The Northey Advantage

Here at Northey Tech we are passionate about reducing environmental impact while enhancing reliability, helping you keep costs down.

Products such as our High-Speed Turbo Blowers and side channel blowers can cut carbon emissions by up to 35%, and our compressors and vacuum pumps significantly reduce running costs due to the low maintenance and part replacement requirements.

Our blower, compressors and vacuum pumps are all dry and oil-free - which is particularly vital within clean manufacturing environments such as food packaging and processing, beverage, pharmaceuticals, laboratories and medical as there is no risk of oil contamination.

We understand every business is unique – which is why our team of specialists can work with you to create bespoke products suitable for your needs.

All our products offer a low energy, low maintenance solution with an outstandingly low total cost of ownership or total expenditure (TOTEX) over their lifetime.

Here are just some of the key advantages to choosing Northey, based on our customers’ feedback:

  • Save up to 35% in energy costs and carbon consumption
  • Ultra-low maintenance requirements – every two years on average
  • No lubricating fluid - saving thousands of pounds on oil consumption
  • No lubricating or sealing fluid required- removing risk of contamination to product or environment
  • Long mean time between failures (MTBF)
  • Customisable for your application
  • Adaptable for challenging environments including potentially explosive atmospheres (ATEX), toxic or cryogenic applications
  • Options on corrosion-resistant components and coatings

Continually Innovating for Complex Problems

We take our name from founder and inventor Mr A. J. Northey, who invented the Hook & Claw device as a rotary engine in the 1920s, adapting it as a dry vacuum pump and compressor in the 1930s.

From the original applications of the Hook & Claw as a supercharger [an air compressor that increases the density of air supplied to an engine] for cars and on vacuum pumps for railway braking systems, we have continually developed and extended our product range.
