Our UMD series uses hollow fiber technology to reliably reduce the dewpoint (PDP) of compressed air. The PDP is achieved by forcing water vapor through the semi permeable hollow membrane wall. This action reduces the PDP of the remaining air within the hollow fiber tube. The water vapor is subsequently purged out of the housing by sweeping dry air over the outer diameter of the fiber wall. This allows membrane dryers to operate continuously 24 hours a day 7 days a week for a decade or more. We recommend changing the coalescing pre-filter every six months to maintain proper efficiency. No other service/maintenance is required. In order to provide the most cost-effective solution for your application we offer four (PDP) Pressure Dew Point levels to meet your specific application requirements.

The table below is color coded to simplify your UMD choice. The outlet PDP is dependent on the inlet PDP as well as flow rate, and pressure. The flow rate chart is based on a 100 psig inlet. Please use the correction factor multiplier below for other pressures.
- Determine what your outlet PDP requirement is (keep in mind your inlet PDP temperature 40ºF or 100ºF
- Determine what your outlet (scfm) flow needs to be
- After choosing PDP outlet and outlet scfm – pick the model on the left
Example: (1) -20°F PDP @ (2) 10 scfm = (3) Model UMD450V

Multiply the correction factor by the outlet PDP flow to provide an estimated flow at the given PSIG. Pressures below 100 psig will have lower scfm output, and higher output above 100 psig.
