Condensate disposal — a legal & environmental obligation

Discharging oil-contaminated condensate to a drain, watercourse or ground is illegal and carries serious consequences. Every compressed air system needs a properly installed and maintained separator.

Regulatory Alert

Discharging any condensate to a storm drain, stream, or groundwater is NOT permitted. Non-compliance with environmental legislation carries serious legal and financial consequences.

The scale of the problem

A single 25 hp compressor running 8,000+ hours per year generates around 1,000 litres of condensate containing significant quantities of oil, enough to contaminate many acres of water surface.
