Types of compressor purges

When the air is compressed, condensate (water, dust, oil, etc.) is generated, which is deposited firstly in the accumulator tank(s) and secondly in the pneumatic network, which can end up damaging elements and structures through corrosion. There are several ways of draining these accumulated condensates, either manually (manual drains) or with automatic drains (electronic timed, capacitive or float drains).

In the pneumatic installation, the drains are installed in the cyclone separators, in the air tanks and in the line filters. The dryers also have their own drains, the condensate from which must be treated.

Types of compressor purges

Depending on their purging technology, there are different types:

  • Manual purges: The user purges manually as often as he/she deems appropriate.
  • Automatic Drains: Automatic drains discharge condensate autonomously either by periodicity, by filling or by detection of accumulated condensate.
    • Capacitive drain: This automatic drain system is the most efficient, as it will not cause any type of air loss. By means of a level sensor, it will ensure an evacuation adjusted to the condensate level.
    • Timed Electronic Vent: This electronic vent allows you to set both the frequency with which the purge is carried out and the time it will be open, for example (opens every hour for 10 seconds). Requires electrical connection.
    • Purga de boya: Utiliza un flotador que actúa dependiendo de la acumulación de agua y condensados.

We remind you that the venting system is essential to maintain the good condition of the installation and the air quality, avoiding the effects of corrosion and condensation downstream.
