Compressor system with membrane dryer – dry compressed air 24/7

Our compressor systems with membrane dryers reliably deliver dry compressed air – continuously, even during 24/7 operation. As membrane drying operates without regeneration cycles, the required air quality is continuously available for your application at all times.

The integrated membrane technology enables a dew point reduction of up to 35 K, thus ensuring consistently high air quality. The compressor systems with dryers are designed for ambient temperatures of +5 to +40 °C and are suitable for use in numerous industrial applications with high demands on compressed air quality.

Consistent air quality without interruptions to the regeneration process
Protection of sensitive equipment and extended service life
Hygienic conditions and reproducible results
Low purge air requirements ensure high energy efficiency
Minimal maintenance: just one filter change per year
Smooth start-up thanks to an integrated pressure relief valve

FAQ – Frequently Asked Questions about the compressor system

A compact system that generates oil-free compressed air and removes moisture using a membrane dryer – for absolutely dry, clean air.

For businesses with low to medium air requirements that need the highest air quality and a compact design.

35–860 l/min at 5 bar – ideal for many industrial applications.

Minimal – no oil changes, automatic condensate evaporator, annual filter change.

Yes – Dürr Technik develops bespoke compressor systems to meet specific requirements.

The membrane dryer lowers the pressure dew point relative to the ambient temperature. With a reduction of up to 65 K, compressed air can be dried to well below room temperature. Example: At an ambient temperature of +30 °C, the system achieves a pressure dew point of –35 °C. This ensures that reliably dry air is available at all times for a wide variety of applications.

Tank capacity: U = 3 litres, W = 10 litres, T = 25 litres, H = 55 litres, P = 90 litres
