Protecting Your Air Compressors Against Winter

When temperatures drop near or below freezing as is the norm during months like January, you need to take the proper steps to ensure that your air compressor is still functioning and protected from damage caused by components freezing and accumulation of moisture. Maziak’s advice on how to ensure that your air compressor is protected against harsh winter conditions will in turn protect you from having to pay expensive air compressor repair bills.


Drain moisture regularly

Condensation can occur in air compression systems in cold temperatures, leading to moisture accumulation over time. You should take time to regularly drain moisture from the air tanks of your compressor to not only prevent this accumulation, but also to stop the freezing of condensate in the lines.

Use heating systems

Trace heating is a method used to provide a controlled amount of heat to pipelines and vessels. This is especially effective if your air compressor has a refrigerated air dryer with pipework that could potentially drop to a lower temperature than the dewpoint, which can result in condensate being present. Effective heating will prevent your air compressor parts from freezing.

Use synthetic lubricant

If your air compressor uses lubricating oil, you should consider using synthetic lubricants during the colder months. Synthetic lubricants have properties that make the oil less prone to thickening in cold conditions, enabling the smooth function of moving parts.

Check air intake openings

In the case of wet or windy weather, make sure to check air intake openings of your compressor to ensure there is appropriate protection from increased rain or snow blowing in from the outside, as this could cause problems such as saturating the air filter, or forming ice on the air intake.

Insulate air lines

It is important to ensure that air lines are properly insulated as frozen air lines can disrupt the flow of compressed air, which can affect the performance of your compressor and potentially damage the system. Foam rubber, foam glass and fiberglass are all effective insulation materials, make sure to choose an insulation material that is appropriate for the temperature range and environmental conditions of your air compressor system.

Protecting your air compressor from damage during the colder months of the year means a reduction in repair expenses and dependable performance from your compressor in the long run.
