{"product_id":"castair-10d","title":"Castair 10D","description":"\u003cp\u003eThe Castair 10D is a major component designation in the Castair catalog — the \"D\" suffix in Castair's naming convention typically indicates a duplex configuration, meaning this is a 10 HP duplex compressor system or related major component. Castair builds duplex systems for shops that need redundancy or higher CFM output from paired compressors with automatic alternation.

This has two practical advantages for a working shop:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eRedundancy:\u003c\/strong\u003e If one pump needs service, the other keeps the shop running.

These are sold as pairs for duplex applications. The duplex Right From The Start kits (RFS001D, RFS002D, RFS003D) include oil, vibration pads, ball valves, flex hoses, and filter elements — everything needed for a proper duplex installation.\u003c\/p\u003e\n\n\u003ch3\u003eCastair 10 HP Duplex System Components\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo pumps:\u003c\/strong\u003e Typically paired C2 pumps (7.5-10 HP each) for duplex 10 HP configurations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo motors:\u003c\/strong\u003e Either 10-215-1 (single-phase) or 10-215-3 (three-phase) motors, one per pump\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eShared ASME tank:\u003c\/strong\u003e 120 or 240 gallon horizontal or vertical, depending on system configuration\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAlternating controls:\u003c\/strong\u003e Automatic alternation to equalize run time between the two pumps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor bases:\u003c\/strong\u003e 213DM (mounted pair) for duplex 10 HP motor base requirement\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWho Needs a 10 HP Duplex System\u003c\/h2\u003e\n\u003cp\u003eA 10 HP duplex unit makes sense when you need more than 35-45 CFM continuous output, when your application requires uninterrupted air supply and cannot tolerate a compressor going down, or when your shop runs multiple high-demand tools simultaneously. Body shops running multiple DA sanders, production lines with pneumatic assembly tools, and automotive dealerships with multiple service bays are typical buyers.\u003c\/p\u003e\n\n\u003ch2\u003eSpecifications — Contact for Confirmation\u003c\/h2\u003e\n\u003cp\u003eManufacturer-provided specifications for the specific SKU \"10D\" were not available on the Castair website at time of writing.
