•  According to the principal of PSA, the moisture in the air will be adsorbed and compressed with the special appetency of the sorbent on the steam.
• The machine is of two-tower structure. Under the control of PLC, the two towers will run alternately. One tower adsorb the moisture under high pressure and another tower complete the desorption of steam with the dry air produced by itself, thus keeping running circularly.
• Although the machine will consume some air, the comprehensive energy consumption are largely lower than the heat sourced regenerative dryer based on variable temperature adsorption, so it is a widely used air compressing and drying machine at present.

1. Why compressed air purification? 

Compressor alone is not enough.In most cases,untreated compressed air is naturally dirty,oily and wet.This condition is certainly notdesirable for industrial applications and could directly or indirectlylead to the following situations.

•     Reduction in efficiency of expensive pneumatic tools & machineries

•     Frequent costly maintenance of pneumatic tools & machineries

•     Lost of production hours with increased machines down time

•     High rejection rate of products

•     Inability to meet delivery deadlines

•     Unsatisfied customers

Hence compressed air needs to be purified or treated before they can be efficiently utilised.With theincreasing popularity of compressed air as an alternative source of utility for today’s modern production facilities,it is essential that you select the most suitable compressed air treatment systems for your plant and budget this relatively small investment into your operations to avoid daily problems with untreated compressed air which could eventually lead to expensive additional operating expensesand loss businesses.

2. Why choose Sunfilter compressed air purification?
