How to Size an Industrial Air Compressor Correctly
Start with measured air demand and required pressure, then build in realistic allowances for leakage, simultaneity and growth.
Read guide →Practical guidance for selecting, installing and operating an industrial compressed-air system in South Africa.
These guides explain the decisions behind a reliable industrial compressed-air system. Use them with the calculators, then let our team verify the final selection against the application and site conditions.

Choose the compressor technology around operating pattern and lifecycle cost, not only the purchase price.

VSD is valuable when demand changes; fixed-speed can remain efficient where the base load is stable and well matched.

Set pressure from the process requirement at the point of use, then solve excessive pressure loss instead of overpressurising the whole plant.

A receiver is working storage: its useful capacity depends on volume, pressure band and the demand it must support.

Air treatment should be specified from the required air quality at the point of use, not added as a generic accessory.

Workshops should size around the busiest realistic combination of tools—not the largest single tool or the sum of every tool.

Replacing like-for-like can repeat old inefficiencies. Measure how the whole system behaves before selecting new capacity.

Mining selection must include ambient conditions, filtration, cooling, service access, redundancy and logistics—not only FAD.

The cheapest quotation can be the most expensive system if it wastes power, lacks support or fails to meet the process requirement.
Read guide →Send your demand, pressure, operating hours, electrical supply and site location. We will recommend a compressor, receiver and air-treatment package.
