DryAir DA-Midi 2

Get Ultra-Dry Air Whenever You Need It.

The DryAir range uses regenerative PSA technology to remove water vapour from compressed air. Wet air is directed into one of the two desiccant chambers, where nearly all of the water vapour is removed. A small portion of the laboratory air dryers outlet gas is redirected back through the off-line desiccant chamber, purging it of the accumulated moisture. The drying cycle alternates between the two chambers continuously. The unit is available in a custom enclosure with filtration and buffer tank or as an OEM module for integration into 3rd party equipment.

An Apex Laboratory Air Dryer is a useful attachment for any laboratory's external source of air, removing moisture and ensuring the delivery of dry air. Moisture content in the air can contaminate lab instrumentation, impacting on results and in some cases damaging the instrument itself. Compact in size, wall-mountable and light, our series of DryAirs requires little space and with few moving parts mean minimal maintenance is required.

How it works...

Air from an external source enters the generator via the inlet filters. Air then enter the first scrubber tower via a solenoid valve. After passing through the dryer tower the now dry air exits the system via an outlet filter and regulator. A portion of the outlet air is diverted into the second scrubber tower to purge it ready for use. At regular intervals the active tower switches allowing each tower to be purged in turn.


The midi Air Dryer is the Midpoint of our range of fryers, offering flow rates of up to 379 litres/min of dry air containing <1ppm CO2 concentrations. Like most of the products we offer there is the ability to have the machine build to suit your needs, the operating pressure of the unit can be set between 3.5 bar (50 psi) and 10 bar (150 psi) and the output dew point can be decreased to -73°C to give you the exacting gas you require.

The midi dryer series takes the apex customisation to another level. In this series, you can get dry air with flow rates between 56 & 473 l/min. Using the lastest in PSA technology allows for output dew points as low as -70°C and <1ppm CO2 concentrations. With easy installation and a simple maintenance program, the Apex Air Dryer is perfect for any laboratory.

Utilising Pressure Swing Adsorption (PSA) technology our Air Dryers provide ideal performance, efficiency and reliability. Ultra dry air is delivered as required. The design of the dryers allows them to be easily wall or stand mounted. Our Air dryers provide flexibility to match your system requirements. Each system can deliver a variety of flow rates and pressures to suit your specifications.
