Clean Dry Air Generators

Dominick Hunter

A supply of compressed air is an essential utility for any modern laboratory. Compressed air contains water, oil and dirt that can wear pneumatic instruments and affect the performance and life of analytical instruments.

domnick hunter desiccant dryers are ideal for laboratory use, providing a constant flow of clean, dry compressed air.  Using proven pressure swing adsorption (PSA) technology, the units feature automatic regeneration and integral pre and post filtration to ensure total reliability. Seven models are available with flow rates ranging from 70 L/min to 453 L/min.  The Midas air dryer can operate at a working pressure of up to 12 barg.

By providing totally clean, dry air, domnick hunter pure air generators are ideal for point-of-use laboratory applications including Atomic Adsorption, rheometer purge, NMR sample spinning and lasers purging.  In addition a desiccant dryer can be used as pre-treatment for a zero air or nitrogen generator if the compressed air isn’t clean.

All domnick hunter gas generators are designed and manufactured within a rigorous ISO9001 quality system and are certified to CE.
