The Water Resources Act was introduced to place legal restrictions on industrial discharges either to ground, waterway or storm-water drain with good reason.

Just 250ml of oil can cover acres of water surface, preventing oxygenation; reducing the effectiveness of treatment plants and killing wildlife

A modest 18kW compressor might generate close to ten thousand litres of condensate each year, often containing up to 1000ppm of oil and other waste at the point of discharge.

Because over 99.9% of the condensate is water, it makes sense to clean it on site before discharge to the sewer.

This option of discharging to the sewer system (or foul drain) is controlled by local authorities, which do not usually allow discharges containing more than 20ppm of oil to be introduced to the drains. All the expectations are that such limits will reduce in the future; some European countries already insist on a maximum of 10ppm.

SEPURA offers the most economical, simple, reliable and environmentally sound method of complying with the legal requirements – with outlet quality better than 10ppm for up to 4000 hours of filter life in most applications. We also offer special filters for specific ‘problem’ condensates-call for details.


The SEPURA range of condensate cleaners employs a specially designed filter set to avoid using the troublesome weir, which is found in many traditional separators, similarly, it has neither condensate settlement tank nor separate oil container.

In SEPURA, waste oil is trapped only in the filters, so handling is quick and easy. At service time, simply dispose of the old filters and replace them. There is no need to deal separately with the collected oil or untreated condensate from the settlement tank-because there isn’t any!

SEPURA’s design makes it tolerant of any type of condensate drain. In turn, this means quick and easy low-cost installation. However, we do recommend the use of our ‘ECD’ zero-loss drains to maximise energy savings. Simplicity of design offers economies right across the board, from initial purchase to cost of ownership. SEPURA is also more environmentally friendly, using fewer resources and less energy to make than more complex and expensive designs.

Sterling filters are much less energy-hungry to manufacture than carbon, and are made mostly from recycled materials With such a simple, risk-free product, it’s no wonder SEPURA can offer you a no-quibble guarantee and a 10-year warranty.
