The kit includes the 20-gallon ASME portable tank, wheels, axle, handle, vibration pads, and belt guard. According to Castair, buying the complete kit saves 15% compared to purchasing these items individually. At $487.03, it is $112 more than the bare 20P150 tank, and that premium covers five additional components that you would need to source separately anyway for a working portable unit.\u003c\/p\u003e\n\n\u003ch2\u003eComplete Kit Contents\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTank:\u003c\/strong\u003e 20-gallon portable ASME air receiver, 150 PSI rated, 14\"x31\", 9\"x22\" top plate, 85 lbs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWheels:\u003c\/strong\u003e Castair portable compressor wheels (appropriate size for 20-gallon portable — 10\"x1.5\"x0.5\" or 10\"x3\"x0.75\")\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle:\u003c\/strong\u003e AB34 (3\/4\" axle bolt for 20-gallon portable configuration)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHandle:\u003c\/strong\u003e Castair 3432013 (20-gallon portable handle)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVibration Pads:\u003c\/strong\u003e VP100 rubber vibration pads (4\"x4\"x1\", qty as required)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBelt Guard:\u003c\/strong\u003e 3426007 (portable electric belt guard for PK50 and PK60 pumps)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 20P150C\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrice:\u003c\/strong\u003e $487.03\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy the Complete Kit Makes Sense\u003c\/h2\u003e\n\u003cp\u003eIf you are building a complete portable compressor system, you need all of these components. Sourcing them individually requires five separate part numbers, five separate order line items, and paying retail pricing on each small hardware piece. Castair designed the kit specifically for complete portable builds and prices it to save 15% over individual component pricing. The math is straightforward: if you need all the components, the kit costs less.\u003c\/p\u003e\n\n\u003ch3\u003eWhat the Kit Does Not Include\u003c\/h3\u003e\n\u003cp\u003eThe 20P150C covers the tank and hardware.

At 150 PSI, it handles tire inflation, air tools, blow guns, spray equipment, and most common shop air applications. It is not sized for continuous high-demand applications — for those, look at the stationary 60, 80, or 120-gallon ASME tanks. The portable wheels and handle make it manageable to move by two people across flat surfaces.\u003c\/p\u003e\n\n\u003ch2\u003eWhy Buy From Air Compressor Factory Direct?\u003c\/h2\u003e\n\u003cp\u003eWe have been specializing in Castair compressor systems and components since 2016.
