GHH RAND is one of the world’s leading air-technology companies.
Since over 50 years GHH RAND develops, designs, and manufactures
oil-injected and oil-free compressed air solutions for many
different industries and applications. We offer a wide range of
solutions and services for air and gas compression: from airends
to customized compressed air systems, always with highest reliability
in the industry. Our work is driven by passion to high technology
and high performance.
For production of our screw airends we utilize newest and advanced
technologies, which allow us to reach minimum manufacturing
tolerances, high precision assembly and testing under extreme
conditions. The quality of our airends is very well known and
acknowledged world wide.
Our engineers continuously develop our products in order to fulfill
and even exceed customer’s requirements. Highest efficiency
and reliability in the market are results of improvement of airend
design and production processes done over the years.
Our delivery program includes belt driven, direct driven and gear
driven airends. The airends built with high precision are suited
for work under the most difficult conditions 24 hours per day.
Many features and highlights of the airends allow OEM-customers
easy selling of their products to end users.
Recently we added to our famous series CE & CF the newest
development OS series. With the new OS series we reached even
higher level of efficiency of screw compressors. Simplicity of
the design increases its reliability.

You can choose from a wide selection of components, all of which
have been specifically designed for our airends in order to optimize
efficiency and reliability when operating in your compressor package.
These components are proven designs and can be supplied
in airend kits to help reduce your costs and your logistics. Inlet
valves, minimum pressure valves, thermostats and combination
blocks are all available for you to select with our airends.
Lubricant
Your compressor system will last longer and be more reliable when
using our high quality mineral and synthetic coolants Primecool
and Primecool Plus. These lubricants have been engineered with
excellent start up and operating lubrication characteristics. Not
only will this provide long life, excellent cooling performance
and improved compressor efficiency but you will also benefit from
