How A Membrane Dryer Works

How A Membrane Dryer Works

The need for filtering compressed air to make it usable is vast. Compressed air is not usable as a utility directly from the compressor source. It needs to be prepared and cleaned by a compressed air filter or dryer to various levels of cleanliness, depending on the task at hand. Spray painting, blasting, pneumatic tool preservation, surface preparation, pneumatic controller protection, and worker safety are just a few of the needs for clean, compressed air.

In today’s workplace, compressed air is the other utility that must be prepared to a level of cleanliness necessary for the task at hand. It seems to be the utility that is most often used and normally given the least attention or thought.

The membrane dryer is a unique and efficient way to remove various contaminants from an existing compressed air system, and lowers both the dew point and the relative humidity all at the same time.

The membrane dryer is a unique and efficient way to remove various contaminants from an existing compressed air system, and lowers both the dew point and the relative humidity all at the same time.

The membrane dryer is a progressive system of filtration media, designed to work with your existing compressed air system. The membrane dryer consists of a unique four stage filtration system. This system progressively cleans the compressed air from liquids and other contaminates. With an automatic moisture discharger located under the second stage filter, any liquids removed will be expelled once an ounce of liquid is collected.

After the four stage pre-filter has properly cleaned the compressed air, the membrane goes to work.

The membrane, though a process of osmosis, removes any remaining moisture vapor back into the ambient atmosphere. The result is ultra clean and ultra dry air, with a dew point reduction of -40 degrees, and a relative humidity resulting in the single digits.

Walmec North America uses a proprietary four stage pre-filter system to properly clean and dry the compressed air. Then the membrane dryer further improves the air quality by lowering both the dew point and relative humidity.

Membrane Dryers Provide Unmatched Performance for Years!

The membrane dryer does not use any electricity and only requires simple maintenance of the four stage prefilters. With regular maintenance, the membrane dryer will provide years, and years of superb and unmatched performance for the low initial investment and the affordable consumables.

When properly installed with a ball valve prior to the membrane dryer, the use of compressed air, is reduced to a flow only when the ball value is in the on position and the membrane itself allows a small sweep air to exhaust the removed moisture.

Its compact design allows for simple installation and will fit in the tightest of spaces, and can go around or into a corner situation if necessary.

As technology continues to evolve the use of a membrane dryer is expected to replace the refrigerated air dryers as a way to provide the ultra clean, and ultra dry air when and where it is truly needed at a lower cost to provide and maintain.
