Constructional Features


100 % Oil Free Air:
Oil content in air leads to Contamination of the compressed air system or the final Product. Compressed air from Colt Reciprocating Compressors is free from oil particles thereby Increasing the life of Line Equipments , Efficient and wear resistant packing rings isolate oil to the first compartment of the distancepiece.
No Foundation Required:
Pre - tested Colt Compressors are free from high vibration levels and hence can be placed on skids. Colt Compressors are equipped with Anti Vibration Mounts which make them the first choice for raised floor installations.
Complete Packaged Solution:
Trouble free installation with Plug & Play type compressors. These are self contained packages with compressors, radiators, motor, air receiver, dryer and a programmable PLC control system.
Pre - tested for Performance:
Each assembly of every Colt Compressor undergoes careful testing in a state of the art testing Facility. Completely assembled packages are then tested on test beds at variable load settings.
