With several special features, two stage air compressor manufactured by Frank Technologies Pvt Ltd is the best energy efficient piston air compressors. These two stage air compressor incorporates simple back-pressure relief valve for reducing initial torque on the motor. Crankshaft, connecting rod, cylinder, valve, and piston are specially designed for 2 stage air compressor . Cylinders are made from special cast iron material with deep radial fins on the outer side for quick heat dissipation. Each cylinder is separately cast, precision-bored and honed for smooth running. The main advantage of these two stage air compressor manufacturers is low specific power consumption and long service life.
Overhung crankshaft, with replaceable crankpin bush made from special steel material, is precision-ground and runs with minimum vibration. The crankshaft is balanced and rotates on two ball bearings.
Precisely machined, one piece connecting rod with solid construction does not require adjustment. Integral splash lubrication.
Stainless steel finger valves are heat-treated, quick-acting. Concentric disc valve plates & spring are made from high quality steel material, having large flow area for longer valve-life and better performance, easy for removal & servicing.
Cylinders are made from special cast iron material with deep radial fins on the outer side for quick heat dissipation. Each cylinder is separately cast, precision-bored and honed for smooth running.
Equalized and balanced pistons are made from aluminium / cast iron material. Each piston has compression ring and oil control rings for optimum efficiency.
