ABAC DRY 690 Compressed Air Refrigerated Dryer (406 CFM, 14 Bar, Three Phase) and 2 x filters

Best-in-class filtration performance: ABAC’s new filter series features next generation engineering to safeguard your air-powered equipment with maximum efficiency, reliability and ease of use.

1 year standard warranty. If you purchase the dryer with the two filters, this extends the warranty on the dryer to 2 years.

The industry standard CFM rating is taken at 3 degrees C. Please ensure you check other sellers are using this figure and not the higher CFM rating taken at 5 degrees C.

ABAC provides refrigeration dryers to remove condensate and vapor so that dry, compressed air is produced in a continuous, cost-efficient way. Today’s compressed air generation process is not only a matter of producing air: purity and cleanliness have become fundamental features.

Atmospheric air that is sucked into a compressor always contains a certain amount of moisture, dust and oil aerosols. These substances can impair production results and even increase costs.

Based on an efficient and simple technology, refrigeration dryers represent the preferred solution for the majority of these applications. Teamed with our line filters, our customers are able to produce high quality air with reduced dew point, air purity to ISO 8573-1:2010.

Sizing a Dryer

You need to match the volume (cfm - l/min) of the compressor to the flow of the dryer.

Rule of thumb when selecting, you can go bigger, but never smaller, if the air volume is too large, the dryer cannot reduce the air temperature down

 Water Contamination

Due to there being moisture in the air, there will be moisture in your air system. Heat is generated during compression and to make things simple we can say that the moisture is vapour (steam) when in this state the vapour will bypass to a large degree any filters you put in your system

What we require is condensation to take place by cooling, to some degree, due to tanks being a large surface area, this can happen there, and a simple filter installed, but if the air flow is constant, then another way is required that is more efficient, this is when you require a refrigerant dryer, especially when paint spraying, or running CNCs, this is just like your home fridge, but instead of keeping your food cold, it reduces the air temperature to 3-5 degrees ambient, once the vapour becomes a solid matter i.e. water droplets, it can be removed by a filter

 Todays compressed air production process is not only a matter of producing air, but also of confirming with defined purity criteria. , Refrigerant dryers are the right solution to remove condensate and continue efficiency.
