<p class="MsoNormal">The choice really depends on you air requirements. We at Hmntl have two separate compressed air systems. Our 16 cleanrooms and facility use the standard CDA from a 100hp Sullair VSD rotary screw compressor. With this unit we have an external
600cfm dryer as well as a large demister to catch any oil that might escape the air compressor. If you have high air requirements this may be your best option. The cheap recip or rotary on tank systems are energy hogs and I personally would get a variable
speed unit with some type of ROI for energy. <o:p></o:p></p>

<p class="MsoNormal">Our BIO lab and a few other delicate labs needing better quality air(medical grade) use a multistage scroll unit. Its initial stage is a 5hp unit that maxes out at 25-30 hp. It is relatively small unit but very efficient. If I had a low

<p class="MsoNormal">Cfm requirement I would stick with a scroll system with multiple stage. The beauty of this system being if you lost a stage the next unit will step in and take over with out an outage.

These units are also very efficient. <o:p></o:p></p>

<p class="MsoNormal">We're in need of replacing our current scroll type compressors for our CDA system. A vendor is trying to sell us on an oil-flooded compressor with appropriate filters for our cleanroom CDA requirements. I would just like to see if anyone
else has a system like this and has anyone had issues with them. I believe oilless is the way to go, but would like to hear others opinions. I have read the ISO8573-1 spec.<br clear="all">
