Compressing air causes moisture in the air to condense. If this moisture is not removed from the compressed air flow, it can corrode piping, clog pneumatic tools and contaminate production. The Atlas Copco SD membrane air dryer with pre-filters removes moisture, oil and particles, resulting in clean, dry compressed air. Let’s look at its simple design and important advantages.
Incoming air flows through a bundle of hollow permeable fibers. Water molecules move through the permeable wall of the fiber and dried air follows its path to the outlet of the dryer. At the outlet, a small amount of dry air is used to purge (dry out) the dryer’s outer shell where moisture is being gathered. The wet flow is expelled from the dryer through vent holes.
Saturated air in dryer shell evacuates to atmosphere. A valve determines amount of purge and thus the dew point performance.
The unique design of an SD membrane air dryer offers special advantages.
