Castair 8 Gallon Portable Air Receiver Tank Kit — 150 PSI with Casters (Part# 8P150BC)
The Castair 8P150BC is a complete portable compressor tank kit built around the 8-gallon belt-drive portable tank. It ships as a ready-to-assemble package: the 8P150B base tank plus wheels, axle, handle, vibration pads, and belt guard — everything you need to turn a bare tank into a functional portable compressor unit. Buying the complete kit saves 15 percent compared to purchasing the components separately.
This is a non-code tank, which is appropriate for portable and light-duty applications. If you are building a small portable compressor for a service vehicle, a contractor setup, or light shop use — not a fixed commercial installation — the 8P150BC is the correct product. It handles 150 PSI working pressure and gives you the mobility of a wheeled compressor without the cost of a large stationary unit.

BD vs. DD Portable Tank — What the Difference Means
Castair offers two 8-gallon portable tanks in 150 PSI non-code configuration:
- 8P150B (BD): Belt-drive portable, 10x24 in, top plate 6x16 in, 35 lbs — this tank, in the 8P150BC kit
- 8P150D (DD): Direct-drive portable, 10x24 in, top plate 6x7 in, 30 lbs — in the 8P150DC kit
The key difference is the top plate size. The BD (belt-drive) tank has a 6x16 in top plate to accommodate the footprint of a belt-drive pump and motor assembly — a wider, longer mounting surface. The DD (direct-drive) tank has a smaller 6x7 in top plate sized for a direct-drive pump that mounts directly to the motor. If you are building a belt-drive compressor, you need the BD tank. If you are using a direct-drive pump-motor unit, use the DD configuration (8P150DC). Ordering the wrong top plate means your pump will not mount properly.
What You Get in the Complete Kit
The 8P150BC kit converts the bare tank into a mobile compressor unit:
- Wheels/casters: Allow the unit to be rolled to where it is needed
- Axle: Mounts the wheels to the tank frame
- Handle: Tilt-and-roll handle for easy maneuvering
- Vibration pads: Isolate pump vibration from the tank and floor, reduces noise and extends component life
- Belt guard: Safety guard for the belt and pulley — required for safe operation of any belt-drive compressor
Everything in this kit is designed to work together as a Castair system. You still need to source the pump, motor, regulator, safety valve, and electrical components separately — this kit is the tank and the mobility hardware, not a complete ready-to-run compressor.

Non-Code Tank — What That Means for Your Application
This is a non-ASME-coded tank. That is appropriate for portable applications where the tank is not permanently installed as part of a commercial or industrial fixed system. Portable contractor compressors and service vehicle compressors typically use non-code tanks. If your application requires a permanently installed commercial compressor — a shop compressor bolted to the floor, used daily in a commercial environment — you need an ASME-coded tank. Castair's ASME-coded tanks start at the 60-gallon vertical (60V150) and go up from there.
Right-Sizing the Tank for Your Application
At 8 gallons and 150 PSI, this tank is sized for small portable compressors driving 1-2 air tools intermittently. It is not designed for continuous production use or for driving high-demand tools like sanders, grinders, or impact wrenches for extended periods. For that kind of use, you need a larger stationary tank — 60-80 gallons minimum — and a higher-output pump. The 8-gallon portable is for service work, inflation, light nailing, and similar intermittent applications where you value mobility over sustained output.
