Donaldson Ultrair M and Ultrair S filter
elements are designed for high quality filtration of
compressed air and gas in industrial applications.
Ultrair M/S element performance has been validated in
accordance with ISO 12500, which assures that your
application will receive compressed air quality as
specified by ISO 8573-1.
The combination of flow channel design optimized
through the use of computational fluid dynamics
software, careful selection of filtration media, and
advanced production technology give the Ultrair V
element a very low pressure drop while maintaining a
high separation efficiency.
Ultrair M/S elements utilize a three-dimensional
polyester microfiber fleece media, which is ideal for
coalescing and draining away oil and water aerosols
in the airstream. In addition, this media will capture
and retain particulate contaminants through direct
impaction, sieving and diffusion.
Applications
The Donaldson Ultrair M and Ultrair S coalescing filter
elements are ideal in the following industries
and applications:
• Plant air
• Pharmaceutical
• General machine fabrication
• Air conditioning technology
• Process Industry
(instrumentation and control air)

Sizing example for pressure which
deviates from nominal pressure:
Vnom = 200 cfm, operating pressure = 130 psi
Vcorr = Vnom/fp
Vcorr = 200 cfm/1.25 = 165 cfm
