About Cast Air Major Components
- Category: Major Components — this class of Cast Air products covers assemblies and components that are more complex than individual valves; typically includes unloader assemblies, valve assemblies, control blocks, and similar higher-level compressor control hardware
- Manufacturer: Cast Air (Castair) — US-based compressor component manufacturer with a long track record in industrial and commercial compressor hardware
- Common Applications: Industrial reciprocating compressors, commercial air systems, stationary and portable compressor platforms depending on the specific component

What to Have Ready When You Call
- Compressor make and model — helps us confirm the B70 is the correct replacement part for your specific unit
- Original part number from the compressor — if the B70 is listed in a parts manual or on the original component, have that reference available
- Port sizes and configuration — inlet and outlet NPT sizes, pilot port location if applicable
- Operating pressure — your system working pressure and cutout pressure help confirm the correct pressure range specification
- Application type — electric or gas engine drive, single-stage or two-stage, continuous or intermittent duty
Why Manufacturer Spec Availability Varies
- Cast Air produces a large range of compressor components, and not all part numbers are listed with full public specifications on their website
- Some major components are application-specific or built to OEM specifications for compressor manufacturers who integrate them into their equipment
- The B70 designation may correspond to a specific configuration within a broader component family — verifying this before ordering prevents sourcing errors
- We work directly with Cast Air and can confirm current availability, specifications, and lead times for parts not fully documented online
