Oil Free Dry air ensuring the highest quality air at the point of use for critical applications.

Parker Zander Oil Free Air System.

Innovative engineering and technology.


Combining sophisticated OIL-X fi ltration technology with an optimised drying system, the OFAS is designed to deliver consistent high performance over an extended period. Air quality is third party validated to ISO 7183 and ISO 8573-1 and also offers class 0 for total oil. So you can be completely confident of your compressed air quality.

ISO 8573-1 CLASS 0 AIR

The OFAS is third party validated by Lloyds register to provide ISO 8573-1 Class 0, with respect to total oil from both oil lubricated and oil free compressors, ensuring the highest air at the point of use for critical applications.

Energy Saving Technology

Standard on all units, it automatically

adapts dryer operation to the ambient inlet

conditions and compressed air demand,

ensuring optimum energy consumption and

full utilisation of the desiccant material.

HMI display screen

Large screen display offering a wealth of

clear, useable, real-time information.

High strength desiccant

Cartridges are snowstorm filled with high

strength desiccant that has a 5-year lifetime,

providing consistent drying, re-generation

and dewpoint.

Pre-mounted filters

New series OIL-X filters engineered to

provide validated ISO 8573-1 performance.

Threaded top end-cap

Threaded end-cap enables the

straightforward replacement of the

desiccant cartridge.

Purge setting

The purge air can be set at minimum

operating pressure easily, without the

need for specialist tools.

Corrosion protected column

With a 10-year guarantee, to ensure

a long operational life.

Full bore internal flow paths

Featuring optimised flow management

for reduced pressure drop.

Full bore cylinder valve system

Low pressure loss valves provide full air

flow and minimal back pressure, whilst

robust cylinders extend service intervals.

Base plate

Designed for pallet trucks, allowing

for easy, time-saving installations
