Ingersoll-Rand “Type-30”, single acting, 2-stage, aircooled, heavy duty reciprocating air compressor, v-belt driven by
a TEFC electric motor mounted on a ASME coded horizontal air receiver tank, c/w :
Dry type 10-micron industrial intake air filter/silencer with durable canister
100% cast iron frame. Cylinders are bolted directly to the frame.
Unique overhung crankshaft design. Entire shaft is balanced by integral counterweight to insure smooth
operation.
Solid one-piece design connecting rods are simple and easy to maintain.
Cylinders are 100% cast iron, separately cast and individually bolted to frame in V-type configuration.
Cylinders are precision-honed for low oil carryover. Radial fins on cylinders help remove heat and ensure 360 o
cooling.
Precision balanced low pressure aluminium and high pressure cast iron pistons.
Cast iron fan type flywheel forces an air flow to provide cooling for the deep finned cylinders and multi-finned
copper tube intercooler. Flywheel is balanced to keep vibration minimum.
Intercooler between stages is of finned copper tube construction to remove heat of compression. This keeps
running temperature and power needs minimum.
Interstage pressure safety valve at intercooler to prevent over-pressurization.
Splash lubrication of running parts is simple and reliable.
Low Oil level switch prevents unit from operating when oil level is low.
Centrifugal unloader automatically bleeds air from intercoolers and cylinders to prevent compressor from
starting against load. This protects the motor from premature wear.
Auxiliary valve for constant speed control.
Direct on line starter mounted and wired.
