The Castair 8TT150NC Complete Portable Kit is the 8TT150N twin tank air receiver packaged with everything you need to build a mobile compressor: wheels, axle, handle, vibration pads, and belt guard included. At $329.41, it saves approximately 15% compared to buying the tank and accessories separately. If you are building or rebuilding a portable compressor and do not already have the mobility hardware, the NC kit is the straightforward choice.
The tank itself is the same 8TT150N receiver: 8-gallon total capacity across two tanks, 17x34" footprint, 9x24" top plate for pump/motor mounting, 150 PSI maximum working pressure, 68 lbs empty. Non-code (non-ASME) receiver, which is the correct designation for portable and contractor-class equipment. Castair builds these in Minnesota with cast iron — heavier and more durable than the sheet-steel tanks common on consumer and light-duty compressors.
What the "NC" kit adds beyond the tank: wheels and axle for rolling mobility, a handle for control and maneuvering, vibration pads to isolate pump vibration from the tank and frame, and a belt guard for safety and compliance when running a belt-driven pump. These are not afterthoughts — a portable compressor without vibration isolation will develop loose fittings and stress cracks faster, and a belt-driven pump without a guard is a maintenance and liability issue. The kit includes them at a price below what you would pay sourcing them one at a time.
Key Features
- Complete kit configuration: Tank plus wheels, axle, handle, vibration pads, and belt guard — everything to build a mobile compressor platform except the pump and motor
- 15% savings vs. individual components: At $329.41, the kit price is approximately 15% below buying the 8TT150N tank and mobility accessories separately
- 8-gallon twin tank receiver: 8-gallon total capacity, 17x34" footprint, 9x24" top plate — same confirmed specs as the standalone 8TT150N
- 150 PSI working pressure: Rated for the full range of standard shop air tools — impacts, ratchets, tire inflation, blow guns, and moderate-duty continuous use
- Wheels and axle: Genuine rolling mobility — move the compressor around the shop or on a job site without lifting it
- Handle: Control and balance point for moving the unit — proper handles matter when you are moving a loaded compressor across uneven surfaces
- Vibration pads: Isolate pump vibration from the tank and frame — extends service life of fittings, gauges, and the tank itself; reduces noise in operation
- Belt guard: Safety and compliance for belt-driven pump configurations — required in most commercial environments, included here rather than sourced separately
- Cast iron construction: Castair uses cast iron throughout — longer service life than sheet-steel consumer units, holds up to the vibration and thermal cycling of daily commercial use
- Non-code (non-ASME) receiver: Correct designation for portable and contractor-class compressors — if you need ASME certification, that is a different product category
- Minnesota manufactured: Domestic production, custom builds available, direct manufacturer support through us

Available Configurations
- 8TT150NC (this unit) — Complete kit: 8TT150N tank plus wheels, axle, handle, vibration pads, belt guard. $329.41. Best value if you need the full mobility package.
- 8TT150N — Tank receiver only: Same tank, no kit accessories. Order this if you already have wheels, handle, and pads from a previous compressor or are building into a fixed frame. Contact us for pricing.
- 8TT150G — Gas designation tank: Same core tank, gas-engine build designation, tank only. Contact us for pricing.
When Does a Shop Need This vs. Stepping Up or Down
- Buy the 8TT150NC if: You are building a new portable compressor from the tank up and do not have wheels, handle, and vibration hardware on hand. The 15% kit savings versus piece-sourcing is real, and having the matched components from the same manufacturer simplifies the build.
- Choose the 8TT150N instead if: You already have mobility hardware from a previous compressor that fits this tank footprint — no point paying for parts you do not need.
- Step up if: You need an ASME-coded receiver for a regulated or fixed-installation environment, or you need more than 8 gallons of capacity for high-demand sustained tool use (sandblasting, production air tools, paint booths).
- Step down if: Your use is genuinely occasional or light-duty — there are smaller, lighter portable receivers that will serve intermittent shop use at lower cost.
- Gas vs. electric pump: The tank is the same regardless of your drive choice. The 8TT150NC kit accepts either a gas engine or electric motor pump assembly. Tell us your intended drive and we can confirm compatibility.

Frequently Asked Questions
- Does the kit include a pump or motor? No. The 8TT150NC provides the tank and mobility hardware. Pump and motor/engine are sourced separately based on your drive configuration (electric or gas).
- What pump and motor are compatible? Call us at 866-217-0063 and tell us your intended CFM and pressure requirements. We can match you with the right Castair or compatible pump package for this tank.
- Is this ASME coded? No. The 8TT150NC is a non-code (non-ASME) receiver, which is standard for portable compressor applications. If your jurisdiction or application requires ASME certification, contact us before ordering.
- Can this be used with a gas engine? Yes. The tank accepts either a gas-engine or electric-motor pump assembly. The 8TT150G is the gas-specific designation for the same tank if that matters for your application.
