footprint compact while maximizing your air storage capacity.\u003c\/p\u003e\n\n\u003cp\u003eCASTAIR includes several professional touches that distinguish this compressor from typical garage units. The automotive-type air filter with paper element provides clean intake air while contributing to quieter operation. An easy-to-read sight glass lets you check oil level at a glance without guesswork or removing caps.\u003c\/p\u003e\n\n\u003cp\u003eThe electrical system focuses on reliability with a bleeder pressure switch that allows load-less starts, reducing stress on your electrical circuit and extending motor life. The unit requires a 20-amp outlet and should never be operated on extension cords or GFI circuits, which is standard practice for professional air compressors in this power range.\u003c\/p\u003e\n\n\u003cp\u003eFor professionals who demand reliability day after day, this CASTAIR compressor delivers the durability and consistent performance your work requires. The belt-driven pump runs cooler and lasts longer than direct-drive alternatives, while the cast iron construction handles the thermal cycling and demanding duty cycles that come with professional use.\u003c\/p\u003e\n\n\u003cp\u003eWhether you're running a small auto repair shop, doing finish carpentry, or need reliable compressed air for farm and ranch maintenance, this compressor provides the capacity and durability to handle your daily workload. Forge Claw stocks these units for immediate availability, and our technical support team can help you determine if this model matches your specific air requirements.\u003c\/p\u003e\n\n\u003cp\u003eThe unit's design prioritizes both performance and convenience for the working professional. You won't find yourself constantly waiting for the tank to rebuild pressure between tool uses, and the robust construction means you can count on it showing up ready to work every single day.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\n\u003cul\u003e\n\u003cli\u003eTank Capacity: 20 gallons\u003c\/li\u003e\n\u003cli\u003eMotor: 2HP, single phase, 115V\u003c\/li\u003e\n\u003cli\u003eAir Delivery: 10.4 CFM at 0 PSI, 6.5 CFM at 100 PSI\u003c\/li\u003e\n\u003cli\u003ePump Type: Single stage, belt-driven, oil-lubricated cast iron\u003c\/li\u003e\n\u003cli\u003eTank Construction: ASME-compliant, USA-made steel with powder coat finish\u003c\/li\u003e\n\u003cli\u003ePump Design: V-twin configuration with 360-degree cooling\u003c\/li\u003e\n\u003cli\u003eWheels: 10-inch tall, 3-inch wide with steel hubs and dual ball bearings\u003c\/li\u003e\n\u003cli\u003eElectrical Requirements: 20-amp outlet, 115V single phase\u003c\/li\u003e\n\u003cli\u003eAir Filter: Automotive-type with paper element\u003c\/li\u003e\n\u003cli\u003eOil Level Indicator: Sight glass for easy monitoring\u003c\/li\u003e\n\u003cli\u003ePressure Switch: Bleeder type for load-less starts\u003c\/li\u003e\n\u003cli\u003eConfiguration: Vertical portable design\u003c\/li\u003e\n\u003cli\u003eManufacturer: CASTAIR\u003c\/li\u003e\n\u003cli\u003eTank Origin: Made in USA\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eFeatures\u003c\/h2\u003e\n\n\u003cul\u003e\n\u003cli\u003eCast Iron Belt-Driven Pump — operates at low RPMs with oil lubrication for quiet operation and extended service life compared to direct-drive aluminum pumps\u003c\/li\u003e\n\u003cli\u003eAutomotive-Grade Air Filter — paper element filter provides clean intake air and reduces operating noise for a more pleasant work environment\u003c\/li\u003e\n\u003cli\u003eEasy-Read Sight Glass — allows quick visual confirmation of proper oil level without removing caps or guessing at maintenance needs\u003c\/li\u003e\n\u003cli\u003eUSA-Made ASME Tank — 20-gallon steel tank manufactured domestically with blue powder coat finish for corrosion resistance and durability\u003c\/li\u003e\n\u003cli\u003eHeavy-Duty Wheel Assembly — 10-inch tall wheels with steel hubs and dual ball bearings provide smooth mobility over various surfaces without wobbling\u003c\/li\u003e\n\u003cli\u003eV-Twin Pump Design — twin cylinder configuration with 360-degree cooling ensures consistent performance and even heat distribution during operation\u003c\/li\u003e\n\u003cli\u003eAutomotive Main Bearings — ball bearing crankshaft support provides excellent durability and smooth operation under demanding conditions\u003c\/li\u003e\n\u003cli\u003eLoad-Less Start System — bleeder pressure switch reduces electrical load during startup, extending motor life and reducing circuit stress\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eBenefits\u003c\/h2\u003e\n\n\u003cp\u003eThis compressor saves you significant time on pneumatic tool operations compared to smaller tank units that cycle constantly during use.
