Hook & Claw: Pressure & Vacuum
Mr Northey invented the Hook & Claw principle in the 1930's. Like all good inventions the concept is quite simple. Two contra rotating rotors compress the gas and the hooks allow inlet and discharge through ports. There is no contact between the rotating parts and no need for lubrication. There is no sealing liquid either, so the air or gas handled is left clean and uncontaminated. There is no wear and no consumption of oil or other liquid.
The Northey hook and claw machine can be used in vacuum or compression. They are true positive displacement machines which means the flow is proportional to the speed and relatively high compression ratios can be used.
For a more indpeth explaination of how our machines work why not read the Working Principle or to learn more about the Northey Advantage
The Northey Advantage
The following briefly demonstrated the whole life cost savings of a Northey Oil-free machine in the utilities market, using information gathered by one of our customers who wished to reduce their man hours involvement with regards to servicing and regular maintenance.
The Working Principle
Northey compressors and vacuum pumps are purely rotary machines, yet they possess the positive action of the piston type due to the unique principles of design and operation, and must not be confused with either reciprocating or other rotary machines.
