It shares the dual-tank architecture of the 8TT150N (non-code twin tank), but the \"E\" suffix designates an electric-specific configuration — typically a top plate sized and drilled for electric motor mounting requirements rather than the standard non-code variant.\u003c\/p\u003e\n\n\u003cp\u003eIf you are building or rebuilding a twin tank portable compressor with an electric motor, the 8TT150E is the correct tank. If you need the standard twin tank, see the 8TT150N. If you are unsure which variant your existing compressor uses, the top plate dimensions are the distinguishing spec — call us before ordering.\u003c\/p\u003e\n\n\u003ch3\u003eWhat the Twin Tank Design Provides\u003c\/h3\u003e\n\u003cp\u003eThe twin tank configuration places two smaller cylindrical receivers side by side, connected at the manifold, rather than using a single longer or taller vessel. The 8TT150E delivers the same total air storage as a single 8-gallon tank but with a geometry that keeps the height lower and distributes weight across two support points. For portable compressor use, that means a more stable unit on uneven surfaces and a lower center of gravity.\u003c\/p\u003e\n\n\u003cp\u003eThe 17x34\" overall footprint (based on the 8TT150N base specs) gives you roughly the equivalent air storage of an 8-gallon single tank, but spread across a wider, lower profile. This is why twin tank designs are common in contractor portables — they roll and park more stably than a vertical tank, and the lower profile fits in more vehicle cargo configurations.\u003c\/p\u003e\n\n\u003ch3\u003eTank Specifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e 8TT150E\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConfiguration:\u003c\/strong\u003e Twin tank (dual horizontal receivers, side by side)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCapacity:\u003c\/strong\u003e 8 gallons total\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Dimensions:\u003c\/strong\u003e Approximately 17\" x 34\" (based on 8TT series; confirm current spec with us if critical)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTop Plate:\u003c\/strong\u003e 9\" x 24\" (8TT series standard — verify E variant plate dimensions before ordering for an existing motor)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure:\u003c\/strong\u003e 150 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e Approximately 68 lbs (8TT series base weight; E variant may differ slightly)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDrive Configuration:\u003c\/strong\u003e Electric motor mounting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eASME Code:\u003c\/strong\u003e Non-code\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eElectric Configuration vs. Non-Code Variant (8TT150N)\u003c\/h3\u003e\n\u003cp\u003eCast Air offers the twin tank in both the 8TT150N (standard non-code) and 8TT150E (electric) variants. The distinction between them lies in the top plate configuration. Electric motor mounts may require different bolt patterns, different plate lengths, or specific clearances for conduit and terminal box access that differ from a gas-engine or belt-drive layout.\u003c\/p\u003e\n\n\u003cp\u003eIf you are replacing a tank on an existing electric-motor twin tank compressor, match the existing top plate dimensions to the 8TT150E spec before ordering. If you are building from scratch with an electric motor, the 8TT150E provides the correct mounting geometry for that application.\u003c\/p\u003e\n\n\u003cp\u003eFor the full twin tank assembly with wheels, axle, handle, vibration pads, and belt guard included, Cast Air also offers the 8TT150NC complete kit (based on the 8TT150N).
