{"product_id":"castair-31hp-3-phase-rotary-screw-air-compressor-horizontal-r313hp50","title":"Castair 31HP 3-Phase Rotary Screw Air Compressor  Horizontal - R313HP50","description":"\u003cp\u003eThe Castair R313HP50 is a 31HP 3-phase horizontal rotary screw air compressor. This is a purpose-built industrial compressor for shops and facilities that need substantial continuous air output — the 31HP rating puts it just above the 30HP tier, which in practice delivers similar output to the 30HP class with performance tuned to a specific motor and drive configuration. The horizontal tank orientation keeps the installation profile low, which is useful in facilities where vertical clearance is limited.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Manufacturer specification sheets for this model were not available at time of listing.
