This is the vertical-tank counterpart to the horizontal 460V model — same horsepower and CFM output, same 460V power configuration, but in a vertical tank layout that takes up less floor space at the cost of more ceiling clearance. If your compressor room has the height to accommodate a vertical tank, this is typically the tighter-footprint option.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e Manufacturer specification sheets for this specific model were not available at time of listing beyond what appears in the product name.

Piston compressors are typically rated at 60–75% duty cycle, meaning they need cooling time between run cycles. If your shop is running air tools all day or multiple shifts, the rotary screw design is the appropriate choice.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cdiv class=\"faq-item\"\u003e\n\u003ch3\u003eWhat CFM output does the R30312VG30-460 produce, and what air tools or equipment will it support?\u003c\/h3\u003e\n\u003cp\u003eAt 100 PSI this unit delivers approximately 113–125 CFM depending on exact configuration — enough to simultaneously run multiple spray guns, impact wrenches, DA sanders, and continuous-flow equipment like plasma cutters or air-driven conveyor systems. For reference, a 1\" impact wrench draws roughly 10–15 CFM and a production spray gun 10–25 CFM, so this machine has capacity for a full production floor.

At 30 HP the running amp draw is approximately 40–44 amps; you'll want a dedicated 60-amp 3-phase circuit with appropriate wire gauge per NEC guidelines for motor loads.

The all cast iron construction Cast Air has used since 1991 out of Spicer, MN contributes to consistent heat dissipation, which is a key factor in fluid longevity.

The R30312VG30-460's 120-gallon vertical tank and enclosed pump assembly contribute to lower noise output. For installations near occupied office space or customer-facing areas, the rotary screw design is a practical advantage, though hearing protection is still appropriate in the immediate compressor room.\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cscript type=\"application\/ld+json\"\u003e\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@type\": \"FAQPage\",\n  \"mainEntity\": [\n    {\n      \"@type\": \"Question\",\n      \"name\": \"What is the duty cycle on the R30312VG30-460, and how does it compare to a reciprocating piston compressor?\",\n      \"acceptedAnswer\": {\n        \"@type\": \"Answer\",\n        \"text\": \"The R30312VG30-460 is a rotary screw compressor rated for 100% continuous duty — it can run 24\/7 without a mandated rest period.
