Ingersoll-Rand Type 30 single-acting, 3-stage, aircooled, heavy duty high pressure reciprocating air compressor,
vee-belt driven by a TEFC electric motor mounted on a sub-base c/w following:
10 micron industrial intake air filter/silencer with durable carbon steel canister
100% cast iron frame is designed to support the overhung crankshaft. Frame is completely sealed yet allows
for maximum accessibility
Crankshaft has a unique overhung design. Entire shaft is balanced with integral counterweight to insure
smooth operation
Solid one-piece design connecting rods.
100% cast iron cylinders separately cast and individually bolted to the frame in a V-type configuration.
Cylinders are precision-honed for low oil carryover. Radial fins on cylinders help remove heat and ensure 360 o
cooling
1 st and 2 nd stage piston utilizes standard automotive type piston, 3 rd stage utilizes a steeple type piston
1 st and 2 nd stage use 1 compression ring, 1 oil scrapper ring, 2 oil control rings. 3 rd stage uses 5 compression
rings and 1 oil scrapper ring.
Cast iron fan type flywheel forces a cyclone air blast to provide cooling for the deep finned cylinders and finned
copper tube intercooler and finned tube aftercooler. Flywheel is balanced to keep vibration to a minimum
Intercoolers between stages are of finned copper tube construction to provide maximum cooling area. Located
directly in the flywheel air blast to remove heat of compression keeping running temperatures and power needs
to a minimum, ensuring high air delivery for horsepower expended. Intercooler is provided with a safety valve
to prevent over-pressurization
Intercooler pressure gauges indicate when valve maintenance is required in the case of high inter-stage
pressure.
Splash lubrication of running parts is simple and reliable.
Reliable time-proven finger valves are quick acting and made from premium grade stainless steel. Valve
components are easily removable for maintenance
Centrifugal unloader automatically bleeds air from intercooler and cylinders preventing compressor from
starting against full load. This protects the motor from premature wear.
Aircooled aftercooler lowers discharge air temperature to within 40 o F of ambient
High pressure switch for auto stop/start control (supplied loose)
Direct on lin starter
Totally enclosed wire belt guard
